95/05436 A zero emission combustion power plant for enhanced oil recovery

Abstract

-We have studied an internal combustion CO 2 power plant to enhance oil recovery. The plant has air separation of O 2 for combustion and of N 2 for injection, a combustion chamber, a turbine, a compressors, a recuperator, and a cooling tower. The oil-derived gases are used to produce liquid CO 2 , highly compressed N 2 , process steam and, if necessary, power. No exhaust gases are released. The plant design is presented along with efficiency calculations. The plant should be of interest for offshore oil production.
