Brelsford Engineering, Inc. (BEI)

The BEI Hydrolysis Process, for conversion of cellulose to fermentable sugars, involves two sequential processing stages for the dilute sulfuric acid hydrolysis of Ligno Cellulosic Biomass Hemi-Cellulose (HC) and Alpha-Cellulose (AC). Following HC and AC saccharification and acid neutralization, the resulting hexose and pentose sugars are clear and suitable for continuous yeast fermentation and the production of ethanol and/or yeast.

The BEI Hydrolysis Process and Reactor System (BEI-HP&RS), at the BEI Pilot Plant Facility, is a tube-in-tube heat-exchanger plug-flow-reactor (TIT-HX-PFR).

The BEI TIT-HX-PRF can be used to dilute acid chemical process any carbohydrate bearing material, including grains, tubers and cellulosic materials from wood wastes, straw, corn stover, bagasse from sugar cane, soft-wood and hard-wood timber wastes, as well as starch from wheat, barley, corn, cassana, potato and sorghum.

The BEI Continuous Carbohydrate Hydrolysis Reactor (CCHR) is conceptually designed as indicated schematically. (Contact BEI) The BEI TIT-HX-PRF CCHR design will be very compact and very suitable to be fabricated and assembled in Modular-Form, at a one-site fabrication facility and for railroad, truck-trailer or seagoing transportation, with subsequent delivery to any carbohydrate hydrolysis processing location, on the continent, or readily shipped overseas. In this way the BEI CCHR cost, by comparison, will be very low, very attractive and saleable as a unit and result in very high ROI and net profits to the producer, seller and buyer-user.
