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)…
Every five years or so, a call would come in and once again I would be troubleshooting a certain extraction unit in Canada — usually in the dead of winter. This particular unit had a liquid-liquid extractor, a stripper, a…
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…
In testing by an independent laboratory, Superwool Plus high-temperature thermal insulation has been shown to have a thermal conductivity up to 40% lower than comparable insulation products at 1,000°C. The lower conductivity translates to energy cost savings and reduced carbon…
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…
Recovery boilers, in which pulp and paper companies burn spent black liquor from the kraft pulping process to recover and recycle sodium and sulfur, are a bottleneck in many paper mills. The reason is that they operate at their upper…
The Sani-Pallet is designed specifically for handling materials in a sanitary manner. The plastic pallets have no sidewall seams, gaps, holes and other features likely to trap bacteria. These pallets are made with built-in Microban antimicrobial protection to inhibit bacterial…
