Severe service valves (SSVs) differ from general purpose valves in important ways. Presented here is guidance on how to increase service life, reduce costs and improve safety and environmental performance of SSVs Severe service valves (SSVs) are often identified by…
This mature technology can be used to save energy, generate revenue and reduce emissions With the Paris Agreement entering into force last November, the Parties to the Convention established their goals to implement measures to reduce the amount of greenhouse…
This column is based on “Ammonia Production from Natural Gas – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/ammonia-production-cost. Ammonia (NH3) is among the most important industrial chemicals, produced by reacting nitrogen and hydrogen in…
An effective Integrity Operating Window (IOW) program — which establishes safe operating limits and acceptable limits of process variation before an asset begins to degrade — can help operators stay ahead of potential repairs and reduce risk A comprehensive asset-integrity…
The Parat 4920 escape-hood respirator (photo) recently received approval by the National Institute for Occupational Safety and Health (NIOSH) for an extended service life of 16 years, provided that the filter is exchanged after eight years. Replacing the filter halfway…
Various heating or cooling options are described here, along with the factors and design parameters that need to be considered. A sample calculation regarding coils is included Tanks constitute important equipment in the chemical process industries (CPI). Various types of…
In order to correctly size pressure relief valves (PRVs), a robust understanding of discharge coefficients for vapor, liquid and two-phase flow is crucial A pressure relief valve (PRV) is used to prevent the pressure in a process vessel from exceeding…
The advantages and limitations of three powder-testing techniques are reviewed here Powder testing is deployed to characterize products including pharmaceuticals, foods, metal powders, powder coatings and cement — at every stage of the product lifecycle. The resulting data-support product development…
The V-AN Series of self-regulating centrifugal pumps (photo) features a control system that independently adapts to changing feedrates, meaning that when media flows into a vessel, the liquid level rises until the inflow and outflow of the vessel balance out…
This new Diagnostic Tool application — available on Apple, Android and Windows mobile devices — is a quick and simple way for users of Control Techniques’ drives to solve any error codes that the drive may show. Built within the…
