摘要： The invention relates to a process for producing oxygen or air enriched with oxygen, in which process: The air entering the process is cooled in a heat exchanger (14) to near to the condensation point of air and the air is led to a separation unit (10) formed of two or more chambers connected thermally to each other and comprising A and B halves (11, 12), in which it is divided, using liquidization and evaporation processes, into two or more gaseous fractions. The process air is maintained at normal temperature, except for small pressure differences to maintain the flow of the air and to optimize the process. When the process air flows through the A half of the separation unit, the liquid oxygen concentrate separated from it is evaporated in the B half (12) of the separation unit at such a pressure, lower than normal pressure, that the desired composition is obtained for the oxygen concentrate and the heat of liquidization released in the A half (11) of the unit is transferred to the B half (12) of the unit and is bound in it to the evaporation of the oxygen concentrate. The low-oxygen-content process air leaving the A half (11) of the separation unit is led out of the process through the heat exchanger (14). The oxygen concentrate evaporated in the B half (12) of the separation unit exits at the lower than normal pressure prevailing in the half in question, either as such, or through a boosting and cooling process to the heat exchanger (14), and from there out of the process. The liquidization and evaporation processes are carried out in the said separation unit (10) in nearly reversible conditions, in such a way that the gas phase in each process and in each part of the separation unit is nearly in equilibrium with the liquid phase in the same part.

摘要： The invention relates to a process for producing liquid carbon dioxide (CO 2 ) from combustion gas at normal pressure, in which process the CO 2 of combustion gas led to the lower part of an absorption column (11) is absorbed in an absorption solution that flows downwards from its upper part; the CO 2 -poor combustion gas is removed from the upper part of the absorption column (11); the said absorption solution is led to the upper part of a desorption column (12); the CO 2 is desorbed from the absorption solution led to the upper part of the desorption column (12) to form a gaseous CO 2 concentrate, which is removed from the upper part as the absorption solution flows to the lower part of the column (12), from which it is re-circulated to the upper part of the absorption column (11); the CO 2 concentrate obtained is brought to a high pressure, and most of the concentrate's CO 2 is liquidized. In the process, the CO 2 is transferred from the normal-pressure combustion gas using a nearly reversible absorption and desorption process, to the CO 2 concentrate at a lower pressure at a temperature near to that of the combustion gas being processed, preferably in the temperature range 35-75°C, in such a way that the absorption and desorption processes take place in columns (11, 12) at more or less the same temperature, preferably without importing external heat to the said processes.
