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)…
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…
Many applications require accurate flowrate measurement for air or other gases. Installation requirements, calibration and maintenance are among the factors that must be considered when selecting a flow-measurement technology The measurement of air and other gases in manufacturing plants in…
Shipping and transport of chemicals require specialized packaging to mitigate the hazards that the chemicals may present. Only packages that are certified to have met testing standards issued by the United Nations (UN) Economic and Social Council (New York, N.Y.;…
Drying biosludge from wastewater-treatment plants is complicated by the “sticky phase,” making the practice more of an art than a science. Discussed here are efforts to define the beginning and endpoints of this phase analytically The drying of biosludge from…
Follow this guidance to minimize risk when adding or modifying plant equipment In 2015, construction in the chemical process industries (CPI) soared. Capital spending surged 18.4% and 255 new chemical production projects were announced, according to the American Chemistry Council…
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…
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…
Understanding boiler performance calculations can allow engineers to improve the operation of their facility’s steam system and better engage with boiler-system vendors Chemical plants, petroleum refineries, power plants and cogeneration systems use oil-and-gas-fired steam generators, fluid heaters and waste-heat boilers…
Fluid seals for chemical process equipment are commonly made from a host of elastomeric and plastic materials. Selecting a seal material requires careful consideration of several criteria. Presented here are short descriptions of the major criteria for seal selection and…
