NOVELTY - Dehydration of process stream involves introducing process stream comprising ethanol and water into a first temperature controlled adsorber having adsorption flow passage(s) containing adsorptive material coating and heat transfer flow passage(s); passing the process stream through adsorption flow passages, where water is adsorbed by adsorptive material coating to produce motor fuel grade ethanol (MFGE) product stream; and providing heating fluid to heat transfer flow passage(s) of second temperature controlled adsorber that is isolated from process stream and undergoing regeneration.    USE - Process for dehydrating process stream for producing MFGE (claimed).    ADVANTAGE - The process can separate water from a mixture of ethanol and water, and enables heat pumping of heat in water vapor desorbed during adsorbent regeneration to a level enabling useful heat recovery. The heat recovered via heat pumping reduces cost of MFGE production by reducing the process hot and cold utility requirements. The hot utility load of beer column is reduced by an amount approximately equal to the water adsorption cooling load plus the useful heat available in desorbed water vapor. The cold utility load of temperature controlled adsorber is reduced by an amount approximately equal to the total heat pumped into the beer column.    DETAILED DESCRIPTION - Dehydration of process stream involves:    (A) separating fermentation beer stream in a solids separation unit to provide a bottoms stream comprising solids and a process stream comprising ethanol and water;    (B) introducing the process stream to a first temperature controlled adsorber having adsorption flow passage(s) containing adsorptive material coating and heat transfer flow passage(s);    (C) passing the process stream through adsorption flow passages, where water is adsorbed by adsorptive material coating to produce MFGE product stream;    (D) providing a second temperature controlled adsorber that is isolated from the process stream, is undergoing regeneration, and has adsorption flow passages(s) containing adsorptive material coating and heat transfer flow passage(s);    (E) providing heating fluid to the heat transfer flow passages of second adsorber;    (F) regenerating adsorptive material coating by removing water to produce regeneration effluent stream; and    (G) providing heat from the regeneration effluent stream to a heat sink.
