  • SYSTEMS AND METHODS FOR PROCESSING BLACK LIQUOR SOLUTIONS
    Publication number: 20260168171
    Abstract: Systems and methods for concentrating black liquor solutions using pressure driven filtration processes are disclosed herein. The systems and methods described herein integrate multiple unit operations with graphene oxide membranes filtration devices to accomplish concentration of black liquor streams. These systems and methods provide a lower energy, more economical solution than the currently deployed technology of thermal evaporation.

  • HEAT EXCHANGER INTEGRATION WITH MEMBRANE SYSTEM FOR EVAPORATOR PRE-CONCENTRATION
    Publication number: 20250180261
    Abstract: A system for processing a feed includes a membrane system configured to receive the feed and produce a concentrate and a permeate, wherein the membrane system includes an active cooling system, a passive cooling system, or a combination thereof. Further, the system includes a heat exchanger in fluid communication with the membrane system and disposed upstream of the membrane system, such that the feed enters the heat exchanger prior to entering the membrane system, wherein the heat exchanger is configured to cool the feed and heat the concentrate by transferring heat from the feed to the concentrate.
