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…
This column is based on “Dimethyl Ether Production from Natural Gas and CO2 (Direct Method) – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/dimethyl-ether-production-cost. Dimethyl ether (DME) is the simplest aliphatic ether, containing only two…
Superalloys, also known as high-performance alloys, are considered as materials of construction for process equipment in applications involving high temperatures, highly corrosive environments and those requiring high strength properties. Many commonly used superalloys in the chemical process industries (CPI) use…
There are many regulations surrounding the production of waste at manufacturing facilities. By approaching regulatory practices in a proactive manner, sites can ensure personnel and environmental safety, as well as continuous compliance When it comes to handling hazardous waste in…
Determining moisture levels in solid materials is important for product quality, handling properties and other considerations. Provided here is an overview of direct and indirect methods for measuring moisture in solids Water is ubiquitous and is unusually reactive because of…
Lifecycle cost analysis (LCCA) can be used as a tool for selecting alternatives that add the most value to a project. The methodology for implementing LCCA is described here In the chemical process industries (CPI), identifying optimum process designs challenges…
This column is based on “Isopropyl Alcohol Production from Acetone – Cost Analysis,” a report published by Intratec. It can be found at: www.intratec.us/analysis/isopropyl-alcohol-production-cost. Isopropyl alcohol (isopropanol or 2-propanol) is a colorless and flammable liquid with a strong odor. Isopropyl…
The use of molecular hydrogen is common across the chemical process industries (CPI). Annually, 70 million metric tons of H2 are produced worldwide. Most industrial H2 production currently occurs via steam reforming of methane, but production via water electrolysis is…
Selecting footwear for plant personnel is not a “one size fits all” situation — various factors must be considered to ensure the best shoe for a specific application Chemical manufacturing plants generally have questions about their overall safety protection program,…
Understanding the implications of adiabatic and isothermal flow assumptions is necessary to have confidence in when to use such assumptions Every engineer uses assumptions because every analysis has an overabundance of variables to consider. Often, there are just too many…
