Abstract: Method for drying a gas by feeding the gas into a series of at least two chambers containing each a regenerable adsorbent for drying said gas and meanwhile to feed a part of the dried gas into a series of at least two other chambers while those other chambers are vented, in order to regenerate the adsorbent contained into these two other chambers. Meanwhile, a blower feeds air from an air intake into at least one of the at least two other chambers in order to improve the regeneration of their adsorbent. An apparatus that is adapted to implement the method, is also disclosed.
