The use of aqueous, liquid redox desulfurization technology for the direct treatment of sour associated and process gas streams at elevated operating pressure and relatively high CO2 partial pressure presents unique design and operational challenges. The LO-CAT II® process, an aqueous liquid redox process that utilizes a ferric (Fe+3)/ferrous (Fe+2) amino-carboxylate redox couple, installed at the MOL Gas Plant in Szeged, Hungary has performed to specification. However, to achieve this goal, resolution of technological challenges related to the solution circulation pump; absorber pluggage with associated high system pressure drop; liquid hydrocarbon influx; foaming with associated liquid entrainment; and corrosion were required.
The design and operational history of the facility is presented, and the aforementioned technological challenges and their resolution are discussed.
