Definitions
- EP-A-0.557.935 describes a process of this type, in which the first flow is air to be distilled, the second flow is nitrogen at the medium pressure boosted in booster 110 and third flow is a waste gas expanded in turbine 113 which is coupled to the booster.
- DE-A-28.54.508 describes a process of this type, in which a part of the air is first boosted in the booster then expanded in a turbine coupled to the booster, and then sent to the column low pressure of a double column.
- DE-A-25.57.453 describes a solution to this problem with a process whereby the second flow is a fraction of the first flow, which is the air to be distilled.
- the second flow booster 5 is coupled to a turbine 6 which serves to relax the nitrogen gas at medium pressure (the third flow).
- the prior art then recommends recovering the energy from the turbine on a generator or dissipating energy on an oil brake.
- the invention aims to improve energy performance or reduce the investment costs of these known methods.
- An air flow is sent to a multistage compressor 5 5A, 5B, 5C. After being compressed in the first stage 5A, the flow is divided in two. A first flow is compressed in the second stage 5B. A second flow 2 is boosted by a booster 7 to a pressure close to that of stage 5B and then mixed at the first flow. All the flow of reconstituted air is compressed in stage 5C before being cooled in the exchange line 11 and sent to the distillation column 13, to be there separate.
- One of the products of the separation is a flow of nitrogen 3 withdrawn from the head of the medium pressure column 13 at a pressure of approximately 6 bar.
- a fraction 31 is relaxed to a pressure close to the pressure atmospheric in turbine 9 then sent to the cold end of the line of exchange in which it heats up by yielding its frigories to the flow of air sent to the distillation.
- the turbine 9 is coupled to the booster 7 and so part of the expansion energy is used to boost the second flow air 2.
- the invention could be realized in a installation comprising a single-stage compressor, a booster and a turbine coupled to the booster.
- a single-stage compressor a booster and a turbine coupled to the booster.
- We would compress a first flow of one gas mixture in the compressor and a second flow of a mixture gas in the booster, the two compressed gas mixture flows then being mixed.
- gas mixtures can be gases almost pure and that the gas mixtures compressed by the compressor and the booster do not necessarily have the same composition.
