Abstract: A mechanical separation device optionally includes one or more of a housing, a screen a rotary assembly, one or more wash bars and a plurality of nozzles. The screen can be positioned within the housing to separate at least a portion of the liquid medium from the solids. The rotary assembly can be within the housing and can be configured to move the solids and the liquid medium along an axial length of the housing toward the discharge outlet. The one or more wash bars can be within the housing and can be positioned adjacent the screen. The plurality of nozzles can be spaced along the one or more wash bars. The one or more wash bars can be configured to receive a wash fluid and the plurality of nozzles configured to discharge the wash fluid against the screen.

Abstract: A system for producing ethanol comprises a rectifier column that receives a first process stream comprising from about 42% to about 60% ethanol, wherein the rectifier column purifies the first process stream to provide an ethanol product stream that is at least about 90% ethanol, and one or more evaporators configured to evaporate water from a second process stream, wherein the one or more evaporators generate vapor, and wherein at least a portion of the vapor supplies heat energy for separation of ethanol from water in the rectifier column.
