Carbon dioxide keeps its cool
Article Abstract:
The consumption of liquid CO2 is expected to grow by 2 to 4% through 2003, according to Barbara Heydorn, senior consultant at SRI Consulting. On the other hand, Bruce Woerner, global CO2 manager at BOC Gases, says the growth is coming from traditional markets that previously did not have the dispoable income to use liquid CO2. Most of the new technology utilize the solvent properties of supercritical CO2. For instance, Messer Griesheim GmbH will commercialize a CO2 process for recycling sludge produced during metalworking.

Souped-up liquid chromatography
Article Abstract:
Rhodia, Daicel Chemical Industries and Catalytica are some of the companies that use liquid chromatography for isolating DNA compounds and chiral compounds. It is currently the method-of-choice and the only available process for separating similar substances or recovering fragile compounds. Bruce Pynnonen, senior chromatography scientist at Dow Chemical, says there are 227 separation trains in use globally, all of them based on the simulated moving bed chromatography.

World pump demand spurred by environmental mandates
Article Abstract:
Global pump sales is expected to reach more $30 billion by 2003. This was estimated by the Hydraulic Institute. Chemical process industries that handle volatile fluids are switching to sealless canned-motor and magnetic-drive pumps because of stricter regulations on fugitive emissions in the US, Europe and Japan. Meanwhile, changing world populations and developments in water-desalination technology are driving sales of centrifugal and reciprocating pumps.
