Liquified DME cuts energy costs for dehydrating solids

A dehydration process — which uses about half the energy required by thermal methods for drying brown coal or sludge — is being developed by the Central Research Institute of Electric Power Industry (Tokyo, Japan; edlinks.chemengonline.com/6897-532). The process uses liquefied…

Putting MgH2 in your fuel tank

Techno Bank Co., Ltd. (Tokyo, Japan; edlinks.chemengonline.com/6897-537) has developed a new supply, storage, and transport system for safely handling a high capacity of hydrogen in fuel-cell applications. The system — a cassette containing nano-sized powder of magnesium hydride (MgHâ‚‚) —…

High-speed reactor willspin out biodiesel fuel

  A high-shear reactor that is said to accelerate chemical reaction rates by up to three orders of magnitude will get its first commercial tryout in the production of biodiesel fuel. Kreido Biofuels, Inc. (Camarillo, Calif.; kreido.com), the reactor's developer,…

A new PSA process to recover high-purity H2 from steam reformers  

Kobe Steel Ltd. (Kobelco; Tokyo; edlinks.chemengonline.com/6896-532) has developed a process to recover hydrogen from methane steam reformers with purity that is sufficiently high for use in fuel cells. The key to the process is a proprietary carbon-monoxide adsorbent for Hâ‚‚…

Energy Management: Consider Supply And Demand

    It's no secret that the chemical process industries (CPI) are being significantly impacted by the recent increases in energy costs. According to the U.S. Department of Energy, the CPI's percentage of total operating costs that are attributable to…

A step closer to a next-generation, renewable diesel fuel

ConocoPhillips LP (CP; Houston, Tex.; edlinks.chemengonline.com/6896-539) and Tyson Foods, Inc. (Springdale, Ark.) have formed an alliance to use beef, pork and poultry by-product fat to create renewable-diesel (RD) fuel that burns cleaner than conventional diesel. The production technology uses a…

Minimizing Flame Impingements In Fired Heaters

    Fired heaters are used considerably in the chemical process industries (CPI), for heating crude oil in the petroleum refining and petrochemical sectors. Unfortunately, fired heaters are often taken for granted and neglected more than other equipment in terms…

This coal-gasification process produces H2- and CO-rich syngas in separate streams

A coal-gasification reactor that resembles a metals smelter and operates in two cycles (oxidation and reduction), alternately producing hydrogen and syngas, is being developed by Diversified Energy Corp. (Gilbert, Ariz.; edlinks.chemengonline.com/6895-536) and Alchemix Corp. (Carefree, Ariz.). In the oxidation cycle…

The cost for concentrating ethanol may drop thanks to a membrane that acts like a valve

In order to produce ethanol with nearly 100% purity from fermentation broth, conventional processes use a two-step distillation operation, which accounts for almost 55% of the total energy requirements. Therefore, improving the concentration step is a key to reducing the…

Flexible battery  

A paper-thin battery, with an electrode made from a redox-active organic polymer film (200 nm thick), has been designed by researchers at Waseda University (Tokyo; edlinks.chemengonline.com/6895-547). The polymer has nitroxide-radical groups that act as charge carriers. According to professor Hiroyuki…
