Flowmeters

    These meters have no moving parts The Vortex PhD (photo) is an inline meter that measures flow of liquids, gas or steam. With a fully welded sensor construction, the Vortex PhD has no moving parts nor holes that…

A completely new design for mag-drive centrifugal pumps

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…

Tiny Fe-Ni batteries accelerate soil decontamination

Soil contaminated with chlorinated aliphatic compounds can be remediated ten times faster than with biological or iron-based methods by use of a new metallic powder developed by Tosoh Corp. (Tokyo; edlinks.chemengonline.com/6514-532). The powder, called MA-FN20, electrochemically strips the chlorine atoms…

Harvesting vibrations to power devices

Vibrations from rotating equipment are routinely analyzed for condition monitoring. Now, the vibrational energy can also be “harvested” and used to power wireless and battery-free devices capable of sending large amounts of data from industrial equipment, using a microgenerator developed…

NH3-based CO2 capture to be field tested

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,…

A multiport valve enhances countercurrent ion exchange

PuriTech (Dessel, Belgium; edlinks.chemengonline.com/6514-536) has developed a continuous ion-exchange system, called Ionex, which uses up to 75% less water and requires about half the volume of ion-exchange resin, compared with traditional fixed-bed systems, says PuriTech projects director Filip Rochette. Ionex…

Plastic pipe proves itself after three years of service

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;…

Making pure hydrogen from biomass

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…

New polymers improve the repair of knee cartilage

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,…

New olefin-block copolymers

Dow Chemical Co. (Midland, Mich.; edlinks.chemengonline.com/6514-541) has launched Infuse olefin-block copolymers (OBC), a new family of olefin elastomers, which deliver improved properties (including abrasion resistance and high-temperature performance), and processing capabilities (such as faster set-up in processing for reduced cycle…
