A control system is used for controlling the equalization of pressure between absorbing and desorbing reactors. In a first reaction cycle in a desorbing reactor a gaseous reactant is desorbed from a solid sorbent and concurrently in an absorbing reactor the gaseous reactant is absorbed on a solid sorbent. In a second reaction cycle, absorption and desorption are reversed in the reactors and at least a portion of the gaseous reactant desorbed from in the desorbing reactor is transferred to the absorbing reactor in an equalization process under computer control. The computer control may detect the demand on the system and adjust the amount of time for the equalization process to increase the efficiency of the system.
