Process equipment is usually connected by pipelines through which, if an explosion occurs, fire and pressure can spread very rapidly. Propagating explosions pose increased risks of secondary explosions. The intensity of the explosion in connected vessels is increased by pressure…
The S-4 Series of screw compressors now includes options for the 45- to 75-kW performance range (photo). All models are characterized by quiet, reliable operation and have high efficiency. The compressors generate high free-air delivery at low specific-power consumption. The…
This company’s new digital pressure-temperature sensor (DPTS; photo) is designed to measure subcooling for HVAC-refrigeration applications. The DPTS is a self-contained device that measures pressure and temperature and calculates subcooling based on refrigerant type. It is compatible with safety-group A1,…
Thermal oxidizers can be used for the abatement of a wide range of air pollutants and volatile organic compounds. This article describes the custom design of a thermal oxidizer to treat three different waste streams from a biogas plant A…
Safety is often underestimated when planning, operating and maintaining process-measuring equipment. Sensors with SIL certification, alone, do not make the process safe. It is important to avoid systematic errors during planning, installation and operation The correct installation of a temperature…

Thoughtful design can help reduce safety risks at process plant sites by proactively eliminating possible hazards and modifying personnel behaviors Safety is an important value in any organization, but is particularly important in the chemical process industries (CPI) when the…
The MC-COS multi-control valve (photo) is a fully integrated device consisting of this company’s COS pressure-reducing valve, a separator, steam trap and a motorized actuator. It is designed for steam conditioning, as well as to control either the steam pressure…
Last May, Axens (Rueil-Malmaison, France; www.axens.net) started up the first ethanol-to-ethylene pilot plant based on Axen’s Atol technology with Sumitomo Chemical Co., Ltd. (Tokyo, Japan; www.sumitomo-chem.co.jp). The pilot plant, located at Sumitomo Chemical’s Chiba Works, will produce ethylene from ethanol.…
With proper design, installation, monitoring and maintenance, chemical plant operators can increase the lifecycle of fluid systems — and the bottom line Replacing a fluid system component costs more than just the price of the part itself. It also includes…
