Plant safety software

DNV Software (Oslo, Norway; edlinks.chemengonline.com/6519-533) and The SimSci-Esscor unit of Invensys (Lake Forest, Calif.; edlinks.chemengonline.com/6519-534) have developed a link between the former’s Phastfx flammable-effects-software module and the latter’s Visual Flow safety-system-design software. The link allows process engineers to quickly and…

Adding palm oil boosts the yield of making petroleum-based diesel

Although there has been big surge in biodiesel production recently, such fuels are not without problems of their own, such as low mileage, poor performance at lower temperatures, and adverse effects on engine components. Also, the production process for making…

Last month, the American Chemical Society (ACS) celebrated its 19th annual National Chemistry Week, a community-based program that aims to communicate how chemistry benefits quality of life. The initiative goes hand-in-hand with the American Chemistry Council’s (ACC’s) “essentialâ‚‚” advertising campaign,…

The Mass Balance

    More and more, it is recognized that business and science are interwoven, and that these disciplines can complement each other to achieve corporate goals. In the chemical process industries (CPI), a noteworthy role is that of engineering in…

Making cement while destroying solid wastes reduces pollution

  Large reductions in the emission of pollutants have been reported in the operation of a novel type of municipal solid-waste treatment plant. A group from the Hong Kong University of Science and Technology’s Dept. of Chemical Engineering (edlinks.chemengonline.com/6518-535) has…

How to boost H2 output from biomass gasifiers

  A promising method for producing hydrogen involves the gasification of biomass with steam. To enhance the concentration of Hâ‚‚ in the ensuing mixture of combustible gases, a carbon dioxide sorbent can be used in situ; calcium oxide is commonly…

Bioethanol

Over the last three years, DuPont (Wilmington, Del.; edlinks.chemengonline.com/6518-552) has been developing technology to break down the complex sugar matrix of corn stover as a means for making ethanol from cellulose in high yield. Although there is more research to…

Fire turns this polymer composite into a rigid protective barrier

A new-type of polymer composite has recently been commercialized by Ceram Polymerik Pty Ltd. (Melbourne, Australia; edlinks.chemengonline.com/6517-533) for passive fire-protection applications. Passive fire protection consists of using a material or structure that confines fires, giving people more time to escape…

Efforts to reduce the cost of Si-based solar cells

Most of today's solar cells are made from silicon wafers cut from blocks of crystals. The wafers are typically 0.2-0.25-mm thick, yet most of the photon-to-electricity conversion takes place in the outermost 0.02 mm of the wafer. In an effort…
