Sacrificial Protective Coating Materials that can be Regenerated In-Situ to Enable High Performance Membranes

Among the various manufacturing processes employed across all U.S. industries, the process of concentrating weak black liquor (WBL) in the pulp and paper industry is identified as one of the largest energy reduction opportunities for separation technologies. The concentration of WBL in the pulping process is currently performed by multiple stages of steam-heated evaporators, which concentrate the liquor from approximately 15% solids to about 65%–80% solids. This process consumes large amounts of energy due to the high heat needed to vaporize water.
