Caprolactam (Figure 1) is a cyclic amide widely used as a chemical intermediate. The main forms of caprolactam are molten (liquid) and flakes. At ambient temperatures, it is a white, hygroscopic, crystalline solid. Almost all caprolactam is used as monomer…
The Joukowsky equation is often relied upon to determine the maximum possible fluid pressure inside a pipe, but there are certain scenarios where this equation does not return the expected conservative result for overpressurization We engineers love our formulas. Especially…
Physical adsorption phenomena play a critical role in many separation and purification processes, including separations of industrial gases, purification of gases, moisture removal from fluids, water purification and others. Adsorption is a surface phenomenon in which a fluid (gas or…
Reduce costs for purging large-diameter pipes Care is necessary when welding large-diameter pipework in stainless, duplex and chrome steels, nickel alloys and zirconium. When welding such reactive materials, they need to be purged of oxygen before, during and after welding,…
Construction is underway of a prototype system designed to extract natural bioactive product compounds from plants using supercritical glycerin as the extraction solvent. The initial target for the process is to extract cannabidiol (CBD), tetrahydrocannabinol (THC) and other active compounds…
Researchers at the Fraunhofer Institute for Applied Polymer Research (IAP; Potsdam-Golm, Germany; www.iap.fraunhofer.de) have developed a process for embedding active enzymes into plastics. This has been difficult before, since plastics are normally processed at temperatures above 100°C. The technology offers…
The SRMHETRWP-15C (photo) is a rugged, industrial-grade 15-in. sunlight-readable touchscreen. This new model provides many important advantages for use in any automated outdoor system. With super-high visibility and brightness, this model is five to six times brighter than standard screens,…
The ST75 mass flowmeter (photo) provides precision measurement in small lines for the detection of hazardous, non-compliant and costly gas leaks, including the monitoring of seal leakage from gas compressors. It measures air or gases from 0.01 to 559 std.…
The tiltable Dima bag emptier (photo) can improve product intake processes, since less time is needed to clean, inspect or replace parts. The tiltable body enables the Dima to be opened for easy access to areas that are normally difficult…
This company recently launched three filtration inspection packages (photo) centered around offering improved filter availability, better filter performance and longer equipment life. The packages are designed to quickly identify common wear-and-tear issues, such as problems with the plate packs, leakages…
