The present depicts a process that gives solution the limitations in the capacity of PSA units for an ample variety of gases separation, obtaining capacities that surpasses the normal 110 thousand cubic meters per hour in a unique process and integrated, that do not use a purge step equal or less to the duration of the absorption step. When increasing the purge time in relation to the absorption step, supplying the purge gas for any absorption bed in the train of one or more absorbent beds that simultaneously supply the purge gas to essentially all the absorbent beds that pass by the purge step, a unique train supplying significant increments in the capacity, with a minimum of loses in the recovery or performance. |
