Global Air-Pollution Regulations: Variation is the Norm

The chemical process industries (CPI) are, by their very nature, global in scope. While chemical process operators share many common aspects (in terms of the use of chemical engineering unit operations), the location of their operation brings about different requirements…

Organic corrosion inhibitors perform well against oxidizing biocides

After extensive pilot- and field-testing, U.S. Water Services (St. Michael, Minn.; www.uswaterservices.com) plans to roll out new “green” corrosion inhibitor products, which have been tested not only for effectiveness against corrosion in cooling-water applications, but also for the inhibitors’ performance…

Optimized carbon-adsorbent material for natural gas storage

Techniques for manufacturing carbon adsorbent materials with highly tuned pore properties have been developed by EnerG2 Technologies Inc. (Seattle, Wash.; www.energ2.com). The technology platform produces carbon adsorbents that enable the storage of natural gas at significantly lower pressures than those…

A self-cleaning electrolytic cell that converts waste streams into disinfectants

Dealing with wastewater streams in petroleum refineries and petrochemical operations is often a trying task — environmentally, economically and logistically — especially as regulations on salinity in waste streams are tightened. However, many waste streams actually contain useful components, such…
