Abstract
The present invention deals with separating well fluids produced from a gas condensate reservoir into a condensate phase and a gas phase. The invention provides combining two stage separation, a stabilizer column and gas processing systems to achieve increased liquid yield and dry gas for take off (export) with much lower energy costs and capital costs. First stage separation pressure is maintained between 600 psi and 1500 psi. Second stage separation pressure is maintained at a higher pressure than that required to achieve the liquid vapor pressure specification, usually between 400 psig and 600 psig. The stabilizing column produces a stabilized liquid (preferably having a vapor pressure about 8.2 psia at 80.degree. F.) by operating the column bottom at approximately 240.degree. F./50 psig.
