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…
A traditional treatment for damaged knee cartilage is called autologous chondrocyte implantation (ACI), whereby healthy cartilage-forming cells are taken from an undamaged site of the patient and injected to the damaged site. This procedure takes many weeks, during which time,…
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…
Early predictions suggested that solvents would eventually be eliminated from industrial applications because of health and environmental concerns. After a short period of a small decline in solvent use in 1990s, the solvent demand is now growing steadily…
Fluxome Sciences A/S (Lyngby, Denmark; edlinks.chemengonline.com/5830-547) has been granted patents in both the U.S.and Europe for a method to improve bioethanol production by engineering the ammonia assimilation in yeast. By modifying the redox metabolism, it is possible to reduce the…
DuPont (Wilmington, Del.; edlinks.chemengonline.com/5830-553) has demonstrated the ability to print small-molecule OLED (organic light-emitting diode) materials from solution. The printing process is said more scalable to large-display sizes and substantially less expensive than alternative processes, such as vapor deposition. DuPont…
