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…
In late October, Metso Outotec Corp. (Helsinki, Finland; www.mogroup.com) introduced the DRI (direct reduced iron) Smelting Furnace to substitute blast furnaces used in iron- and steelmaking. The furnace was developed to tolerate high-slag volumes, which are problematic for a conventional…
The Scalance XC-/XR-300 (photo) series of Industrial Ethernet switches has been upgraded with a higher port density, which allows many devices to be connected within large network infrastructures. Thanks to their high-bandwidth ports (up to 10 Gbit/s), the new models…
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…
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…
This company has introduced a new manual dumping system with integral conveyor and separate dust collector (photo), which is suitable for dairy powders, pharmaceutical products and contamination-sensitive bulk foods. Designed and finished to 3-A sanitary standards, the system is composed…
This company has developed a new unit that combines metal detection and weighing to streamline product packaging applications, leading to improved reliability, throughput rates and accuracy. The Metal Detector Checkweigher Combo (photo), unveiled at Pack Expo in Chicago, employs a…
LanzaTech, Inc. (Skokie, Ill.) and Sumitomo Riko Company Ltd. have entered into a joint-development agreement to reuse rubber, resin and urethane waste for the production of a key chemical intermediate, isoprene. Isoprene is produced by plants, and along with its…
Sponsored by Well over eight billion tons of plastic have been produced worldwide in the last 70 years, most of it since the turn of the millennium. Careless use of plastic has escalated into a global environmental problem. Unfortunately, the…
