An inaccurately sized or improperly specified filter can undermine an entire high-performance liquid filtration system. There are a dozen key parameters to assess to determine the proper specification.
As pressure rises on plants to improve productivity and equipment reliability levels, seals and gaskets are being called upon to provide even better performance. Their challenge no longer is simply to prevent leaks but also to play an important role in the life-cycle management of the plant.
From large petrochemical units to tiny pharmaceutical pilot plants, day-to-day operations depend upon providing compressed gases in a controlled, safe and environmentally conscious manner. Correct gas handling also can improve process efficiency.
As users become more familiar with gas seal technology and its advantages, gas seals are being applied to a wider variety of applications and equipment than ever before. As the seals gain in popularity know their advantages and disadvantages.
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.
Carefully managing compressed air can save money. Compressed air is often overlooked in energy studies because many people do not fully understand compressed air equipment, their own system, or what it costs to produce compressed air power.

Chemical processors face significant challenges in controlling fugitive emissions. The emissions escape from valves, compressors, pumps, piping components, etc. It is a difficult task, but necessary to avoid penalties and other liability.
