Pervaporation and Vapor Permeation I – 1 – Keynote Tuesday July 15, 8:15 AM-9:00 AM, Honolulu/Kahuku Bioethanol Production Using Pervaporation and Vapor Permeation Membranes I. Huang (Speaker), Membrane Technology & Research, Menlo Park, CA, USA, ihuang@mtrinc.com R. Baker, Membrane Technology & Research, Menlo Park, CA, USA L. Vane, The U.S. EPA, Cincinnati laboratory, Cincinnati, OH, USA Bioethanol production for use as a renewable energy resource is booming driven by climate change concerns and soaring oil prices. Conventional distillation/molecular sieve drying of bioethanol uses about 20% of the energy content of the ethanol produced. Alternative technologies which consume less energy to dehydrate ethanol are of considerable interest to the bioethanol industry. The existing membrane technology for ethanol/water separations uses pervaporation. The first industrial-scale pervaporation unit was installed in Brazil by GFT (now Sulzer Chemtech) in 1982 to dehydrate ethanol from a cane sugar fermentation plant. Despite this early success, pervaporation has not been widely used in bioethanol production, primarily because the membrane modules used were too expensive and were susceptible to slow degradation, leading to excessive replacement costs. In this paper, the application of pervaporation and vapor permeation to bioethanol membrane separations is described. Novel, low energy process designs require membrane modules able to operate at high temperatures with high water concentration ethanol solutions. The requirements for membrane properties are discussed. The processes described showed significant energy savings compared to the conventional distillation/molecular sieve drying process.
