METHOD TO PRODUCE POWER, COLD AND CARBON DIOXIDE FROM SMOKE GASES Russian patent published in 2013 - IPC F25J3/00 F25B11/00 F01K25/00 

FIELD: power engineering.

SUBSTANCE: method includes moisture removal from cleaned smoke gases, compression and cooling of cleaned and dried smoke gases, trapping of carbon dioxide in solid condition from smoke gases and their expansion in the turbine for generation of power and cold. The process of trapping carbon dioxide from smoke gases is carried out by combination of a refrigerating cycle with a steam-force Rankine cycle, in which a low-boiling working medium of light hydrocarbons class, for instance, ethane, performs the function of a coolant in process of trapping of carbon dioxide in solid or gaseous conditions in the refrigerating cycle.

EFFECT: deep trapping of carbon dioxide from cleaned smoke gases in solid or gaseous conditions without external costs of cold and energy, and also their additional generation with full liquidation of thermal contamination of environment.
