Hydrocarbon/CO{sub 2}/water multiphase equilibrium separations. Final report, July 1, 1993--September 30, 1995
- Texas A and M Univ., College Station, TX (United States)
Hydrocarbon (HC)/water and HC/CO{sub 2}/water systems are frequently found in petroleum recovery processes, petroleum refining, and gasification of coals, lignites and tar sands. Objective is to provide techniques for analyzing these mixtures at pressures up to 10,000 psia and temperatures up to 500 F; two laboratory apparatus were developed for this purpose. Three-phase separation data are obtained for mixtures of pure n-alkanes (C{sub 3} to C{sub 20}), CO{sub 2}, and water; and for mixtures of pseudocomponents of crude oils and water. Crude oils are characterized using a modified Whitson`s method. Rigorous equation-of-state computer simulators were developed and validated with experimental data; they are essential for reservoir engineering and enhanced oil recovery.
