A plasma-based waste-treatment process will be installed in Dow Corning Corp.’s silicon-products-manufacturing plant in Midland, Mich., where it will recycle chemical wastes, help lower the site’s consumption of natural gas by 400-billion Btu/yr and help reduce the plant’s total emissions by 75%. The installation will mark the first use of the technology in a chemical process plant, says...

Click here for full pdf version of this article - includes all graphs, charts, tables, and author information   This fourth in a series of articles* on piping for process plants examines two topics that may, at first, seem to fall outside the scope of chemical engineering — piping codes and the pipe fabrication. Obviously chemical engineers will not be welding pipes together, but understanding the...

A research team from Austria and Sweden have demonstrated that nanowires of a nickel-rhodium alloy exhibit a suprisingly high reactivity to oxygen. Using physical vapor deposition, the researchers have produced quasi one-dimensional rows of Ni atoms on a single-crystal rhodium substrate, which has Rh steps...

    Glass-lined steel equipment is used in a wide range of chemical processes that involve harsh chemicals, including the production of pharmaceuticals, specialty chemicals, agricultural products and polymers. One of the reasons for the attraction is that glass is resistant to attack from most chemicals and to mixtures of corrosive materials. In addition, it has a smooth, anti-stick surface, is...

Linde Gas (Murray Hill, N.J.; edlinks.che.com/6897-538) and partners have developed a high-pressure gas-delivery system that allows coating powders to be sprayed using liquid nitrogen at temperatures that do not melt the powder particles. The system has been optimized to support a new, cold spray gun technology, called Kinetiks 4000, manufactured by CGT GmbH (Ampfing, Germany). Such a system is being...

    Most assets depreciate, losing value over time as a result of wear and tear, age, or obsolescence. Corrosion, like depreciation, results in the often hidden cost of a non-cash expense — measurable in terms of reduced operating life — that reduces the value of assets. Many engineers in the chemical process industries (CPI) see corrosion on a “straight-line basis” in...
