NOVELTY - Dehydrating process stream (110), comprises: separating a fermentation beer stream to provide a bottoms stream including solids, and a process stream; providing the process stream to a first temperature controlled adsorber (102), where the first temperature controlled adsorber has at least one adsorption flow passage (53) containing an adsorptive material coating and at least one heat transfer flow passage (55); passing the process stream through the adsorption flow passage; generating heat of adsorption; providing a cooling fluid; removing heat of adsorption; and providing heat.    USE - The process is useful for dehydration of a process stream for the production of motor fuel grade ethanol (claimed).    ADVANTAGE - The process comprises recovering heat via heat pumping, which reduces the cost of motor fuel grade ethanol production by reducing the process hot and cold utility requirements.    DETAILED DESCRIPTION - Dehydration of a process stream (110) for the production of motor fuel grade ethanol (MFGE), comprises: separating a fermentation beer stream in a solids separation unit to provide a bottoms stream including solids, and a process stream including ethanol and water; providing the process stream to a first temperature controlled adsorber (102) that is undergoing adsorption, where the first temperature controlled adsorber has at least one adsorption flow passage (53) containing an adsorptive material coating and at least one heat transfer flow passage (55); passing the process stream through the adsorption flow passage, where water is adsorbed by the adsorptive material coating to produce MFGE product stream; generating heat of adsorption in the adsorption flow passage; providing a cooling fluid to the first temperature controlled adsorber; removing heat of adsorption by passing a cooling fluid through the heat transfer flow passage to produce a heated cooling fluid; and providing heat from the heated cooling fluid to a heat sink.    DESCRIPTION OF DRAWING(S) - The figure shows simplified process flow diagram of processes for producing motor fuel grade ethanol utilizing temperature controlled adsorbers and heat pumping of the associated heat of water adsorption.
