ABSTRACT:
Method for automating and optimizing the phases of the working cycle in adsorption gas dehydration plants of the "heatless" type, having two tanks storing an adsorbing medium and alternating with each other in the regeneration, repressurization, inversion, adsorption and decompression steps. The method according to the invention provides that the repressurization and inversion operations are driven by a single pneumatic pulse of simultaneous control by a programmer providing and removing only one signal at preselected intervals with respect to the servocontrol of an inversion valve, the shutter of which changes over only under the condition of balance between the force or bias of the servocontrol and the differential pressure between the two tanks.
