Shell's Sulfinol and SCOT processes have been combined in a new cascade treating system, now successfully field-tested. The new process results in significant capital and operating costs savings. Introduced in 1964, the Shell-licensed Sulfinol process removes acidic compounds from sour gas streams. It has been employed in over 150 plants world-wide. The process uses a conventional absorption regeneration cycle quite similar to that utilized in amine gas treaters. Sulfinol is rather unique among treating processes in that the solution contains both a chemical agent, usually aqueous DIPA (diisopropanolamine), and a physical solvent, sulfolane. As would be expected, the process displays many properties and advantages of both chemical and physical processes, e.g., high acid gas loading of the solution, low regeneration heat requirements, and capability to treat to very low residual levels of H/sub 2/S and CO/sub 2/. The cascade SulfinolSCOT process has been successfully operated at the Eustace plant, overcoming solvent contamination and earlier equipment problems. This process has significant potential to reduce capital costs and operating expense. It should be considered for applications requiring both acid gas removal and sulfur plant tail gas cleanup.
