Exelus Inc. (Livingston, N.J.; edlinks.chemengonline.com/6891-533) has demonstrated the performance of its ExSact solid-acid alkylation process, having achieved over 1,000 hours of pilot-plant operation on an untreated MTBE raffinate feedstock. The pilot-plant testing was performed to prove the robustness of the…
A process that can enrich highly contaminated natural gas has been developed at Eindhoven University of Technology (Netherlands; edlinks.chemengonline.com/6891-531), with support from the Royal Shell/Dutch Group. The device shows promise as a way to utilize the large quantities of natural…
A medium-temperature pyrolysis process that coproduces coal-tar oil and an upgraded coal-char fuel from low-rank coals is being developed by Convert Coal, Inc. (CCI, Mission Viejo, Calif.; edlinks.chemengonline.com/6519-532). The SynCrude-Syncoal (SC2) process was described by CCI president Ebbe Skov at…
Shanxi Jincheng Anthracite Coal Mining Co. Ltd. (China) has contracted Uhde GmbH (Dortmund, Germany; edlinks.chemengonline.com/6519-535) to engineer and supply a methanol-to-gasoline (MTG) plant. The unit will be part of a pilot-scale complex being constructed at Jincheng, Shanxi Provence — about…
The dramatic jump in petroleum and natural gas prices over the recent years has created much impetus to reduce operating costs at chemical process plants. In processes that use either oil or gas for feedstock, such reduction can…
Energy consciousness and environmental awareness have transformed condensate from an inexpensive byproduct of steam distribution to a valuable resource that can substantially reduce operating costs. For process systems that use steam as the heat transfer media, improved condensate…
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…
The process industries are extensive users of energy. But it is now clearly established that a large amount of this energy is wasted, essentially in the form of heat rejected to the environment through gaseous or liquid effluents.…
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,…
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…
