SYSTEM AND METHOD OF GREENHOUSE GAS PROCESSING Russian patent published in 2018 - IPC B01D53/75 C01B31/20 

FIELD: chemistry.

SUBSTANCE: system includes a collection subsystem configured to collect a gas mixture containing carbon dioxide and methane, a combustion subsystem configured to burn specified methane in the said gas mixture and to output a gaseous combustion product stream, wherein the said combustion subsystem generates electrical energy, water and specified quantity of carbon dioxide; a blower configured to introduce ambient air to the specified gaseous combustion product stream downstream of the combustion subsystem, wherein ambient air cools the gaseous combustion product stream and dilutes the specified carbon dioxide in the gaseous combustion product stream, thus forming a mixture of ambient air and combustion products, wherein the specified gaseous combustion product stream has the first concentration of carbon dioxide, and the mixture of ambient air and the combustion products has the second concentration of carbon dioxide, wherein the second concentration of carbon dioxide is less than the first concentration of carbon dioxide, wherein the said second concentration of carbon dioxide is in the range of, at least, 5 wt % to a value less than the first concentration of carbon dioxide and the branch subsystem configured to separate the specified carbon dioxide from the mixture of ambient air and the combustion products and comprising: a heat exchanger arranged to contact with a mixture of ambient air and the combustion products and capable of lowering the temperature of the mixture of ambient air and the combustion products, thereby forming a cooled mixture, a dehumidifier arranged to contact with the cooled mixture and configured to remove, at least, a part of water, thus forming a cooled and dehumidified mixture, and a material for the physical absorption, arranged to contact with the cooled and dehumidified mixture and configured to remove, at least, a part of carbon dioxide from the cooled and dehumidified mixture.

EFFECT: improved processing method.
