In this issue we focus on improvements in process technologies used within the industrial gas industry that are raising energy efficiency and cutting costs. Praxair explains its new process technology for Direct Reduced Iron that uses a variety of fuels...
Recent announcements of domestic air separation unit expansions and builds indicate that 2012 is going to be a busy year for the US air gases markets. Changes in the economic landscape during 2011 have led to an increase in demand...
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...
