A zero emission combustion power plant for enhanced oil recovery

We have studied an internal combustion CO2 power plant to enhanced oil recovery. The plant has air separation of O2 for combustion and of N2 for injection, a combution chamber, a turbine, a compressors, a recuperator, and a cooling tower. The oil-derived gases are used to produce liquid CO2, highly compressed N2, 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.
