Your current control system can probably do more than you think. Everybody can agree that diagnostics are a good thing they can identify problems early, and keep the plant running at peak performance. Learn how your existing control systems and analog instruments can deliver diagnostic capabilities, at a fraction of the cost of system or instrument replacements.
More attention to steam systems and trap monitoring provides big benefits. At most chemical plants, plant management and operators face increasing pressures to improve the energy efficiency of their processes, so they should see how they can save on steam.
To make the most of diagnostic equipment used in chemical processing, technicians must stretch their knowledge of control valves and related diagnostic equipment that keeps tabs on valve health and safety.
Increasing interest will translate into far more monitoring applications. The worldwide market for wireless technology will grow 26% annually over the next few years, forecasts the ARC Advisory Group. Vendors are responding and key concerns are being addressed.
Consider a variety of factors to select a unit that comes the closest. What steam traps lack in size, they make up for in numbers. In a typical steam plant, their numbers range from several hundred in a large steam plant to more than 20,000 in refinery or chemical complexes.
A profit-per minute metric can really optimize operations. The chemical industry is discovering that it needs better tools to help capitalize on the products and maximize profits to generate cash faster. It needs a new metric: profit per minute.
Production managers, quality control managers and maintenance engineers alike have encountered weigh cells that never worked properly. Why? Why have so many switched from a supposedly high accuracy load cell solution to old fashioned level probes or sight glasses? This article touches on the worst culprits for problems and how to avoid them.

Design provides improved reliability in a polymer-precursor batch reactor. Sensors must respond quickly and survive a harsh environment. Poor probe reliability can make the difference between a process that makes money and one that doesnt.
Control's Béla Lipták continues his series on control of distillation processes, this time focusing on managing reboiler flow, temperature, feed rate, loading and reflux for economy, stability and safety.
