The new TMP-X2905/X3405 Series of turbo-molecular pumps (TMP) has integrated power supplies and 3,000 L/s class pumping speeds for the semiconductor and flat-panel-display manufacturers. Integrating the power supply into the pump reduces the height of the new pump by 15%…
Optimizing fan performance can help plants reach overall process efficiency goals. The cost of powering fans and ventilators in the chemical process industries (CPI) is significant. For example, ventilation and air-pollution control systems can account for over a quarter of…
Iron ore is traditionally pelletized using the binding agent bentonite to facilitate transport and handling. A new additive for pelletizing iron ore significantly reduces the volume of binding agent required, while improving pellet strength and production output. Developed by Clariant…
The research group of Yasuhiro Uozumi and Yoichi Yamada at Riken (Saitama, Japan; www.riken.jp), in collaboration with professor Audrey Moores of McGill University (Montreal, Que.), has developed a highly efficient catalyst for performing hydrogenation reactions, which are important in the…
Fermenting sugar is at the heart of many bio-based chemical and biofuel processes, but obtaining sugars from cellulosic biomass at low cost is an ongoing challenge. A new process using a reusable solid catalyst is capable of breaking down a…
Researchers from the U.S. Dept. of Energys Joint BioEnergy Institute (JBEI; Emeryville, Calif.; www.jbei.org) have reported the first demonstration of a one-pot, wash-free process for the ionic-liquid pretreatment and saccharification of switchgrass — a leading potential biofuel feedstock. By combining…
AMT International Inc. (Plano, Texas; www.amtintl.com) and LG Chem, Ltd. (Seoul, Korea; www.lgchem.com) have successfully converted an existing sulfolane liquid-liquid extraction (LLE) unit at LG Chem’s Yeosu plant using a new extractive-distillation (ED) process for aromatics recovery. This technology was…
Cement manufacturing is a major source of greenhouse gas emissions due to two factors: carbon dioxide is released when calcium carbonate calcines to lime (CaO) in the cement manufacturing process; and cement kilns are operated at temperatures of 1,500°C, which…
The selective, one-step biocatalytic hydroxylation of benzene to phenol — at ambient pressure and temperature — has been demonstrated by professors Yoshihito Watanabe and Osamu Shoji at Nagoya University (Nagoya, Japan; bioinorg.chem.nagoya-u.ac.jp). The achievement was made using a wild-type of…
Many investigations are ongoing to achieve ammonia synthesis at energy-saving mild conditions instead of the high temperatures and pressures (500°C, 300 atm) required by the commonly used Haber-Bosch process, which consumes more than 1% of the world’s power production. Now,…
