The chemical process industries (CPI) are subjected to countless environmental, health and safety (EH&S) regulations affecting the production, distribution and general use of chemical products. To add to the existing burden, new global initiatives related to product stewardship — most notably REACH and GHS (see box, Regulations 101, below) — are joining the regulatory fray. "REACH and...

A system for controlling oxides-of-nitrogen (NOx) emissions from catalyst regenerators in fluid catalytic crackers (FCCs) has cut NOx output to below 40 ppm (and as low as 25 ppm under certain conditions) in its first commercial installation, according to its developer, Shell Global Solutions (Houston, Tex.; edlinks.che.com/7373-531). This compares with about 20 ppm for selective catalytic reduction (SCR)...

After several years of proven operation in the food- and nutritional-products industry, a patented drying technology is now ready to be applied for any liquid or slurry product. Developed by MCD Technologies, Inc. (Tacoma, Wash.; edlinks.che.com/7373-535), the Refractance Window (RW) system is said to cost about one third as much as freeze drying equipment, and consumes about one third to half the energy...

Infrared (IR) analyzers are widely used for gas, liquid and surface analysis. Up to now, the most common and inexpensive IR sensor has been a combination of filters (non-dispersive IR) — which have a restricted wavelength band — with a pyroelectric detector; alternatives, such as Fourier transform (FTIR) spectrometers, require an elaborate optical configuration and tend to be expensive. Now, an...

Petroleum refiners can have the option to produce more diesel fuel or propylene from their fluid catalytic crackers, depending on the demand, through a new process offered by Shell Global Solutions (edlinks.che.com/7373-541). The process enables a typical FCC (processing a large percentage of residual feed) to produce up to 19.3 wt.% light cycle oil (LCO, for diesel fuel) with 10 wt.% propylene, or about...
