Abstract (en)
[origin: WO2010145808A1] The invention relates to a method for reducing the emission of carbon dioxide into the atmosphere and to a tank for carrying out the method. According to the method, carbon dioxide, which was created as a result of a combustion process, is separated from the gas. The carbon dioxide is then brought to a pressure of at least 10 bar in absolute terms, preferably at least 15 bar in absolute terms, mostly preferably at least 18 bar in absolute terms, and is cooled to a temperature of up to -10°C, preferably of up to -20°C. Preferably, the temperature of the liquefied carbon dioxide is up to -40°C. The temperature of the liquefied carbon dioxide, during the transport in a tank, is especially preferably between -25°C and -35°C. The relatively high pressure of, for example, 18 bar in absolute terms requires the provision of tanks having relatively thick walls. However, the high pressure allows for a relatively high proportion of hydrogen and nitrogen to be accepted in the carbon dioxide gas. Thus, it is not necessary to separate nitrogen and hydrogen from carbon dioxide to a large extent prior to liquefaction, which would also cause a separation of carbon dioxide according to the available prior art.
