Successfully scaling up a mixing process involves understanding several important timescale parameters that can impact chemical reactions and equipment performance Many industrial processes are defined by rates. For example, rates of mass and heat transfer, rates of reaction and rates…
This overview presents guidance for the safe design of piping systems that are used for the distribution of hydrogen gas Hydrogen gas is a very volatile fluid that has a high propensity to leak. This is a very dangerous and…
Five innovative technologies have been selected as finalists for the 2021 Kirkpatrick Award for Chemical Engineering Achievement.* The finalists were selected based on three criteria: the difficulty of chemical engineering problems met and solved; novelty of the technology; and evidence…
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…
A catalytic process to selectively break carbon-carbon bonds within the polymer chains of polyethylene and polypropylene could allow the use of waste plastics to make biodegradable surfactant molecules. Researchers led by the Institute for Cooperative Upcycling of Plastics (iCOUP) at…
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…
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…
There are several technologies used in the disposal of landfill gas (LFG). Here are some key elements that can guide engineers in designing an optimized LFG processing plant People generate trash. Trash is stored in landfills. Landfills contain bacteria, which…
Following a successful Front-End Engineering and Design (FEED) study in 2019, Air Liquide Engineering & Construction (Frankfurt am Main, Germany) will continue its partnership with Samsung Engineering to build a methanol production plant for Sarawak Petchem, a state-owned oil and…
