ABSTRACT:
A process for producing an enriched gas stream substantially continuously in first and second adsorption zones by (a) serially passing co-currently a gaseous mixture containing the gas to be enriched through a first adsorption zone having a primary adsorption column and an auxiliary column under pressure to produce an enriched gas stream; (b) discontinuing the flow of gaseous mixture prior to breakthrough and immediately thereafter equalizing the pressure in the first adsorption zone with the pressure in the primary column of the second zone by substantially simultaneously (i) equalizing the auxiliary column from its outlet to the outlet of the primary column substantially to the same pressure in the primary column of the second adsorption zone, and simultaneously equalizing from the inlet of the primary column of the first adsorption zone to the inlet of the primary column of the second adsorption zone; and (ii) pressurizing the auxiliary column of the second adsorption zone substantially to the same pressure in the primary column of the second adsorption zone; (c) venting the first adsorption zone counter-currently to atmospheric pressure; (d) purging the first adsorption zone; (e) concurrently with steps (c) and (d), pressurizing the second adsorption zone with feed gas mixture to the adsorption pressure and producing enriched product gas from the outlet of said second adsorption zone; (f) pressurizing the auxiliary column of the first zone with enriched product gas and equalizing the primary column of the first adsorption zone with the second adsorption zone pressure and repeating steps (a) through (e).
