| 20110067444 | Processes and Device for Low Temperature Separation of Air - The process and device serve for the low-temperature separation of air in a distillation-column system includes at least one separation column. A main air stream is compressed in an air compressor at a first pressure and is then purified. A first air stream, which is formed from at least one part of the purified main air stream, is further compressed at a second pressure that is higher than the first pressure. From the further compressed first air stream, a throttling stream and a turbine stream are branched off. The throttling stream is cooled down and liquefied or pseudo-liquefied in a main heat exchanger and is then passed on to expansion equipment. The expanded throttling stream is conducted into the distillation-column system. The turbine stream is cooled down in the main heat exchanger and under an intermediate temperature of the main heat exchanger is conducted into an expansion machine. | 03-24-2011 |
| 20110083469 | Process and Device for Obtaining Liquid Nitrogen by Low Temperature Air Fractionation - A device for obtaining liquid nitrogen by low-temperature air fractionation in a distillation column system for nitrogen-oxygen separation includes a high-pressure column; a low-pressure column; a high-pressure column top condenser which is constructed as a condenser-evaporator and comprises a liquefaction compartment and an evaporation compartment; a low-pressure column top condenser which is constructed as a condenser-evaporator and comprises a liquefaction compartment and an evaporation compartment. A throttle stream is formed by one part of a purified feed air that is liquefied or pseudoliquefied in a main heat exchanger. The throttle stream is expanded, and at least some of the expanded throttle stream is introduced as refrigerant stream into the evaporation compartment of the high-pressure column top condenser. | 04-14-2011 |
| 20120131952 | METHOD FOR RECOVERING A GASEOUS PRESSURE PRODUCT BY LOW-TEMPERATURE SEPARATION OF AIR - The invention relates to production of a pressurized gaseous oxygen product by low-temperature separation of air in a distillation column system, having a low-pressure column and a high-pressure column. A first partial stream of the purified feed air is work-expanded in a first expander, and at least partially introduced into the high-pressure column. A second partial stream is cooled in a main heat exchanger to an intermediate temperature, further compressed, cooled in the main heat exchanger where it is liquefied or pseudo-liquefied, and then introduced into the distillation column system. A third partial stream of the compressed feed air is work-expanded in a second expander. A liquid oxygen product stream, removed from the distillation column system, is brought to an elevated pressure, evaporated or pseudo-evaporated in the main heat exchanger, heated to approximately ambient temperature, and ultimately withdrawn as a pressurized gaseous oxygen product stream. | 05-31-2012 |

| 20130047666 | METHOD AND DEVICE FOR OBTAINING PRESSURIZED NITROGEN AND PRESSURIZED OXYGEN BY LOW-TEMPERATURE SEPARATION OF AIR - The invention relates to a method and device for obtaining pressurized nitrogen and pressurized oxygen by low-temperature separation of air. Compressed and purified feed air is cooled down in a main heat exchanger and introduced into a distillation column system comprising at least one high-pressure column and one low-pressure column. The distillation column system for nitrogen-oxygen separation in addition contains a residual gas column operating at a pressure which is lower than the operating pressure of the low-pressure column.

| 20130139548 | METHOD AND APPARATUS FOR PRODUCING PRESSURIZED OXYGEN BY LOW-TEMPERATURE SEPARATION OF AIR - The invention relates to a method and apparatus for producing pressurized oxygen by low-temperature separation of air in a distillation column system having a low-pressure column and a high-pressure column. All of the feed air is compressed to a first air pressure, at least 4 bar above the operating pressure of the high-pressure column. A first partial stream of the feed air, compressed to the first air pressure, is further compressed in a secondary compressor to a second higher air pressure, before being (pseudo-)liquefied and is introduced into the distillation system. A second partial stream of the feed air, compressed to the first air pressure, is cooled and depressurized in an expander, which drives the secondary compressor. A return stream is branched off from the (pseudo-)liquefied first partial stream, depressurized, heated and then introduced to the first partial stream upstream from the secondary compressor. | 06-06-2013 |
