Egg white is one of the most important protein ingredients for the food industry, with a market of 1.6-million ton/yr in 2020 and projected to grow in the future. Searching for sustainable alternatives to animal-based proteins has been of growing…
Honeywell UOP (Des Plaines, Ill.; www.honeywell.com/uop) recently began offering a post-combustion carbon-capture system based on new advanced solvent technology that allows for improved carbon-capture economics for hard-to-abate industries, such as steelmaking, rotary kiln operations (such as cement-making) and natural-gas power…
A new demonstration plant near Bakersfield, Calif. will produce carbon-negative “green” H2 from woody biomass waste, such as agricultural residues from orchard trees and walnut shells. Developed by Mote, Inc. (Los Angeles, Calif.; www.motehydrogen.com), with engineering partners Fluor Corp. (Irving,…
Plant Watch Ascend to build HMD plant in China’s Jiangsu province January 12, 2022 — Ascend Performance Materials (Houston; www.ascendmaterials.com) signed an investment agreement to construct a new hexamethylene diamine (HMD) and specialty chemicals plant in Lianyungang, China in the…
Thermoplastic elastomers (TPEs) are typically copolymers of a plastic and a rubber that have both thermoplastic and elastomeric properties. The best-known TPEs include styrenic block polymers, which contain molecular blocks of polystyrene (which is hard) and polydiene (which is rubbery).…
A new solid form of hypochlorous acid (HOCl) is showing promise as a highly effective antimicrobial agent. PCT Ltd. (Little River, S.C.; www.para-con.com) and Onza Corp. (Denver, Colo.; www.onzacorp.com) achieved what is said to be the industry’s first-ever successful “crystallization”…
Copper-catalyzed electrochemical reduction offers a path for making valuable chemicals, such as ethanol or ethylene, from CO2. However, selectively generating sufficient yields of two-carbon products requires precise manipulation of the microenvironment near the surface to control reaction activity and product…
A team of researchers, led by professor Myoung-Jin Kim, from Korea Maritime and Ocean University (Busan, South Korea; www.kmou.ac.kr), has developed a process that recovers calcium-free magnesium sulfate from seawater desalination brine (SDB). The process, described in a recent issue…
CO2 Separation Conventional DDR-type zeolite membranes are well suited for separating CO2 from different-sized molecules, such as methane, which is present in associated gas or natural gas. However, such membranes are not very efficient for separating CO2 from O2 or…
In lubricated systems, varnish and deposits can form on metal surfaces as lubricant oils degrade, often leading to inefficient operations and equipment failure. There are many chemical cleaning products to break down varnish, but the effectiveness of these compounds in…
