This month, Borregaard Industries Ltd. (Sarpsborg, Norway; www.borregaard.com) will start up an integrated, pilot-demonstration plant to further develop a new pretreatment process for converting biomass into lignin and fermentable sugars. Located at the company’s R&D Center in Sarpsborg, the pilot…
Failures of piping due to vibration-induced fatigue are a serious problem in the chemical process industries (CPI) and a matter of concern for the safety and reliability of plant operations. Due to the complexity of flow-induced vibrations in pipes, no…
Use these pumps where product containment is important Wilden This company recently announced the availability of its PX800 Advanced Series Stainless Steel AODD Pump (photo). The new PX800 design is center-ported and features a full 51-mm (2-in.) flow path and…
Drilling-mud mixers from this company feature high-efficiency gearboxes designed specifically for agitator service and have configurations for application requirements that are unique to mud-mixing. The advanced impeller technology enhances mixing performance, the company says, and proprietary analysis software is available…
A catalyst in which iron atoms are complexed with the ligand pyridine diimine (PDI) has shown promise as a replacement for high-cost platinum-based catalysts for industrial olefin-hydrosilylation reactions. Developed by the research group of Paul Chirik at Princeton University (www.…
Researches at the U.S. Dept. of Energy’s Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov) are developing a process that makes carbon fibers with customized surface contours from polyethylene-based fibers. The patent-pending technique uses a combination of fiber-spinning and…
The technology surrounding a hydrolysis- and fermentation-based process that is capable of utilizing municipal solid waste (MSW) and biomass waste to produce cellulosic bioethanol at low cost is now available for licensing from its developer, TMO Renewables Ltd. (Guildford, U.K.;…
The growth in use of centrifugal compressors in chemical process industries (CPI) applications in recent decades has been brought about by four factors: 1) advances in dry gas seal technology; 2) modern aerodynamic, rotor-dynamic and thermodynamic knowledge and techniques; 3)…
A novel cold-dry process makes possible the utilization of fine form-factor silicon, such as granules and sand-like fines, in the production of high-purity polysilicon for solar photovoltaic cells and semiconductors, where such fine-grained material would normally have to be sent…
Peristaltic pumps work by compressing a tube against a circular pump housing with rollers on a rotating arm. The fluid that is ahead of the roller gets pushed forward, while new fluid is drawn into the tube by the vacuum…
