ADSORPTION INTEGRATION UNDER VARIABLE PRESSURE WITH AN ENERGY INSTALLATION FOR CO2 COOLING / DISPOSAL AND N2 PRODUCTION

摘要

1. A method of generating energy, comprising: compressing a recycle exhaust gas in a main compressor to produce a compressed recycle exhaust gas, wherein the compressed recycle exhaust gas has a recycle temperature of from about 400 ° C to about 500 ° C and a recycle pressure of from about 1.0 MPa abs . (about 10 bar abs.) to about 3.0 MPa abs. (about 30 bar abs), while the recirculated exhaust gas contains at least about 70 vol. % N and at least about 10 vol. % СО; compression of the enriched air in the inlet compressor to produce a compressed oxidizer; passing the first part of the compressed recycle exhaust gas into the combustion chamber; stoichiometric combustion of the compressed oxidizer and fuel in the combustion chamber in the presence of the first part of the compressed recycle exhaust gas, thereby obtaining a discharge stream, where the first part of the compressed recycle exhaust gas acts as a diluent designed to reduce the temperature of the discharge stream; expanding the discharge sweat in the expander for at least partially driving the main compressor and generating recirculated exhaust gas; passing a second part of the recirculated exhaust gas into the short-cycle adsorption reactor containing adsorbent material; adsorption of CO on the adsorbent material at an adsorption temperature that differs from the recycling temperature by less than about 20 ° C, and at an adsorption pressure that differs from the recycle pressure by less than about 0.1 MPa (about 1 bar); extract stream Nc purity of approximately 95 vol. %, from the front end of the reactor, and the extracted stream
