ABSTRACT:
A twin tower gas drying apparatus in which the towers alternately receive moisture saturated air to be dried and then receive dry air to regenerate the desiccant which had previously adsorbed moisture from the saturated air includes purge valves which release the air used for regeneration of the desiccant into the atmosphere and controls for the purge valves that alternately open and close the purge valve during regeneration so that the tower being regenerated is alternately pressurized and depressurized during regeneration so that the amount of air released through the purge valve is limited without causing a dew point elevation of the dry air.
