PRESSURE SWING ADSORPTION METHOD WITH ADDITIONAL ELUTION

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...

description	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; then depressurization; then elution at the low pressure; and finally repressurization to the high pressure. The elution gas is made up fractions of gas stream resulting from the depressurization of an adsorber and the gas stream enriched in compound X. The pressure cycle has a phase time corresponding to the duration of a pressure cycle divided by the number of adsorbers and the fraction of the gas stream enriched in compound X is determined as a function of the phase time.
