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…
Powerspan Corp. (Portsmouth, N.H.; edlinks.chemengonline.com/6514-535) is developing a process that uses an aqueous ammonia (AA) solution to capture COâ‚‚ from the fluegas (FG) of power plants. Results from a joint research project with the U.S. Dept. of Energy’s (DOE; Washington,…
Although polymer-based piping systems have been used in the chemical process industries (CPI) for decades, the global market share is only around 10%, says Stephan Schuessler, head of technology and R&D at Georg Fischer DEKA GmbH (GF DEKA; Dautphetal, Germany;…
Professor emeritus Kiyoshi Ohtsuka and his colleagues at the Tokyo Institute of Technology, Tokyo, Japan; edlinks.chemengonline.com/6514-538) have discovered a new process that produces pure Hâ‚‚ from cellulose. The process not only has nearly a 100% yield, but produces no CO…
