Abstract
A gas stream is purified by a TSA adsorption scheme including at least two adsorbers following, in an offset manner, a cycle including an adsorption phase, and a subsequently, a regeneration phase. The regeneration phase includes a depressurization step, a pre-regeneration step and a regeneration step. A gas circulator is used to circulate the gas within the adsorber in the pre-regeneration step in a closed loop while the circulating gas is heated with a heater.
