Power production method using gas turbine principle

摘要

The method involves mixing a 95-99.50 mol.% oxygen rich flow (1) and a 90-95.99 mol. % CO2 rich flow (20) using an ejector (2), which is then compressed. The compressed flow is burned off (6) with a hydrocarbon rich combustion gas flow (7), and expanded in the exhaust gas. Water is extracted from the expanded flow (10,20), and the remaining CO2 flow (3) is fed back as required. The residual CO2 (22) is dried, by using a supply of methanol and/or glycol (42) or by adsorption, and then pumped to a pressure between 50 and 500 bar, pref. between 250 and 350 bar. the residual CO2 is then fed in deep water, in an aquifer, in a redundant oil/gas reservoir and/or a gas reservoir yet to be located. The flow produced in the ejector has pref. less than 5 mol. % nitrogen, 13 to 20 Mol. % oxygen and 70-87 Mol. % CO2 as well as a molecular wt.% between 35 and 43.
