Accelerating the Transition

Digital Technologies to Accelerate Decarbonization of Gas Processing Facilities

Bart de Groot, Siemens Process Systems Engineering Limited

The gas processing industry is under increasing pressure from customers, governments, shareholders, and society as a whole to reduce the carbon footprint of their products and processes. As a result, many are adopting ‘net zero’ goals, and are developing strategies to achieve these goals. Invariably these strategies include transitioning towards (1) the production of hydrogen via a variety of routes, (2) carbon capture, utilization and storage, and (3) the use of bio-based feeds for the production of fuels.

For many of these technologies, challenges remain to scale up, reduce costs, integrate into wider process systems and increase confidence and acceptance.

In this presentation, we present how digital design techniques based on can help speed up technology development, map system interactions, determine optimal buffer sizing, especially in highly transient scenarios, optimize equipment and system designs, and ultimately provide reassurance to all stakeholders to confidently navigate the road to decarbonization.


Which Treatment Scheme to Select for Biogas Valorization? Story of a Technical Conceptual Study and Upskilling from Natural Gas to Biogas Industry

Celine Volpi, TotalEnergies

TotalEnergies ambitions to produce 2 TWh/year of biogas in 2025 and more than 5 TWh/year in 2030. The industry must adapt to ensure sustainable production of biomethane at large scale but also, for each company, to upgrade / adapt technical skills leverage on the historical actor.

Several biogas valorization’ schemes and technologies have been evaluated for a large capacity project in Europe. Is the widespread technology for biogas still the most adequate for large scale unit? Or should we select the standard technologies for natural gas?

The first step was to define the basis of design, including the future regulations and market constraints. Then, cleaning and upgrading process schemes are compared from technical, sustainability and economical points of view. The presentation will highlight the identified differences with natural gas treatment.


Comparison of Process Options for Sustainable Ammonia Production

Filip Čejka, Bryan Research & Engineering

Ammonia is one of the most produced chemicals in the world, with a production of about 150 million metric tons a year.  It is critical for improved yields in modern agriculture as well as a chemical feedstock to various other processes.  Today, Steam Methane Reforming (SMR), which uses fossil based natural gas as its feedstock, is the most widely used method for ammonia production.  In this process, the natural gas is used to produce hydrogen, which is then reacted with nitrogen from the air to form ammonia.  This technology generates a significant amount of greenhouse gases (GHGs), which has led to proposals for new processes that lower the carbon intensity of ammonia production while still maintaining process efficiency.

One approach for reducing GHGs from the conventional SMR process is either sequestration of vented CO2, carbon capture from process flue gas, or a combination of the two.  These methods have sometimes been dubbed “Blue Ammonia”.  Another approach, sometimes called “Green Ammonia”, utilizes water electrolysis as its source of hydrogen.  The use of water electrolysis allows water and renewable sources of electricity, such as wind and solar, to supplant natural gas as the feedstock for the required hydrogen production.  Two categories of electrolysis units include alkaline water electrolysis (AWE) and polymer electrolyte membrane electrolysis (PEM). While the SMR process can use air as its source of nitrogen, the AWE and PEM based technologies require pure nitrogen to be available.  A third category of electrolysis, solid oxide electrolysis (SOE), can also generate pure hydrogen from renewable electricity, but unlike AWE and PEM, does not require pure nitrogen.  SOE also provides additional avenues of heat integration between hydrogen production and ammonia synthesis that is lacking from the other electrolysis technologies.

A comparison is made between the various newer technologies to a conventional SMR system  using a steady-state simulator.  This comparison includes the configuration and requirements of each system, as well as each system’s carbon intensity and power requirements per ton of ammonia produced.


Non-Thermal Microwave Plasma Conversion of Methane to High Value Acetylene (and Hydrogen)

Paul Hudson, Transform Materials

Valorisation of methane by conversion to other products will be increasingly important as decarbonisation efforts change energy production. Electrification of gas fired ethylene crackers for example, will free up significant volumes of methane which will be available for conversion into higher value products via green processes. Transform Materials non-thermal microwave plasma process converts hydrocarbons directly to acetylene without producing CO2 in the reaction – in fact the only ‘by product’ is high purity hydrogen!

Use of renewable gas and green energy means this process can even be carbon negative, meaning green acetylene can be converted to things like green polymers e.g. PVC via VCM! The TM process is scalable, modular and can be deployed more locally to acetylene end users meaning simplified and greener supply chains and logistics.


A Physical Solvent Approach to Carbon Capture and its Applications for Blue Hydrogen

Charlie Gould, Fluor

Hydrogen production and carbon capture are major stepping stones towards a decarbonised future and are expected to be key components of the world’s energy transition away from fossil fuels. New low-cost technologies are critical to advancing these efforts.  Bulk removal of CO2 is typically performed using an amine-based solvent such as MDEA (methyl-diethanolamine).  However, in many applications with high CO2 partial pressures and little to no H2S, a better option may be a physical solvent, such as propylene carbonate, as used in the Fluor SolventSM process. Propylene carbonate is a non-corrosive, non-toxic, and biodegradable solvent, capable of achieving equal levels of CO2 capture with an estimated 80% reduction in primary energy input compared to a conventional amine-based CO2 removal system.

This paper explores the use of propylene carbonate to capture CO2 from existing or new-build hydrogen production plants (SMR, ATR, or POX) and recovery of that CO2 for carbon sequestration or EOR to produce Blue Hydrogen.  In the example considered in this paper, the carbon capture unit is located downstream of the water-gas shift reactors in an ATR plant and upstream of a conventional PSA unit.  The captured CO2 stream will have sufficient CO2 purity for sequestration or other industrial uses.  This paper presents CO2 capture levels, captured CO2 purity, total utilities consumption and other key aspects of the process to provide a comparison between propylene carbonate and a conventional amine-based CO2 removal system.


Clean Hydrogen Purification with Catalysts and Adsorbents

François-Xavier Chiron, Axens

Regardless of its color (green / blue / pink / white / …), hydrogen will certainly play a major role in the industry energy transition and the future of transportation. While a lot of efforts are naturally put to decrease the CAPEX of clean Hydrogen production, purification is often seen as a black box that still has to deliver up to 99.999 vol % H2. Hydrogen coming out of a manufacturing process (methane reforming / Electrolysis) or stored geologically come together with an array of impurities: oxygen, water, carbon oxides and sulfur to name the major components. Usages in mobility via a fuel cell or the use of hydrogen as a reactant in a catalytic conversion impose tight specification especially on oxygen and water.

This paper focuses on some key purification steps that use catalysts, adsorbents or scavengers to meet the required hydrogen purity.

The first application is the PDU (Purification & Drying Unit) located directly downstream an electrolyser. This purification package includes a deoxo catalyst (Axens commercial name is DO 125) and molecular sieve driers packed in a “zero-loss TSA system”. Depending on the electrolysis technology (AEL / PEM) hydrogen comes out with different levels of oxygen, but always water saturated. Oxygen is easily reacted with hydrogen over a precious metal catalyst: H2 + ½ O2 = H2O. Axens has developed in its historic facility at Salindres, France, a very active Pd based catalyst, supported on a specific alumina. Subsequently, the gas is cooled down and water is knocked out before entering the dehydration section. Based on years of experience in refining and Natural gas treatment, the drying section utilizes Axens MultiBed™ configuration so that water levels as low as 0.1 ppm mol can be guaranteed at the PDU section outlet.

Similarly, a PDU can be installed on blue hydrogen, just downstream the PSA. This unit is very similar to the PDU on electrolysers, with the difference that it is not O2 that has to be removed but traces of CO/CO2. Carbon oxides are well known poisons to fuel cells as well as for catalyst used in the hydrogenation of toluene for LOHC application for instance. Axens proposes MT 201 R, a pre-reduced methanation catalyst that effectively brings the CO/CO2 level to ultra-low concentration. Methanation is classically followed by a zero-loss TSA system, integrated on a skid.

Other purification with Axens adsorbents include the purification of white H2 (native H2) and hydrogen stored in salt caverns where hydrogen comes out enriched in sulfur. Sulfur scavengers produced in Axens factory in Saint-Louis are used to bring the hydrogen back to the highest standard.

Originating from years of experience in Adsorbents and Catalysts manufacturing, Axens proposes purification solution on all kind of hydrogen streams so that any specification can be met.

COMPMEM is a joint industrial project initiated by Aker Carbon Capture (ACC) aiming at the validation and pilot scale demonstration of membrane-based process for subsea CO2 separation. The separated CO2 is to be reinjected to increase recovery rates in offshore oil and gas fields.

Firstly , four membrane qualities have been tested in the lab scale at the conditions relevant to subsea gas separation – within the broad range of temperature (40-90 oC), feed (35-90 bar) and permeate (2-35 bar) gas pressures, and CO2 content in the feed gas (10-90%). To cover such a broad range of operating conditions with minimum possible number of experiments, statistical design of experiments principle was applied.

Based on the results from these experiments and compatibility testing of the membrane materials and potting materials with harsh conditions potentially present at sub-sea conditions, only two membrane qualities were selected for further testing in small-industrial scale rig built at SINTEF.

Results from the lab-scale testing of the membrane performance and description of the pilot scale test rig and its test results will be presented.



Traditional Gas Treatment

Degradation of Desiccants Beyond Hydrothermal Stability

John Jacobs, University of Calgary

Industrially, thermal swing adsorption using molecular sieves is a common technique to dehydrate natural gas. These systems are designed to operate for years at a time, with adsorbent materials subjected to thousands of cycles. Despite all the efforts into adsorption research, there is very little open literature on the degradation of these materials over prolonged cycling before selection for service. Herein, we describe a novel instrument, capable of thousands of thermal swing adsorption cycles in a short period of time for multiple samples and different gas compositions. The degrading of zeolite 4A, zeolite 13X and three different pore size silica gels was investigated using this instrument. By measuring the change in performance of the materials after 5000 temperature swing adsorption cycles, insights into the mechanisms of degradation and the role of CO2 in the degradation have been elucidated.


Improvement of Process Efficiency for Natural Gas Applications by Fujifilm Apura™ Gas Separation Membranes

Davide Bocciardo, FUJIFILM

In the last several years membrane-based gas separation applications are gaining a larger acceptance in the Oil & Gas industry and are competing with conventional purification technologies such as Amine Towers, Pressure Swing Adsorption (PSA) and Cryogenic Distillation.

Fujifilm has a long-standing experience in multi-layer coating and in high quality performance of manufacturing processes, which are based on photographic film manufacturing. This is the foundation for the development of highly functional membranes for gas separation which has been commercialized in 2014 under the brand name Fujifilm Apura™. There are two main applications for Fujifilm Apura™: natural gas sweetening for by Apura™ and for fuel gas conditioning by Apura™-FG.

Fujifilm Apura™ technology has been proven by several worldwide installations including competitor replacements. Fujifilm Apura™ proved superior performances compared to competitor gas separation membranes, which led to plant efficiency improvement and reduction of CO2 and Volatile Organic Compounds (VOCs) emissions.

This presentation will introduce the Fujifilm Apura Gas Separation technology and will also cover case studies where Natural Gas operators successfully deployed Fujifilm Apura™ membrane modules.


Reducing Methane Emissions in the Energy Sector: A Team Effort

Angelo Lo Nigro, RINA

Natural gas has been listed few months ago as environmentally sustainable in the EU Taxonomy Regulation, subject to satisfaction of certain criteria, such as on emissions limits. This will certainly help the development of the new LNG infrastructures we need to enhance the security of our energy system, as the recent war in Ukraine has emphasized: natural gas is, and will continue to be, a key energy source during the energy transition.

As more natural gas could mean more methane emissions, which we cannot afford, on December 2021, the European Commission published the proposal for a regulation on “methane emissions reduction in the energy sector and amending Regulation (EU) 2019/942”. Methane indeed is responsible for about 30% of current global warming, second only to CO2. According to UNFCCC, the Energy sector is responsible for 18% of anthropogenic methane emissions, corresponding to 129 bcm/year, almost twice Italy’s consumptions, and with high potential for a rapid, efficient, and effective reduction (up to 41% at no cost, according to IEA). Once issued, the regulation will be immediately in force across the Union, showing the strong commitment to expedite the implementation of the measures to reduce emissions across Europe. The main objectives of the regulation are the adoption of the highest MRV standards, the immediate reduction of emissions through mandatory LDAR, and the ban on venting and flaring, and the transparency on emissions related to gas imported into the EU.

The proposal is certainly an important milestone, and it can help achieving our common goals, but methane emissions were already in our agenda, with significant results already been achieved by various operators.

RINA has been involved in various projects worldwide along the whole value chain: technology assessment, plant design, O&M engineering, plant inspection, monitoring, and reporting. All with a focus to reduce methane emissions.

RINA is also contributing to the Assorisorse working group on methane emissions, which recently released a white paper on the matter.

The presentation will provide an overview of the international activities, regulations and working groups addressing methane emissions, and will show some case histories taken from RINA references, which include the application of novel technologies and the development of advanced tools and methods to reduce emissions in existing oil & gas infrastructures.


Minimizing the Energy Consumption of a Carbon Capture Unit Installed on a Steam Methane Reformer While Limiting its Impact on Overall Design

Clement Salais, Axens

Hydrogen is seen as a future major energy carrier. However, current hydrogen production technologies from fossil fuels (so-called “grey” hydrogen) emit considerable amounts of CO2 as a co-product and carbon-free technologies (such as for instance “green” hydrogen produced through electrolysis of water with renewable electricity source) are still in early stages of development. One mid-term solution to reduce CO2 emissions in an attempt to reach COP21 objectives for 2050 is to capture CO2 released by the production of hydrogen from fossil fuels.

This paper focuses on carbon capture (CCS) in the syngas produced in a steam methane reformer (SMR) using the reactive absorption of CO2 with an amine solvent and its impact on the SMR design.

AXENS as Licensor of AdvAmine™ technology for gas sweetening process and provider of reformer furnaces through its Heurtey Petrochem brand detains an independent expertise for the evaluation of optimum design conditions of the amine system to minimize OPEX of the CO2 capture, and for the evaluation of the impact on the reformer, as well as the overall carbon footprint of the hydrogen produced, under the various considered process configurations.

In a first step several process schemes, using AdvAmine™ for the carbon capture from a syngas flow exiting a SMR unit are investigated and compared to minimize the energy consumption. To do so, the studied schemes are optimized by process simulation using a dedicated proprietary software, sized and then compared with techno-economic criteria.

In a second step, this paper evaluates the impact of removing CO2 from the syngas with such amine process, on the overall design of the SMR. The removal of CO2 from the syngas significantly modifies the composition at the inlet of the hydrogen purification through Pressure Swing Adsorption (PSA). Even though it may lead to only minor modifications on the PSA required for the purification of hydrogen, this change in PSA feed gas composition will drastically change the composition of the PSA purge gas. This PSA purge gas being recycled as a fuel to main SMR furnace, this will then impact the reformer section design and operation. Accordingly, the impact on the overall balances for make-up fuel requirement, steam production and overall CO2 footprint of the SMR are addressed considering two distinct scenario cases: the SMR grassroot design and existing SMR revamp case. Heat integration between the reformer and the amine carbon capture unit have also been considered, in order to optimize the overall process configuration. The specific constraints of the revamp case, for which some of the existing equipment items cannot be modified, lead to a less effective carbon capture than for the grassroot case.

How to develop an optimal design considering the integration of all process units. Highlighting that it is generally the contaminants that control the selection of units. Will then provide details of 2 case studies showing that different designs were recommended for different projects and explaining why. Both cases required H2S, mercaptan removal and CO2 recovery.

Case 1

Dehydration & Mercaptan Removal – Molecular sieve

Regeneration Gas Treatment – Physical Solvent

SRU 2-stage SRU & TGTU same solvent as AGEU & Common regeneration


Case 2

Case 1: Simplified Integrated Solution with Improved Economics - Sales Gas Production from a Lean Natural Gas containing Mercaptans

Lean acids gases with mercaptans are difficult to treat. In order to achieve sales gas specifications as well as air emissions specifications in the flue gas several process units are required resulting in a complex scheme with high CapEx and OpEx and big footprint. The typical scheme consists of a Gas Sweetening Unit with amine solvent in order to remove H2S and CO2 followed by molecular sieves with dedicated regeneration to remove mercaptans to meet the total sulphur specifications. Next the acid gas from amine regenerator is typically sent to a Claus unit for sulphur recovery followed by an amine based Tail Gas Treatment to ensure flue gas SOx specifications.

This study shows an industrial design realized by Axens for a new project in the Middle East. A different and simplified scheme has been implemented with optimized and efficient process solutions in order to deliver sales gas at commercial specifications, reducing the overall investment and production costs.

This scheme consists in the following process and catalyst solutions: A Gas Sweetening unit with a hybrid solvent using the HySWEET™ technology in order to simultaneously remove CO2, H2S, COS and mercaptans in a single unit. Sweet gas from the HySWEET™ unit meets total sulphur specifications and only needs to be dehydrated  using TEG to reach commercial sales gas specifications. The acid gas from the HySWEET™ regenerator is sent to a sub dewpointing sulphur recovery unit using the Smartsulf® technology. This technology allows operating below the sulphur dew point increasing the sulphur conversion up to 99.5% with a simple arrangement of a reactor furnace followed by two proprietary catalytic reactors without the need of implementing high cost intensive amine based Tail Gas Treatment Unit. A final polishing solution with caustic is added at the outlet of the Incinerator in order to reach more than 99.9% sulphur removal and reach SO2 emissions specifications of 250 ppmv @ 3% O2 dry basis.

This study provides an overview of the global scheme with a brief explanation of main technologies and catalyst involved. A comparison of CapEx, OpEx and footprint with a conventional scheme is presented.


Case 2: 1100 MMSCFD single train AGRU treats lean gas with BTX within an integrated AGRU + low BTX Enrichment Section + TGTU absorber for a Middle East LNG plant

Upgrading acid gas treatment at one of the world’s largest LNG facility safeguards the plant’s design capacity and its ability to process increasingly sour feeds.

In this existing LNG plant the customer wanted to maintain LNG production while processing a feed with higher quantity of CO2 and H2S, meeting the same sales gas specifications, limiting modifications of the existing units and with limited available plot space.  

The existing gas plant included a gas sweetening unit, acid gas enrichment unit and sulfur recovery unit with tail gas treatment. However, with the increase in gas throughput and change in feed gas quality, the existing gas sweetening unit was not able to handle the additional gas with respecting the treated gas specifications. It was decided to add an additional gas sweetening unit upstream to remove both H2S and CO2 to offload the downstream units and a dedicated sulfur recovery unit including tail gas treatment.

One of the challenges to be addressed for the design of the new AGRU, SRU and TGTU of the project was to treat 1100 MMSCFD of a lean gas containing BTX and to recover 880 TPD sulfur within a limited surface area allocated to the project. This challenge was successfully met thanks to the integration of the enrichment section and the TGTU absorber with the AGRU. The proposed scheme is based on a patented Process of the AdvAmine™ technology licensed by Axens.

This study shows the evolution of the new process scheme that was implemented to include a new gas sweetening unit and the integration of the unit with a new sulfur recovery unit. As there was limited plot space available and challenges on the acid gas quality to feed the new SRU, Axens was able to propose an integrated solution of gas sweetening, acid gas enrichment and tail gas treating with a common regeneration.

The final scheme selected using Axens AdvAmine™ technology includes a high pressure gas absorber, a low BTX pre-flash tower to enrich and lower the BTX in the acid gas, and a TGT absorber for the SRU all with a common regenerator. This scheme was able to meet the treated gas specifications of <600 ppmv of H2S and <1.8 mol% CO2 on the high pressure absorber, <250 ppmv H2S on the TGT absorber, <50 ppmv H2S on the flash gas, >54 mol% H2S and < 300 ppm BTX in the acid gas from the regenerator. The scheme was optimized to fit into a reduced plot space and to minimize the utility consumption.

Panel Discussion

Two-hours bringing participants fascinating debate and big picture outlooks from some of the big names in the gas processing industry.


2022 : Gas in Europe at the hour of crisis : how our industries responds to the current challenges


We face of year of big surprises, most of them being probably uncomfortable, and a double crisis:

  1. The end of supply of Russian gas, that was anticipated as the substituent energy when the renewables resources could non-sufficient (wintertime, anticyclonic periods, no wind)
  2. Energy Transition by itself and we have seen that 2022 was amongst the hottest year of modern times with general drought in western Europe, natural disasters: 60000 Ha of wild forest burnt in France (10x yearly average)


In the meantime, we see a continuous acceleration of project and investments, as well in the industry of ET, with notability new emerging sectors, and a pushing forward wave of projects in CC and sequestration of CO2. I would say for remind, Islandic DAC start-up, EPC of Celsio CC plant in Oslo, Norway which drives Northern Lights forward. We also a lot of project in production of natural gases that have sanctioned and build reinjection and sequestration of native CO2.

This panel will question a team of very influential contributors, recognized in the Industry for their role and their knowledge in the on-going transformation of the market of gas in Europe, and also new market that could be also considered as gas, including CCUS or decarbonized gases. Even before the Ukrainian crisis, the gas industry in Europe had engaged a deep transformation, decarbonizing the production, developing alternate source of energies acting in the decarbonization of the energy supply and developing / promoting new technology solutions of the energy transition, like CCS.


Our panel includes and GPAE has the great honor to welcome:

  • Nick Flinn, GM Decarbonisation Technologies, Shell Global Solutions
  • Claire Weiss, Gas & Low Carbon Lead, TotalEnergies
  • Christian Streicher, Gas Development Director, Axens
  • Armelle Lecarpentier Chief Economist, Cedigaz
  • Phil Hagyard/Dominique Gadelle, VP LNG, TechnipEnergies


After a brief opening statement from each of the panel members, the floor will be open to questions from the audience on any subject.

To help the proceedings flow, they will be facilitated by Gauthier Perdu, a member of the GPA Europe Management Committee.

Questions can be posed via an on-line app, or via microphone.
