According to your diagram， firstly you should define the lean amine circulation rate according to the acid gas you want remove, the calculation sheet is provided by cheresource according to GPSA databook,you could downloaded it freely. The temp of the sour gas is proper, you should adjust the temp of lean amine ,may be 6 ℃ upper than the feed gas(if utility is available). i donot know your hysys versions, may be if you attatched your model, i can help you.
