The... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/air_separation/7387.html Mon, 28 Mar 2011 0:00:00 EDT The Electric Power Research Institute (EPRI, Palo Alto, Calif.; www.epri.com) has signed an agreement with Air Products (Allentown, Penn.; www.airproducts.com) to support the company’s development of a ceramic ion transport membrane (ITM) for air separation. The membrane is being tested and scaled up... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/air_separation/4917.html Wed, 1 Jul 2009 0:00:00 EDT 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 are presented to illustrate the hardware involved. Finally, options for gas supply are summarized and forecasts are made for development in this field. ... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/air_separation/4584.html Sun, 1 Mar 2009 0:00:00 EST 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; www.ongcindia.com). Normally, helium is obtained by liquefaction of all the other... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/air_separation/4180.html Mon, 15 Sep 2008 0:00:00 EDT A pressure-swing-adsorption (PSA) system for hydrogen purification that operates at "tens of cycles per minute," versus one cycle every 4 – 10 min for conventional PSA, will have its first commercial-scale demonstration at an ExxonMobil refinery in France. Developed by QuestAir Technologies... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/air_separation/3574.html Sat, 15 Dec 2007 0:00:00 EST 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... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/air_separation/3500.html Thu, 15 Nov 2007 0:00:00 EST Hollow-fiber membrane tubes that are selectively permeable to oxygen have been constructed by researchers from the School of Chemical Engineering and Advanced Materials at Newcastle University (edlinks.che.com/6899-542), in collaboration with the Chemical Engineering Dept. at Imperial College London... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/air_separation/3348.html Sat, 1 Sep 2007 0:00:00 EDT       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... http://www.che.com/processing_and_handling/liquid_gas_and_air_handling/air_separation/2788.html Wed, 1 Nov 2006 0:00:00 EST
