On December 11, 2017, we finished zeolite membrane separation system for dewatering of ethanol with scale of 100,000 T/a. The produced anhydrous ethanol meet with the requirements of GB/T678-2002 standard. The zeolite membrane used in the separation system was synthesized with microwave heating which was first developed by our group in 1999. This separation system is the largest zeolite membrane facility in the world.
