Title:
SYSTEMS AND METHODS FOR DEWATERING A SLURRY THAT INCLUDES LIGNOCELLULOSIC BIOMASS AND LIQUID
Document Type and Number:
WIPO Patent Application WO/2019/014416
Kind Code:
A3
Abstract:
The present disclosure relates to a dewatering systems, and related methods, that are adapted to convey lignocellulosic biomass to separate at least a portion of the water from a lignocellulosic biomass slurry and accumulate the dewatered lignocellulosic biomass. The dewatering system also includes a headspace occupied by a gas that is at a pressure that facilitates transferring the accumulated biomas into a pretreatment reactor having a pressurized headspace. Such a dewatering system can prevent undue mixing and backflow of gas (e.g., steam) from the pretreatment reactor.
