摘要:
An apparatus and process for separating air by cryogenic distillation includes a heat exchanger, a column system having at least one cryogenic distillation column, a conduit for supplying the column system with cooled air from the heat exchanger, a storage tank, a conduit for removing a liquid from the column system and sending it to the storage tank, at least one pump, at least one conduit for sending pumped liquid from the outlet of the or each pump to the heat exchanger, at least one conduit connected to the outlet of the pump or at least one outlet of at least one pump and to a column of the column system, said conduit passing directly to the column without passing via the storage tank.

摘要:
In a PSA separation method with compression (C1, C2) of at least one offgas (3), in case of temporary shutdown of one of the compressors (C1, C2), the operating parameters of the PSA unit (S) are changed to increase the outlet pressure of the offgas (3), in order to maintain a production level above 50% with a single compressor (C1).

摘要:
The invention concerns a plant comprising a portion wherein the fluid path (I/O) is deflected and equipped with a distributor with, in series in the downstream direction (O), a first zone (5) with distribution passages (orifices 6) and a second zone (3), typically a grid or fine-mesh sieve forming diffusion passages, the first passages (6) having a total cross-section not exceeding 20% of the surface of the distributor and the second passages having a total cross-section more than 40% of the surface of the distributor. The invention is applicable to gas treatment by adsorption.
