  • Patent number: 5502266
    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 F.) by operating the column bottom at approximately F./50 psig.

  • Patent number: 4948393
    Abstract: The invention deals with separating production fluids into separate components of oil, water, sand and gas in first and second stage separators. Preheating of the production fluid prior to entry into the first stage separator is partially accomplished by direct mixing with hot processed water taken from the effluent of the first stage separator and the second stage separator. Recirculated processed water may also be used to improve sand removal from the first and second stage separators.
