Ethanol dehydration system by SiftekTM polymeric membrane † [Full subscriber]

Ethanol is very important renewable energy to Brazil and several companies are improving their technologies by developing processes to increase the benefits of ethanol compared to fossil sources. The SiftekTM polymeric membrane is a technology that can save between 35 and 70% of energy when compared with conventional processes. The first pilot plant (Tiverton, Canada) operated dehydrating grain-based ethanol from 80–90 wt% ethanol to 99.2 wt%, showing the good performance of the membrane system. With the goal of testing the system in a commercial capacity, a second plant (Chatham, Canada) was built and operated with success, drying grainbased ethanol from…
