Latest Patents

One of Westermann's latest patents is a method and apparatus for purifying low-grade acetonitrile and other constituents from hazardous waste. This innovative process involves the purification of acetonitrile derived from DNA synthesis, HPLC, and pharmaceutical drug manufacturing process wastes. The method utilizes a first distillation column to separate acetonitrile and a first set of impurities from a second set of impurities. The acetonitrile and first set of impurities are drawn as vapor, while the second set of impurities is collected as the column bottoms. The vapor is then condensed and introduced into a second distillation column, where the first set of impurities is further separated from the acetonitrile, resulting in purified acetonitrile collected as the second column bottoms.
