Early this month, this company launched a new generation of hot-water recirculation pumps for large industrial heating systems as well as forced-circulation boilers and district heating systems. The horizontal, radially split single-stage volute casing pumps feature a back pull-out design.…
The E-Blower extends the high-efficiency solution provided by the company’s Delta Hybrid series in the low volume flow range. The new E-Design delivers a reduction of power demand of up to 4%, depending on volume flow and pressure difference, says…
Compressors for specialized chemical process industries (CPI) applications — particularly high-pressure applications (involving large- and medium-sized machines) and those calling for small compressor units — present particular challenges to system designers and operators. This article discusses a variety of engineering…
An inexpensive and scalable composite catalyst that is said to outperform platinum for oxygen reduction in metal-air batteries and fuel cells has been developed by a research team led by professor Jaephil Cho from Ulsan National Institute for Science and…
With a separate algae-based technology, Algal Scientific has invented a sterile fermentation process for making beta-1,3-glucan from algae that has lower costs than those associated with fermenting the molecule with yeast. Beta-1,3-glucan is a polysaccharide that boosts immune-system function in…
Technology developed by Algal Scientific Corp. (Northville, Mich.; www.algalscientific.com) uses algae to remove soluble organics, nitrogen and phosphorous from medium- to high-strength wastewaters in a single step. The technology is an alternative to multistep treatment processes involving the use of…
Conventional hydrogen-based systems designed to store electrical energy (from solar arrays, for example) typically feed electricity to a proton-exchange-membrane (PEM) electrolyzer to generate H2 from water. This H2 is then compressed and stored in a cylinder, or as a metal…
In April, a demonstration plant started up that makes bioethanol from cassava residue — a byproduct of tapioca production. The demonstration plant, located at the cassava starch plant of EBP Ethanol Co. in Sa Kaeo Province, Thailand, is part of…
In the ten years since its first isolation by a pair of physicists, the single-atom-thick carbon allotrope known as graphene has been extolled as a “miracle material” for everything from television screens to tennis rackets to superabsorbent fabrics. What excites…
Adipic acid is a dicarboxylic acid that is widely applied to the production of nylon, polyurethanes, plasticizers and other polymers. Its main use is as one of the raw materials for the manufacture of the polyamide nylon 6,6. In 2012,…
