NOVELTY - Dehydration of a process stream includes regenerating adsorptive material coating by sending a heating stream through the heat transfer flow passages to remove water to produce a raffinate stream comprising water and ethanol; and then sending the raffinate stream to a first heat sink at a higher temperature than a second heat sink and then to the second heat sink until the adsorption flow passages within the second temperature controlled adsorber are regenerated and the second temperature adsorber then undergoes adsorption.    USE - Method for dehydration of a process stream for producing MFGE.    ADVANTAGE - The method enables an increase in the recovery of ethanol and provides operating flexibility to balance the trade-off between temperature controlled adsorption heat pump performance and water adsorption capacity.    DETAILED DESCRIPTION - Dehydration of a process stream comprises:    (A) sending a fermentation beer stream to a solids separation unit;    (B) separating the fermentation beer stream in the solids separation unit to provide a bottoms stream including solids, and a process stream including ethanol and water;    (C) providing the process stream to a first temperature controlled adsorber that is undergoing adsorption, where the first temperature controlled adsorber has adsorption flow passage(s) containing an adsorptive material coating and heat transfer flow passage(s);    (D) passing the process stream through the adsorption flow passage(s), where water is adsorbed by the adsorptive material coating to produce a motor fuel grade ethanol product stream;    (E) providing a second temperature controlled adsorber that is isolated from the process stream and is undergoing regeneration, where the second temperature controlled adsorber has adsorption flow passage(s) containing an adsorptive material coating and heat transfer flow passage(s);    (F) providing a heating fluid to the heat transfer flow passage(s) of the second temperature controlled adsorber;    (G) regenerating the adsorptive material coating by sending a heating stream through the heat transfer flow passages to remove water to produce a raffinate stream comprising water and ethanol; and    (H) then sending the raffinate stream to a first heat sink at a higher temperature than a second heat sink and then to the second heat sink until the adsorption flow passages within the second temperature controlled adsorber are regenerated and the second temperature adsorber then undergoes adsorption.
