Chementator Briefs

Self-healing adhesives Researchers at Oak Ridge National Laboratory (Oak Ridge, Tenn.; www.ornl.gov) developed a series of autonomous self-healable and highly adhesive elastomers that are fabricated via a simple, efficient and scalable process. The self-healing elastomers demonstrated unprecedented adhesion strength and…

Separate xylene isomers with less energy

Xylene isomers are usually derived from the catalytic reforming of crude oil, and require costly methods to separate them from each other, including distillation, fractional crystallization and adsorption in high-temperature and high-pressure environments. “The separation of xylene’s isomers requires much…

Modular NGL recovery

Honeywell UOP (Des Plaines, Ill.; www.uop.com) has adapted its recycle-split-vapor (RSV) technology for natural-gas liquid (NGL) recovery into a new, modular offering, RSV2, which enables quick retrofitting of existing gas-processing plants with minimal downtime. “The RSV2 technology can increase ethane…

Anaerobic fermentation process using human gut microfauna

Industrial-scale production of protein-rich food additives based on anaerobic fermentation is slated to begin later this year at a former bioethanol site in Minnesota. The facility will use a fermentation process developed by White Dog Labs (WDL; Newark, Del.; www.whitedoglabs.com)…

Sustainable enzyme-based production of macrocyclic lactones for fragrances

Planned commercial-scale production of macrocyclic gamma-lactone molecules using an enzymatic process will supply the flavors and fragrances market with sustainable alternatives to existing processes based on synthesizing petroleum-derived molecules or isolating molecules from natural sources. The synthetic biology company Conagen…

Crystallization: Contributing to Circularity

In a variety of industrial applications, crystallization technologies contribute to the circularity of manufacturing processes and supply chains Crystallization is a major unit operation in the chemical process industries (CPI), typically used for separating and purifying materials in a wide…

The latest generation of titanium tanks

Under contract to a major chemical industry manufacturer, this company’s engineers developed a new generation of titanium tank containers (photo) for highly corrosive dangerous goods. After two years of intensive development work and construction time, two units were brought into…

Humidity and temperature transmitters for hazardous areas

The new Humicap HMT370EX series of intrinsically safe humidity and temperature transmitters (photo) are designed specifically for hazardous and explosive environments. The entire transmitter can be installed directly in explosive areas, up to Zone 0 and Zone 20, with no…

Direct degradation of microplastics in wastewater

Microplastic pollutants in wastewater are notoriously difficult to treat, and can stem from many common sources, ranging from personal-care products to textiles. A new treatment technology developed by a team of researchers from Institut National de la Recherche Scientifique (INRS;…

New check valves designed for urea service

This company recently introduced a new in-line, axial check valve for urea and ammonia service (photo). Standard sizes range from ½ to 6 in. with flanged, butt weld, hub, lens ring or custom connections. This company’s urea service valves may…
