Runaway polymerizations of acrylic monomers can lead to catastrophic fires and explosions in production plants and storage terminals, as well as during transportation. Special chemical products called shortstop inhibitors are used to minimize the likelihood of runaway polymerization reactions. A…
Improved understanding of differential pressure (DP) flowmeter operation, along with best calibration practices, reduces maintenance errors Utilizing an orifice plate installed in a pipe and accurately measuring the differential pressure (DP) to calculate flow is one of most common methods…
Taking a system approach to find the root cause of a problem can be more beneficial than simply replacing a problematic pump. This article explains why We want the best reliability with anything that we work with. In a plant…
Last month, Climeworks (Zurich, Switzerland; www.climeworks.com) started operations of Orca, said to be the world’s first and largest climate-positive direct air capture (DAC) and storage plant. Located in Hellisheiði, Iceland, the Orca plant has a capturing capacity of 4,000 ton/yr…
