A new ethylene recovery unit starts up in China  

Last September, on-specification, polymer-grade ethylene was produced by the first grassroots unit to utilize an ethylene recovery technology that was jointly developed by ABB Lummus Global (Bloomfield, N.J.; edlinks.chemengonline.com/6518-537) and the China Petroleum & Chemical Corp. (Sinopec, Beijing; edlinks.chemengonline.com/6518-538). The…

A commercial debut for a process to make silicon for solar cells  

This month, JFE Steel Corp. (Tokyo, Japan; edlinks.chemengonline.com/6517-532) started up a new production plant that produces 100 m.t./yr of solar-grade (SOG) silicon (Si) from crude Si metal. The company also started to design a 500-1,000-m.t./yr plant for making SOG Si,…

Three-phase emulsifying technology makes a better diesel fuel

Researchers at Kanagawa University (Yokohama, Japan; edlinks.chemengonline.com/6517-535) have developed a three-phase emulsification technology for making stable emulsions of diesel-fuel oil in water. Tests with the emulsion (involving a 30-ton truck) show that fuel-combustion efficiency is increased by 10-15% compared to…

Superconductors

The first demonstration of a new high-temperature-superconducting cable was started last month in Columbus, Ohio. The new triax cable - said to provide three times more power-distribution capacity while using half of the superconducting material, compared to previous superconducting cable…

Coal-upgrading process moves closer to commercialization

Brown coal accounts for about half the world’s coal reserves. Although it contains less ash and sulfur than bituminous, brown coal contains more water, which reduces its heating value. To take advantage of this “greener” source of fuel, Kobe Steel…

A fast PSA technology to be trialed at a petroleum refinery

QuestAir Technologies Inc. (Vancouver, B.C.; edlinks.chemengonline.com/6516-534) has received a CDN$2.2-million order from ExxonMobil (Houston, Tex.) for the construction of a prototype H-6200 hydrogen purifier to be demonstrated at an ExxonMobil petroleum refinery. The H-6200 is based on QuestAir’s proprietary Rapid-Cycle,…

A flash-pyrolysis process converts biomass into bio-crude oil

Lurgi AG (Frankfurt; edlinks.chemengonline.com/6516-535) and the Karlsruhe Research Center (both Germany; edlinks.chemengonline.com/6516-536) have signed a cooperation contract to construct a pilot plant for producing liquid fuels from biomass. As the first of three steps, Lurgi will build a €3.76-million pyrolysis…

Solar cells

At the end of July, Renewable Capital Ltd. (London, U.K.; edlinks.chemengonline.com/6516-545) and Konarka Technologies, Inc. (Lowell, Mass.; edlinks.chemengonline.com/6516-546) entered a licensing and joint-development agreement to scale up Konarka’s dye-sensitized solar-cell technology (CE, March 2004, p. 19). Renewable Capital has committed…

BioOil

Last month, DynaMotive Energy Systems Corp. (Vancouver, B.C., Canada; edlinks.chemengonline.com/6516-548) announced the successful completion of an industrial-scale test burn of its BioOil as a replacement for natural gas in the lime kiln of a pulp and paper mill. The testing…
