A multi-phase amine facility was being built to ultimately process 1.6 Bscf/D (45,300 e3m3) of gas. Each phase of construction included two amine facilities, each with a capacity of 200 MMscf/D (5,600 e3m3). Four phases or more were anticipated. CHALLENGE Gas flowing into the amine facility was expected to contain up to 12% CO 2, resulting in a relatively large acid gas stream. To treat the acid gas stream, each amine train was designed to be directly followed by a four-train acid gas sweetening unit (AGSU) with each AGSU capable of treating app
