SYSTEM OF LIQUEFYING CARBON DIOXIDE FROM MIXTURE OF EXHAUST GASES, USED IN AIR-INDEPENDENT HYDROCARBON FUEL POWER STATION Russian patent published in 2009 - IPC F25J1/00 

FIELD: heating.

SUBSTANCE: invention relates to the field of power engineering, particularly anaerobic power engineering and can be used in air-independent power stations (PS) with thermal engines and electrochemical generators. System of the liquefaction of carbon dioxide from a mixture of exhaust gases, used in an air-independent hydrocarbon fuel power station, includes a gas-collecting compressor, moisture separator, distributing pipes for the mixture of exhaust gases, condensing section for the carbon dioxide, concurrently connected with the distributing pipes for the mixture of exhaust gases and having an inlet nozzle and an outlet nozzle for cooled oxygen, evaporator of the liquid oxygen with an outlet nozzle for gasified oxygen, separator for unliquefied gases and a collector of liquid carbon dioxide, cooler for the mixture of exhaust gases with one or two inlet nozzles for gaseous oxygen. In the evaporator for liquid oxygen, placed vertically, are built heating elements, for example pipes, which are divided in groups by numbers, equal to the number of condensation sections for carbon dioxide, with one and the same number of heating elements in each group, joined for each group under a common inlet and outlet nozzle heating gaseous oxygen. Inlet nozzle heating gaseous oxygen is connected using a pipe to the outlet nozzle of the cooling oxygen from the condensation section, and the outlet nozzle heating the oxygen from each group of heating elements of the evaporator is connected using a pipe with the inlet nozzle of the cooling oxygen in the condensation section. Outlet nozzle for gasified oxygen from the evaporator is connected using a pipe with the inlet nozzle of the cooling oxygen in the first along the flow of recirculating oxygen in the condensing section. Outlet nozzle heating oxygen from the last group of heating elements is connected with a pipe through a valve with one of the inlet nozzles of gaseous oxygen to the cooler of the mixture of exhaust gases, and the outlet nozzle of gaseous oxygen from the last along the flow of recirculating oxygen in the condensing section is joined with a pipe through a valve with another inlet nozzle for gaseous oxygen to the cooler of the mixture of exhaust gases.

EFFECT: design of an efficient system of liquefying carbon dioxide from a mixture of exhaust gases.
