Hollow Fiber Membrane for Dehydration of Organic Solvents via Pervaporation
National University of Singapore, Singapore, Singapore
This technology relates to a polymeric hollow fiber membrane for dehydrating C2+ alcohols and possibly, ethylene glycol. This membrane can be fabricated via a single extrusion step. Performance is stable for >300 continuous hours at 80 degreesC. Flux is ~10 kg/m2.h and water concentration in permeate is >95%.
Primary Application Area: Renewable & Hydrogen Energy
Technology Development Status: Prototype
Technology Readiness Level: TRL 3
FIGURES OF MERIT
Value Proposition: Hollow fiber configuration allows smaller footprint compared to existing technologies due to its large surface area to volume ratio. Lower energy requirement compared to azeotropic/extractive distillation. Raw materials and equipment used are available commercially.
