When scaling up new processes involving complex feedstocks, such as biomass, well-defined mixing is key. Guidelines presented here will help to efficiently move biomass hydrogenation reactions from the laboratory to commercial-scale operations One of the most promising pathways to biomass-based,…
As dust collection becomes an integral part of chemical processes, monitoring and other technologies promote efficiency and performance Dust control has always been important in the chemical process industries (CPI) due to the often toxic and combustible nature of the…
Liquid-liquid extraction (LLE) is a separation technique that exploits differences in the relative solubility of compounds of interest (the solute) in two immiscible liquids — most often an aqueous phase and an organic solvent. This one-page reference reviews basic information…
Flow analysis can aid in simultaneously sizing pumps and associated piping systems. The concurrent sizing can reduce wasted energy and improve pump reliability In the chemical process industries (CPI), a variety of incredible process-simulation tools are available to provide greater…
The necessity for precious metals, such as iridium, in water-splitting catalysts is a major challenge in the feasibility of large-scale production of hydrogen using electrolysis. Now, a team of researchers from Rice University (Houston; www.rice.edu) has developed a mechanism for…
Next April, a six-year, €4-million project will begin that aims to develop an electrochemical process to recover halogens (chlorine, bromine and fluorine) from waste products. Funded as part of the CZS Breakthrough program of the Carl Zeiss Foundation (CZS; Heidenheim…
A new recycling process has been developed for scrap polypropylene (PP), a waste stream that is currently underserved by many plastics-recycling facilities. The process, developed by PureCycle (Orlando, Fla.; www.purecycle.com), aims to “wash the plastic molecules” using a series of…
A new electrowinning process is being field-trialed at the Prieska copper-zinc mine operated by Orion Minerals Ltd. (Melbourne, Australia; www.orionminerals.com.au) in South Africa, which will enable the production of valuable products, including calcium, magnesium, iron and others, from contaminated mine…
Covestro AG (Leverkusen, Germany) recently started up the production of Naphthylen-Diisocyanate (NDI) for the Vulkollan raw material at a newly built plant in its Map Ta Phut site in Thailand. The groundbreaking of the plant happened almost exactly two years…
Invista (Wichita, Kan.) announced that INVISTA Nylon Chemicals (China) Co. held the inauguration ceremony for its new adiponitrile (ADN) plant at the Shanghai Chemical Industry Park (SCIP). Being a critical part of INVISTA’s integrated nylon 6,6 value chain, the plant,…
