Best MRU Location in Gas Plant
Mercury is now recognized as a serious contaminants of gas and liquid hydrocarbon streams that must be removed to a level of less than 10 microns/ Nm3 and 0.1 ppbw for liquid hydrocarbon in order to protect the catalyst installed inside the dehydrators and the brazed heat exchangers (BAHE) and finally the environment from any mercury contamination.
Evaluation of different mercury data at downstream dehydration and upstream sweetening unit allows the engineer to select the best location in gas processing plant.
This presentation will discuss the positive impact on relocating the MRU from downstream dehydration to inlet facility at upstream of sweetening using a new mercury type of adsorbents where the main operation systems and operation people will be protected from mercury contamination.
