Since its introduction to the market in 1959, chlorinated polyvinyl chloride (better known as CPVC) has proven suitable for use in a wide variety of chemical process environments. Because it is inert to most mineral acids, bases, salts…
Construction is underway on what is said to be the world's largest hydrogen chloride recycling plant, for Bayer MaterialScience AG (BMS; Leverkusen, Germany; edlinks.chemengonline.com/6517-536). When the unit starts up in 2008 at the Shanghai, China site, it will produce 215,000…
Since February, Lonza Singapore Pte. Ltd. has been using a new I-400 catalyst in a Isomar unit at its Singapore plant, which produces pure isophthalic acid (an intermediate for making resins). The I-400 catalyst was developed by UOP LLC (Des…
The U.S. Defense Advanced Research Projects Agency (Arlington, Va.) has awarded $5.7 million to a two-company consortium to develop an inexpensive and energy-efficient process for making titanium metal powder. Such powders can be used to make strong, lightweight objects, such…
This versatile pump is a compact contortionist The E8 3/8-in. Mini-Matic pump (photo) weighs just 3 lb but can pump as much as 6.8 gal/min and deliver pressures up to 100 psi. It can be mounted upright,…
Next year, DuPont (Wilmington, Del.; edlinks.chemengonline.com/6516-538) plans to introduce a new family of thermoplastic nanocomposites that yield “substantial improvements” in key, desirable properties. With proper dispersion in a polymer, small amounts of a naturally occurring material form nanoscale reinforcement structures…
ADA-ES, Inc. (Littleton, Colo.; edlinks.chemengonline.com/6516-550) has been awarded a contract from the U.S. DOE to develop an improved process for manufacturing activated carbon (AC). AC is the key chemical used in ADA-ES’s mercury-control technology (CE, December 2004, p. 18) —…
Nanotechnology, in the form of nanomaterials, is already a significant business for the chemical process industries (CPI). One recent study says that this year’s global nanotechnology market is worth more than $10 billion, of which 86% is attributable…
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…
