Professor emeritus Kiyoshi Ohtsuka and his colleagues at the Tokyo Institute of Technology, Tokyo, Japan; edlinks.chemengonline.com/6514-538) have discovered a new process that produces pure Hâ‚‚ from cellulose. The process not only has nearly a 100% yield, but produces no CO…
ATMI Life Sciences (ATMI; Hoegaarden, Belgium; edlinks.chemengonline.com/5830-549) and Pierre Guérin SAS (Mauze sur le Mignon, France; edlinks.chemengonline.com/5830-550) have formed an alliance to design, manufacture and market disposable fermentors and bioreactors. ATMI’s proprietary mixing system (which features a paddle integrated into…
Corrosion has the chemical process industries seeing red in their metal tanks and pipelines — and on the bottom line, too. In the U.S., for example, chemical, petrochemical and pharmaceutical producers incur direct costs of $1.7 billion/yr for corrosion, or…
Researchers at Pacific Northwest National Laboratory (PNNL; Richland, Wash.; edlinks.chemengonline.com/5830-537) have developed a ceramic-based coating for steel and superalloys that prevents corrosion, oxidation, carburization and sulfidization, which commonly occur in gas, liquid, steam and other environments. The low-cost, easy-to-apply material…
Nippoh Chemicals Co. (Tokyo; edlinks.chemengonline.com/5830-539), is developing a continuous, vapor-phase process to produce hydroiodic acid as an alternative to the conventional liquid-phase batch process. Over the next few months, the company will test the new process in a 30-m.t./yr pilot…
Although many new biodiesel plants are sprouting up around the world, Perstorp Oxo AB’s (Stenungsund Sweden) 160,000 m.t./yr rapeseed-methyl-esters (RME) facility, now under construction at Stenungsund, will be the first to have a reactor made from duplex stainless steel. The…
Bayer MaterialScience AG (BMS; Leverkusen, Germany; edlinks.chemengonline.com/5830-546) has developed a new process for producing toluene diisocyanate (TDI), a precursor for making flexible polyurethane foam. Without disclosing details, BMS says the process reduces investment costs by 20–30%, and energy consumption by…
Qatar Petroleum (Doha; edlinks.chemengonline.com/5829-542) and Norsk Hydro A/S (Oslo, Norway; edlinks.chemengonline.com/5829-543) have formed a joint venture company, Qatalum, to build and operate what is claimed as the largest, initial-phase greenfield aluminum smelter ever constructed. The smelter will have an annual…
Early next year, Nippoh Chemicals Co. (Tokyo; edlinks.chemengonline.com/5829-532) plans to build a 1,000-m.t./yr plant for producing the pharmaceutical precursor trimethyl orthoacetate (1,1,1-trimethoxyethane). The facility will utilize a continuous-flow, microreactor-based process that Nippoh Chemicals developed in cooperation with professor Jun-ichi Yoshida…
It is now fairly well established that mass- and heat-transfer efficiency, reaction selectivity and yield can be improved using microreactor technology (CE, July 2001, pp. 27–35). But the small channel dimensions (below one square millimeter) that are responsible for the…
