Since the liberalization of the ethanol market in the mid-1970s, KWST has been selling so-called technical alcohol to various manufacturers in the chemical industry. Depending upon the customer specification, the matching grade of ethanol is delivered, mostly in dehydrated form, but also as an azeotropic product. Depending upon the user, various solvents are available for denaturing, such as ethyl acetate, isopropanol, methyl ethyl ketone, tert-Butanol etc. Delivery is usually made in full tankers or rail tank cars. For a relevant need, delivery is also possible via inland vessel.
