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…
Sodium-ion monitoring can prevent steam-turbine corrosion Studies have shown that sodium is one of the most significant contributors to corrosion within turbines, and that such corrosion leads to cracking, embrittlement and ultimately, turbine failure. The Orion Ionplus 2111LL low-level sodium…
A new phosphoric acid that contains less than 100 parts per billion of 30 different metal ions is now commercially available from Febex S.A. (Box, Switzerland; edlinks.chemengonline.com/5828-539), the phosphorous specialties subsidiary of CECA Arkema Group (Paris). The new grade of…
Using a diamond anvil cell to create high (up to 50 GPa) pressures, and a laser to create high (up to 2,000 K) temperatures, researchers from Lawrence Livermore National Laboratory (LLNL; Calif.; edlinks.chemengonline.com/5828-543), the Carnegie Inst. of Washington, and the…
