20090078001 | Cryogenic Distillation Method and System for Air Separation - Methods and apparatus for air separation by cryogenic distillation in a double or triple air separation column. The column in the system with the highest operating pressure is said to be operating at medium pressure. All the air to be distilled is pressurized to a high pressure, which is about 5 bar greater than the medium pressure. The air is purified at this high pressure, and a portion of the purified air is cooled in a heat exchange line, while another portion is expanded in a turbine. Part of the cooled air is drawn from the exchange line with a cold booster, which is mechanically coupled to at least one turbine. An energy dissipation device is also provided which is coupled to the turbine not coupled to the cold booster. The energy dissipation device is either another booster, an oil break system, or an electrical generator. | 03-26-2009 |
20090107176 | Integrated Process and Gas Treatment Process - 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. | 04-30-2009 |
