End-of-life and other product stewardship initiatives will impact chemical plants. An agreement to lessen the environmental impact of chemicals production will have global ramifications. Meanwhile, European end-of-life directives on electrical and electronic equipment already are having a worldwide effect.
When it comes to selecting and sizing control valves and positioners, this article not only helps you pick the right one for the right job, but also includes a valuable valve selection chart you can download!
Things are changing at warp speed. Manufacturing companies are collecting large volumes of data from data systems but improvements are possible only if the data are analyzed and developed into useful business parameters.
Industry faces the threat of draconian demands from Congress as chemical plants remain an attractive targets for terrorism attacks, according to Mark Rosenzweig, editor in chief of Chemical Processing.
Theres more to boiler level control than measuring level and adjusting a feedwater valve. Improved measurements and inverse response are just a few of the influences on operating boilers in a reliable manner.
The new sampling/sensor initiative (NeSSI) is moving steadily to fulfill its original promise of increased efficiencies, costs-savings, and micro-analytic capabilities despite recent growing pains related to fieldbus.
The more energy prices rise, the more heat integration saves. However, heat integration steps can present complex control problems. Slip-ups in putting control systems in place can make operations nearly impossible. That certainly was the case at one unit using heat recovery.

Profibus-PA and Foundation Fieldbus both reduce cabling cost by sharing wiring among several field instruments. They also save money by reducing the number of instrument interface cards required to connect field instruments to the control system. However, they all save money by being able to use the same field transmitter for a wide range of measured variables.
When processes change and plants need to install any of several types of ultra-high-purity process gases, specifying an appropriate piping system is crucial. Learn about a sound system design that maximizes efficiency, purity and safety.
The compressed air industry is taking a step that will clear the air about the performance of its equipment. For the first time, many compressed air equipment manufacturers will submit their 50 hp to 200 hp lubricated rotary-screw compressors and 200 cfm to 1,000 cfm refrigerated air dryers to an independent laboratory for performance testing.
