PROCEDE D'ADSORPTION A MODULATION DE PRESSION AVEC REGULATION |
摘要 |
A pressure swing adsorption process for producing a gas stream enriched in a compound X from a feed gas stream is provided. The process includes at least 2 adsorbers, with each adsorber being subjected to a pressure cycle having a high pressure and a low pressure. The process includes adsorption at the high pressure with production of the gas stream enriched in compound X, depressurization to the low pressure with production of at least one portion of an elution gas, c) elution at the low pressure by means of the elution gas, and repressurization to the high pressure. The pressure cycle has a phase time corresponding to the duration of a pressure cycle divided by the number of adsorbers. The pressure of the pressure cycle is modified to keep the phase time of the PSA equal to or within ±5% of the nominal phase time. |
