Purification Or Separation Process Using Several Out-of-Phase Adsorbers

A method of purification or separation of a gaseous mixture containing at least two constituents, with a TSA system, wherein said TSA system comprises n radial adsorbers, with n≧4, wherein each adsorber operating in a pressure cycle of duration T, said pressure cycle comprising a production period and a regeneration period, wherein the pressure cycles of all the adsorbers are phase shifted from one another by a phase shift of duration x·Δφ, where 1≦x≦(n−1) and Δφ=T/n.

An installation for purifying and separating a gaseous mixture, comprising n radial adsorbers with n≧4, each adsorber operating in TSA mode and being subjected to a pressure cycle comprising a production period and a regeneration period, wherein each adsorber is fed via one or more pipes which are connected to a source of gas that is to be purified and to a source of regeneration gas and which are equipped with individual valves the opening and closing of which are controlled via a control device, so that the pressure cycles of all the adsorbers are phase-shifted from one another by a phase shift of duration x·Δφ with 1≦x≦(n−1) and Δφ=T/n.
