Some U.S. oil refineries repair their centrifugal pumps every three years while other refineries enjoy an average repair interval of 10 years. Learn about the highest-performing refineries and other petrochemical companies that have significantly reduced pump failures, and how you can obtain the same results.
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.
Designing equipment for solids is not an exact science. The flows of gases and liquids are generally better understood than those of solids. Most production problems arise from flaws in the design. This article presents questions you can ask yourself to ensure reliable flow in your silo.

High throughput methods are boosting productivity. A survey of member companies by the American Chemical Council (ACC), Arlington, Va., showed that this year the U.S. chemical industry would be spending around 3% more on research and development than it did in 2005.
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.

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.
