There are many differences between gas detection systems used for process monitoring and those used for protecting the safety of personnel Some types of gas detectors keep an eye on production processes. Others, relying on a number of different technologies,…
The kilogram is the last of the SI units (International System of Units) still defined by a physical object, rather than defined in terms of universal fundamental constants of nature. However, this will change in November 2018, as a multi-year…
This column is based on “Ethylene Dichloride from Ethylene and Chlorine,” a report published by Intratec. It can be found at: www.intratec.us/analysis/edc-e11a. Ethylene dichloride (also known as 1,2-dichloroethane, as well as EDC and DCE) is by far the most widely…
Petroleum refineries built in the 1960s and 1970s have trouble dealing with the corrosive effects of modern feedstocks. Continuous monitoring of corrosion can prevent process equipment failures Aging assets that are past their original design life are becoming an increasingly…
This article provides guidance for setting up a robust alliance between plant owners and EPC contractors to minimize risk and maximize synergies during complex, capital-intensive projects The most meaningful collaboration pathway among plant owners and engineering, procurement and construction (EPC)…
When it comes to selecting materials of construction, keep in mind the favorable properties of fluoropolymers for corrosive service Since its commercialization in the mid-1960s, polyvinylidene fluoride (PVDF) has been used across a variety of chemical process industries (CPI) sectors…
Effective and efficient process operation requires reliable temperature control. This imposes strict demands on the management of the heat-transfer-fluid (HTF) system. This one-page reference provides suggestions for proper maintenance of heat-transfer fluids. Design features necessary to properly maintain acceptable fluid…
To determine what kind of storage silo is best for your site and your materials, begin by answering the following five questions Selecting a silo for your bulk-solids storage needs isn’t like picking out a pair of socks. It’s a…
This column is based on “Acrylonitrile Production from Propylene,” a report published by Intratec. It can be found at: www.intratec.us/analysis/acrylonitrile-e11a. The highly reactive compound acrylonitrile (AN) contains a carbon-carbon double bond conjugated with a nitrile group. The chemical became important…
Modeling and pilot testing can minimize its impact during natural-gas processing Retrograde condensation (RC) occurs in multi-component natural-gas streams at relatively high pressures (for instance, pressures above 40 barg/580 psig). The presence of condensed liquids in such systems can have…
