    摘要： Methods and apparatus for cryogenic distillation of air. In a system of air separation columns, all the air is taken to a high pressure which is 5 to 10 bar greater than a medium pressure. A portion of air, between 10% and 50% of the high pressure air stream, is boosted in a cold booster. This boosted air is then sent to an exchanger and a portion of it liquefies at the cold end of the exchanger. Part of the air is sent to one column of the column system, and another fraction is partly expanded in a Claude turbine. After expansion in the turbine, the air is sent to a medium pressure column, and a liquid stream is withdrawn for one of the columns of the system. The withdrawn stream is pressurized and vaporizes in the exchange line. The cold booster is coupled to either an expansion turbine, an electric motor, or a combination of the two.

    摘要： In a method for producing nitrogen by cryogenic distillation, air containing carbon monoxide is sent to a cryogenic distillation column (5), a flow D of nitrogen is taken from the top of the distillation column, with a CO content less than a fixed value S1, and a flow of nitrogen-rich cryogenic liquid coming from an external source (7) is sent to the top of the column, the flow rate of cryogenic liquid sent to the column being less than a value V if the CO content in the air does not exceed a previously defined threshold (S0), and the flow rate of cryogenic liquid sent to the column being greater than a value V if the carbon monoxide content of the air exceeds this previously defined threshold (S0).

    摘要： Integrated air separation units with a petrochemical process. This invention provides an integrated process and gas treatment process wherein at least one first pressurized gas derived from a first process at a first site is expanded. Using the work generated by the expansion of at least one pressurized gas, a first gas compressor at the first site is driven, operates, and removes compressed gas from the first gas compressor. At least part of the compressed gas from the first gas compressor is sent to a gas treatment unit located at a remote second site. At least part of the compressed gas sent from the first site to the second site is treated in the gas treatment unit. At least one fluid from the gas treatment unit is removed and at least part of the fluid removed from the gas treatment unit is sent to the first site.
