At high pressure with high acid gas partial pressure.1. amine processes will be appropriate (DEA."OIL AND GAS PROCESSING PLANT DESIGN AND OPERATION TRAINING COURSE" DGEP/SCR/ED/ECP "GAS SWEETENING PROCESSES" 2002 Page 40 2. and DGA processes will be considered in addition to amine processes.
In conventional gas processing H 2 S and CO 2 are removed in an acid gas removal unit (AGRU) using aqueous amine absorption processes. The sweetened gas leaving the amine process is saturated with water, so typically the AGRU is located upstream of the dehydration facilities.
