Due to the rising costs of water use and disposal, improved treatment technologies make economic sense While chemical processors think of themselves as just that — makers of chemicals — they don’t often consider themselves players in the water industry.…
Bulk-bag discharge unit has low headroom requirements This patented system (photo) is custom designed for the safe discharge of product into the user’s process. It features several stainless=steel features, including the Flo-Lock discharge spout-closure system, which is said to quickly…
Liquid-level measurement in storage tanks or other vessels is important for avoiding spillage and process upsets. One class of technologies for liquid-level measurement involves measuring the pressure exerted on a gage by the weight of the liquid, and this one-page…
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…
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…
