Eliminate contamination with these drive sockets Designed for sterile and critical environment applications, these 1/4-in. drive stainless-steel deep sockets (photo) are manufactured entirely from 17-4PH stainless steel, so no chrome plating is required on the surface. The risk…
Researchers at CSIRO Exploration and Mining (Kensington, Australia; edlinks.chemengonline.com/6515-548) have discovered that a bacterium, called Ralstonia metallidurans, may be responsible for the formation of secondary gold grains in nature. Cultures of the R. metallidurans - identified, using molecular biology techniques,…
Two chemicals producers have recently reaped the benefits of high-throughput-screening technologies, through research collaborations with Symyx Technologies, Inc. (Santa Clara, Calif.; edlinks.chemengonline.com/6515-550). In April, Celanese Corp. (Dallas, Tex.) deployed a new catalyst at one of its vinyl acetate plants. The…
Intelligent selection and specification help to assure getting representative, uncontaminated samples from multiple process lines to a shared analyzer Process engineers rely heavily on analytical instrumentation to ensure product quality. Properly designed systems help prevent contaminated fluids and gases from…
In the pharmaceutical, biotech and food processing industries, ingredients are transported, mixed, heated and cooled assuming the assurance of product purity required by lawmakers and taken for granted by consumers. Integral to the design of fluid-handling systems that…
In widespread use throughout chemical process plants, centrifugal pumps are often employed (and taken for granted) in severe service conditions. Consequently, it is hardly surprising that problems can arise during their operation. A major difficulty facing the chemical…
Merck (see item above) received the Greener Synthetic Pathways Award for discovering a catalytic synthesis for sitagliptin (a chiral β-amino acid derivative), an active ingredient for the company's new treatment for type 2 diabetes, Junuvia. The synthesis generates 220 pounds…
Trends in the worldwide chemical process industries, especially a steep rise in the compression and liquefaction of gases to lower the costs of their storage and transportation, have heightened the engineer's need to have a working familiarity with…
The 135,514 sq.m. of exhibitor booths, plus the 925 tracks, lectures and other conference presentations, that made up the Achema Exhibition-congress presented by Dechema e.V. in Frankfurt this May offered its 180,000 attendees technological wares and information across a remarkably…
Conventional magnetically coupled centrifugal pumps can only survive dry running — if at all — by using costly materials and complicated constructions, according to Christian Wallrodt, sales manager at Wernert-Pumpen GmbH (Mülheim an der Ruhr, Germany; edlinks.chemengonline.com/6514-531). Such pumps’ bearings…
