New innovations in temperature sensors, calibration and associated equipment are helping to keep plants operating reliably and safely Temperature is one of the most important process parameters that needs to be measured and controlled in the chemical process industries (CPI).…
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…
Managing the risk from combustible dust explosions involves a number of strategies for preventing explosions, as well as isolating, venting and suppressing explosions if they occur. Complying with applicable NFPA standards is a pathway toward minimizing risk Combustible dust explosions…
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…
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,…
The Pascal CV4 pressure transmitter (photo) has a high-resolution graphic display with backlighting. The device meets all typical requirements for pharmaceutical processing. Its high accuracy enables precise dosing in the filling process so that valuable product is not lost. The…
Extracting Li Doosan Heavy Industries & Construction, Ltd. (Changwon, South Korea; www.doosanheavy.com) has developed technology for recovering lithium carbonate from waste batteries. Li2CO3 is a key material that is used in batteries in electronic devices, such as laptops and mobile…
Following a standardized project-development process, in combination with a robust cost-estimate classification system, can help to ensure that projects meet their financial goals Cost estimating is critical to support decision-making during the project development process for projects in the chemical…
Plant Watch Huntsman to increase ethylene carbonate production capacity June 14, 2021 — The Performance Products division of Huntsman Corp. (The Woodlands, Tex.; www.huntsman.com) is planning to significantly increase existing production capacity for ethylene carbonate at its Conroe, Texas facility…
Although the oceans contain about 5,000 times more lithium than what is found on land, the low concentrations (about 0.2 parts per million (ppm)), as well as the predominance of other larger ions (sodium, magnesium and potassium) makes Li extraction…
