Biomass torrefaction plant undergoing expansion
A biomass torrefaction plant run by New Biomass Energy LLC (NBE; Quitman, Miss.; www.newbiomass.com) is currently undergoing an expansion that will increase its annual production capacity to 250,000 tons of torrefied wood product. The company expects the expansion to be…
A copper catalyst with promise for utilizing CO2 in organic synthesis
Scientists from the A*STAR (Agency for Science, Technology and Research) Institute for Chemical and Engineering Sciences (Singapore; www.a-star.edu.sg) have shown that a copper catalyst can incorporate CO2 into organic molecules under mild conditions, opening the way to an inexpensive, nontoxic…
Renewable surfactant can replace solvents for cleaning
A nonionic surfactant that is derived from renewable chemicals can outperform common solvents in a range of applications, including industrial cleaning, adhesive removal, degreasing, paint and coating removal, and others. The molecule (N,N-dimethyl-9-decenamide), marketed as Steposol MET-10U, is the first…
Demonstration of a new CO2-methanation process
The first phase of a study on the feasibility of producing methane from CO2 has been completed by Hitachi Zosen Corp. (Tokyo; www.hitachizosen.co.jp) and Daiki Ataka Engineering Co. (Daiki Ataka) a subsidy of Hitachi Zosen, in collaboration with PTT Exploring…
The launch of a new bioethylene-production process
Last month, a new bioethanol-dehydration process was introduced by its developers Axens (www.axens.net), IFP Energies Nouvelles (IFPEN; both Rueil-Malmaison, France; www.ifpen.fr) and Total Refining & Chemicals (Brussels, Belgium; www.totalrefiningchemicals.com). Tradenamed Atol, the process is said to be the most profitable…
Centrifugal Pump Maintenance
Optimal functioning of centrifugal pumps over time depends on sound maintenance practices. The following material represents tips and guidelines for routine preventive and protective maintenance for centrifugal pumps. Monitoring A basic maintenance routine for centrifugal pumps should include monitoring of…
Tight-oil Tightrope for U.S. Refiners
North American production of crude oil, driven by a rapid increase in output of “tight oil” from U.S. shale deposits like Bakken and Eagle Ford, is surging. In many, but not all areas, petroleum refiners are incorporating an increasing amount…
Integrally Geared Compressors in the CPI
In an integrally geared centrifugal compressor (Figure 1), several impellers are mounted on the ends of high-speed pinion shafts, which are rotated by a bull-gear. Each impeller’s casing is mounted directly on the horizontally split gear casing. As is the…
A solid chelating ligand for making heterogeneous catalysts
Shinji Inagaki and colleagues at Toyota Central R&D Labs, Inc. (Nagakute City, Japan; www.tytlabs.com) have synthesized an entirely new immobilization support that can be used to recycle and reuse metalo-organic-complex catalysts, which are widely used for the synthesis of pharmaceuticals…
CO2-utilizing electrocatalytic reaction cell demonstrated
Production of monoethylene glycol (MEG) from waste carbon dioxide has been validated in a demonstration-scale reaction cell developed by Liquid Light Corp. (Monmouth Junction, N.J.; www.llchemical.com). The company says the catalytic-electrochemistry-technology platform used to make MEG can also produce a…
