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 to transfer heat from the process stream to a heat sink using one or more stages of heat pumping. One stage of heat pumping can be achieved during the regeneration process of a temperature controlled adsorber by desorbing the adsorbed water at a thermal condition enabling useful heat recovery. Another stage of heat pumping can be achieved during the adsorption process of a temperature controlled adsorber by transferring the heat of water adsorption to a heat sink. The heat sink with respect to each stage of heat pumping can be a solids separation unit, such as a beer column.
