Rare gases, which include krypton (Ke), xenon (Xe), and neon (Ne), are byproducts of air separation units (ASUs) that produce large quantities of oxygen and nitrogen. Historically, to be economically feasible, the rule of thumb was that an ASU must...
Industrial gas producer Messer (www.messergroup.com) has built an air separation plant, the company’s largest in Europe, in Salzgitter, Germany for approximately EUR 50 million. This plant produces 28,000 Nm3 of oxygen per day, 40,000 Nm3 of nitrogen per day, and...
The separation of air into its simplest components is practiced on an industrial scale using cryogenic distillation in addition to adsorption and membranes. The inputs to an air separation unit (ASU) are air, electrical power, and cooling water. The outputs...
