摘要： A method for removing and preventing emissions into the atmosphere of carbon dioxide (CO2) from exhaust gases from heat engines, particularly gas turbines, installed on offshore platforms for the production of oil and/or gas, which is characterized by the following steps: (a) natural gas and air are introduced into a heat engine in which natural gas is converted to mechanical energy, (b) the exhaust gas from the heat engine is passed through a heat recovery plant, preferably a waste heat boiler, for recovery of the heat content in the exhaust gas in the form of steam, (c) after emitting heat in the heat recovery unit whereby the temperature of the gas has been reduced to 20-70 DEG C, the exhaust gas is passed to an absorption column containing an absorption liquid, where the carbon dioxide is absorbed in the said liquid, and the thereby purified exhaust gas, generally free of carbon dioxide, is vented to the atmosphere, (d) the absorption liquid which contains CO2 is passed to a stripping column where the CO2 is removed from the absorption liquid by means of heating to a temperature of 120-150 DEG C, (e) the thereby regenerated absorption liquid which is generally free of CO2 is recycled to the absorption column and the separated CO2 gas is passed to a compression stage for compression and utilization and/or disposal in a suitable manner.
