FIELD: process engineering.
SUBSTANCE: invention relates to gas separation with the help of membranes, particularly, to application of blow gas on membrane permeate side for removal of carbon dioxide from combustion products. Proposed method comprises trapping carbon dioxide from combustion products to form waste gas flow with lower concentration of carbon dioxide than that in effluent flow, forcing portion of waste gas flow through membrane feed side, forcing air enriched with air oxygen or oxygen as blow flow through membrane permeate side, extracting waste flow with decreased content of carbon dioxide from the membrane feed side and extracting permeate flow bearing oxygen and carbon dioxide from membrane permeate side.
EFFECT: efficient removal of carbon dioxide, power savings.
