ABSTRACT:
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.
