Technical and specialty gases find use in many synthesis processes and a number of unit operations, in analysis and in plant maintenance. This article outlines applications for gases in fine and specialty chemistry, ranging from synthesis processes and inerting to off-gas treatment and industrial services. For each one, processes and the field of use are briefly explained, and existing technical solutions...

Apilot plant that uses pressure swing adsorption (PSA) to extract helium from natural gas has been started up and is operating successfully in India at the Kuthalam Gas Collecting Station of Oil and Natural Gas Corp. (ONGC; Normally, helium is obtained by liquefaction of all the other components in natural gas, but this is economically impractical for the Kuthalam gas, which contains...

Technology to copolymerize carbon dioxide and propylene oxide (PO) was first discovered in 1960s, but has not been commercialized due to the formation of cyclic propylene carbonate (CPC) by a “back-biting” reaction, which leads to the formation of unstable, low-molecular-weight copolymers. This limitation has essentially been eliminated, thanks to a new catalyst developed by Professor Kyoko...

      The fortunes of many an industrial sector have risen and fallen in the face of fluctuating oil and gas prices. Today, the industrial gas industry’s fortunes are being buoyed — in a roundabout way — by the strong upward trend in oil and gas prices since 2000, and a growing belief that the days of low prices for these key commodities are largely over. Steadily rising...
