A process and an apparatus are described for drying moist gas, in particular air, in which the moisture is removed from the gas by a desiccant and the desiccant is freed of the absorbed moisture by a hot regeneration gas. In order to improve the energy balance in the drying of moist gas, in particular air, it is provided that the throughput of regeneration gas through the desiccant is controlled as a function of the temperature of the regeneration gas leaving the desiccant. An apparatus suitable for carrying out the process contains a temperature sensor arranged in the regeneration exhaust gas stream, which temperature sensor controls a device determining the regeneration gas throughput through the desiccant.

A process for drying a moist gas by first removing moisture from the gas by passing the moist gas through a desiccant, and then freeing said moisture picked up by the desiccant from the moist gas by passing a hot regeneration gas through the desiccant, the process comprising, heating the regeneration gas to a predetermined input temperature and inputting the heated regeneration gas to and through the desiccant; measuring the temperature of the exhaust regeneration gas that afflues from the desiccant during a last phase of regeneration; adjusting the amount of regeneration gas that is input to the desiccant while maintaining the temperature of the inputted regeneration gas at said predetermined input temperature until the temperature of the exhaust regeneration gas reaches a predetermined exhaust gas temperature and continuing the adjusting so as to maintain the temperature of the exhaust regeneration gas at said predetermined exhaust gas temperature.
