Membrane Separation in Solvent Lube Dewaxing

Membrane separation process in solvent lube dewaxing. Conventional solvent lube dewaxing processes are energy-intensive due to the need for refrigeration. This new process uses an exclusive polymeric membrane material to separate up to half of the dewaxing solvents from the solvent mixture, reducing the need for distillation, cooling, and refrigeration. This reduced waste generation and VOC emissions. The process increases the yield of lubricants while decreasing by-product generation, virgin material extraction, and equipment.
