A new explosion-isolation device with patented features
The Interceptor-QV explosion-isolation device (photo) uses a patented system where a differential pressure switch continuously monitors the pressure drop across the mesh cartridge, alerting operators if buildup of dust occurs on the mesh. The core feature of the Interceptor-QV is…
Protecting Steam Systems from Corrosion
Steam and condensate-return systems can be susceptible to unique forms of corrosion. This overview explains how to prevent or minimize such issues Steam is utilized for process heating and other applications at thousands of industrial plants in the chemical process…
Facts at your Fingertips: Temperature and Rupture Disk Burst Pressure
Rupture disks are non-reclosing pressure-relief devices that protect vessels, such as reactors, from damaging over-pressurization (or vacuum) conditions. Temperature can affect rupture-disk burst pressures in ways that users should understand before ordering them (Figure 1). This one-page reference provides an…
Area Electrical Classification in Research Applications: Is It the Only Mitigative Choice?
Area electrical classification is a powerful tool for process safety. It is not, however, the only viable approach to a safe process Electrically classifying an area is a long-standing safety measure in the petrochemical and related industries. It is also…
Unlock the Energy Potential of Your Plant
By exploring strategies for process integration, such as waste-heat recovery and combined heat and power generation, plants can significantly improve their energy efficiency and reduce utility costs In a chemical processing plant, utility costs typically account for about 10 to…
