APPARATUS, SYSTEM, AND METHOD FOR CONTROLLING COMBUSTION GAS OUTPUT IN DIRECT STEAM GENERATION FOR OIL RECOVERY

摘要

An apparatus, system, and method for controlling combustion gas output in direct steam generation for oil recovery. A direct combustion steam generator burns a fuel and an oxygen-containing gas mixture to produce combustion products including steam, C02 and N2. Supplemental oxygen is separately supplied to the combustion steam generator to adjust the oxygen content of the oxygen-containing gas mixture during the combustion process in order to adjust the ratio of C02 to N2 produced in the combustion products.
