Abstract
Processes for the pumping of various cellulosic feedstock materials that are used to produce an ethanol-containing beer are disclosed. In certain embodiments, the present invention relates to processes capable of pumping highly viscous slurries and/or feedstocks containing high levels of solids in an energy efficient manner, wherein the slurries of feedstocks are utilized in the production of ethanol.
Claims10
A process for the pumping of biomass feedstocks, comprising:
- (a) providing an aqueous slurry of a biomass feedstock;
- (b) pumping the aqueous slurry from step (a) to a solid-liquid separator;
- (c) separating at least a portion of the water from the aqueous slurry from step (b) to provide water and an increased solids biomass feedstock;
- (d) employing the water separated in step (c) for preparing a subsequent aqueous slurry of biomass feedstock;
- and
- (e) processing the increased solids biomass feedstock in a biomass to ethanol conversion plant.
