  • Publication number: 20240151445
    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.

  • Publication number: 20220401880
    Abstract: Embodiments described herein relate generally to systems, apparatus, and methods for using graphene oxide-containing membranes for separation and concentration processes. In some embodiments, a fluid component having a first concentration in a fluid mixture can be concentrated using a first distillation process to a second concentration. In some embodiments, the fluid component can be concentrated from the second concentration to a third concentration using a graphene oxide-containing membrane. In some embodiments, the fluid component can be concentrated from the third concentration to a fourth concentration using a second distillation process. In some embodiments, the fluid component can have an azeotropic concentration between the second concentration and the third concentration.
