Properly specifying process control valves for a plant project is critical to achieving efficient and effective processes. This one-page reference discusses key considerations for specifying control valves. Valve specification Process engineers should take the following aspects into consideration when specifying…
Using a vast collection of experimental distillation-column data, sieve tray stability, and its influence on efficiency, are explored in terms of several physical and mechanical properties For trayed distillation columns, the concept of tray stability was introduced by the author…

This company’s line of multi-purpose pressure gages (photo) includes models designed for use with gas, oil, water and other media not corrosive to brass or bronze. There is also a dedicated device designed specifically for anhydrous ammonia applications. Gage options…
ParallelPro (photo) is a leveling tool designed for chemical-vapor-deposition (CVD) processes, or any equipment requiring precise parallelism. Equipped with wireless communications and a field-serviceable battery pack, the ParallelPro measures offset distance, parallelism and temperature. Measurements are transmitted via Bluetooth to…
This practical guide provides information on proven backwash-tuning techniques that will improve the reliability and robustness of sand filters in water treatment applications Water is a fundamental part of virtually all plants in the chemical process industries (CPI). Examples of…
Branson MCX Series cleaners (photo) are ultrasonic systems purpose-built for cleaning plastics injection molds. They feature side-mounted, immersible transducers and powerful immersion heaters that can provide fast and efficient cleaning. Since most plastic injection molds are rectangular, with a lot…
Flow Detective Plus (photo) is an electronic airflow-meter calibrator designed to measure the flow of air-sampling pumps to within 2% accuracy. It can calibrate within the airflow range of 20 to 5,000 mL/min to ensure correct flow. Compatible with this…
The MAN-LC (photo) is said to be the only digital pressure gage available with IO-Link. The device includes two configurable outputs that form part of a standard instrument and may be custom-programmed by users as desired. The display screen features…
DetaPipe (photo) is a new high-performance clad-metal pipe product designed for use in corrosive, high-temperature processing environments. DetaPipe is produced using a proprietary process that joins corrosion-resistant alloys, such as zirconium and titanium, to lower-cost, base metals, such as carbon…
