    摘要： Process and installation for the production of gaseous oxygen and/or gaseous nitrogen under pressure, of the type in which air is distilled in a double distillation column (11) comprising a low pressure column (13) operating under a so-called low pressure, and a medium pressure column (12) operating under a so-called medium pressure. All the air to be distilled is compressed (in 1, 3, 7)to at least one high air pressure substantially greater than the medium pressure, and the compressed air is cooled to an intermediate temperature, and a portion of it is expanded in a turbine (8) to the medium pressure, before introducing it into the medium pressure column (12). The air which has not been expanded is liquefied, then introduced after expansion (in 20, 21), into the double column. At least one liquid product withdrawn from the double column is brought to the production pressure, and this liquid product is vaporized by heat exchange with at least one portion of the air to be distilled in the course of cooling. An additional cycle fluid withdrawn from the double column (11) or destined for this latter, is reheated, compressed (in 3; 30, 31) to a high cycle pressure, cooled, a fraction thereof expanded (in 8; 35) with the production of external work, and the rest of the compressed additional cycle fluid is liquefied.

    摘要： A process and installation for the production of gaseous oxygen and/or gaseous nitrogen under pressure by distillation of air in a double column (9), which comprises pumping (in 13) at least one liquid product withdrawn from the base of the low pressure column (11), and vaporization (in 8) of the compressed liquid product by heat exchange with the air brought to a high air pressure. All of the air to be distilled is brought to the high air pressure, and the excess fraction of this air is expanded in two turbines in series (5, 6) to the pressure of the medium pressure column (10), the air being partially reheated (in 22) between the two turbines.

    摘要： The invention relates to an apparatus for producing carbon dioxide-rich liquid, which includes a separation unit including a column for physically washing with a solvent and means for cooling a fluid of the separation unit, and a unit for compressing and liquefying a carbon dioxide-rich gas derived from the separation unit, including means for cooling the gas upstream and/or downstream from the compression operation, a single refrigerating cycle using carbon dioxide as the refrigerant, which is suitable for providing frigories to the means for cooling the fluid of the separation unit and to the means for cooling the gas upstream and/or downstream from the compression operation, and means for sending a portion of the liquid from the liquefaction unit to the refrigerating cycle.
