ABSTRACT:
Systems and processes for dehydration of a process stream in the production of motor fuel grade ethanol (MFGE) can include temperature controlled adsorption of water in the process stream, and heat pumping of the associated heat of adsorption. The process can include providing a process stream (110) including ethanol and water to a first temperature controlled adsorber (102) where water is removed by adsorption to produce an MFGE product stream (114) and an associated heat of adsorption. A cooling fluid can be provided to the first temperature controlled adsorber (102) to remove heat of adsorption and produce a heated cooling fluid (120). Heat from the heated cooling fluid can be provided to a heat sink.
