Koch Membrane Systems Inc (KMS) has completed a white paper detailing the potential of membrane filtration technology in the production of biofuels. Membrane filtration technology is a tried and proven method used in many industrial process streams that is now being adopted in biofuels production and integrated biorefineries.
New processes building on successful membrane technology used effectively for years in other starch and sugar-based industries may provide biofuel manufacturers with cost-effective solutions. In particular, membrane filtration technology shows promise to improve "second- generation" cellulosic ethanol processes.
KMS Food and Life Sciences group is helping companies utilize membranes to improve bioprocesses, lower overall energy costs and increase valuable product recovery. Membrane use is rising in biodiesel processes where membranes facilitate water reuse, particularly in areas where water is scarce.
Membrane technology shows promise for concentrating and purifying organic acids, commonly used as the base for a variety of new biodegradable plastics. In addition, so-called integrated biorefineries are using a variety of membrane technologies, particularly those that facilitate continuous, rather than batch, fermentation.
Membranes are poised to play a significant role in this important advancement. In the next few years, a number of cellulosic biorefinery pilot and demonstration plants will be placed online using membrane technology in parts of the production process, says KMS.
