Comparison of Amine-based TGTU Technologies Article from Hydrocarbon Engineering with Flexsorb reference

An important aspect of the sulfur recovery/amine-based tail gas treatment unit is to maximize hydrogen sulfide absorption while minimizing carbon dioxide co-absorption. Selective treating permits the full utilization of the solvent for H2S removal by releasing the capacity otherwise occupied by the CO2, thereby reducing circulation rate and increasing efficiency. This article compares the stability and long term performance of applicable technologies and operating units
