Feed-Gas Treatment Design for the Pearl GTL Project

Feed gas for Shell's gas-to-liquids (GTL) project in Qatar must be treated to meet the stringent contaminant specifications for a modern GTL process. This gas that contains hydrogen sulfide (H2S), carbon dioxide (CO2), several mercaptan species, and carbonyl sulfide (COS) requires a series of treatment processes. These processes must be selected and integrated to provide a cost-effective treating complex that removes contaminants in an environmentally friendly way. The full-length paper details the process selection method, indicating the process options available and the environmental benefits achieved.
