The world’s first commercial plant to produce liquid fuels by direct coal liquefaction is now being started up in Majata, Inner Mongolia, by Shenhua Group (Beijing). Designed to produce 25,000 bbl/d of syncrude from 4,300 metric tons per day (m.t./d)…
An innovation that improves the steelmaking efficiency of an electric arc furnace (EAF) by adding calcium carbide to the process has been developed by NuFlux, LLC (Warren, Ohio), a producer of steelmaking fluxes, and Carbide Industries LLC (Louisville, Ky.; www.carbidellc.com),…
Algae offer a ubiquitous, renewable source of oil for fuels and various chemical products ( CE, September 2008, pp. 22–25), but the extraction of oil from the algae cells is an energy-intensive process that involves dewatering and drying the biomass,…
The world’s first demonstration plant combining underground coal gasification and gas-to-liquids (GTL) technologies in the same facility was officially opened on April 22 in Chinchilla, 350 km northwest of Brisbane, Queensland, Australia. The plant is operated by Linc Energy Ltd…
New line of blown film coolers are designed for warm climates The BFC Series of Blown Film Air Coolers offer an increase in blown film productivity, especially in warmer climates or other environments where ambient air temperature rises during the…
Because temperature control is important in any process, a water-cooling system is a common component in chemical processing plants. For facilities located near coastal areas, the tendency is toward the use of seawater instead of river water for cooling purposes.…
Researchers at United Environment & Energy (UE&E; Horseheads, N.Y.) have developed a catalyst for the efficient conversion of algae to biodiesel. The mixed-metal oxide catalyst (comprised of metals that are resistant to corrosion yet reactive) facilitates the transesterification of algae…
Petroleum refiners throughout the world are faced with increasing uncertainty regarding future refining margins, crude prices and project costs. These factors, along with falling demand for refined products, a global recession, and tighter credit markets, are forcing global refiners to…
Nearly 30 years ago (May 6, 1979), U.S. President Jimmy Carter made the following prophetic statement at the inauguration of a solar-thermal water heater installed on the White House roof: "In the year 2000, the solar heater behind me will…
A process that produces hydrogen from coal with close to 80% energy conversion efficiency, plus coproduction of a carbon-dioxide-rich stream for sequestration, is being developed at Ohio State University (Columbus, Ohio; www.osu.edu). This compares with around 60% conversion efficiency for…
