Aemetis will implement Mitsubishi ZEBREX system at its ethanol plant in Keyes
Type of post: NEWS IN BRIEF.
Aemetis
will implement the ZEBREXTM
dehydration system developed by Mitsubishi Chemical
Corporation (MCC) at its ethanol plant in Keyes (California). ZEBREXTM
is a cutting-edge zeolite membrane dehydration process that has been installed
in approximately 70 alcohol production plants worldwide. According to the press
release, the change from the traditional Pressure Swing Adsorption (PSA)
dehydration process to the ZEBREXTM technology can reduce energy
consumption in the production of biofuels by up to 25%, increasing production
capacity while reducing the usage of fossil fuel-based energy and lowering the
carbon intensity of ethanol produced at the plant.

dehydration processes (extracted from MCC website)
The Aemetis plant upgrade is the first ZEBREXTM
system installation in North America and is the largest implementation worldwide.
The unit will be designed and fabricated for Aemetis by ICM. It will allow Aemetis
to use significantly less natural gas, reduce carbon emissions by approximately
16,000 tons per year and increase ethanol production, achieving a lower carbon
intensity biofuel.
