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 |

20130259782 | METHOD AND DEVICE FOR PRODUCING A FLUID ENRICHED WITH CARBON DIOXIDE FROM A WASTE GAS OF A FERROUS-METALLURGY UNIT - The present invention relates to a process and apparatus for producing a fluid enriched in carbon dioxide starting from a waste gas from a ferrous metallurgy unit. | 10-03-2013 |
20130340472 | METHOD AND APPARATUS FOR LIQUEFACTION OF CO2 - In a method for the liquefaction of a gas containing at least 60 mol % of CO2, in order to produce at least one liquid product, a first feed gas is compressed from a first pressure to a second pressure and cooled so as to form a liquid or supercritical flow, at least part of the liquid or supercritical flow is cooled in a heat exchanger in order to form a cyclic liquid at the second pressure, the cyclic liquid is divided into at least two fractions, including an auxiliary fraction, at least one fraction being vaporized in the exchanger by means of heat exchange with the liquid or supercritical flow part, and where there are at least two fractions, each one is vaporized at a different pressure, and the at least one gas formed is then compressed and mixed with the first feed gas, the auxiliary fraction either forming the liquid product or one of the liquid products, or being treated by separation at a sub-ambient temperature in at least one separating means in order to form the liquid product. | 12-26-2013 |
