This process makes freshwater from brine while capturing CO2

A new electrochemical technology for direct-air capture (DAC) of atmospheric CO2 can also produce freshwater from brackish water or brine waste from desalination or wastewater treatment facilities (diagram). The technology, developed by Capture6 (Berkeley, Calif.; www.capture6.org), splits the salt content…

Reducing CO2 emissions from pig iron production

Researchers of Karlsruhe Institute of Technology (KIT; Germany; www.kit.edu) and the SMS group GmbH (Düsseldorf, Germany; www.sms-group.com) have developed a new process to reduce CO2 emissions from worldwide steel production by several hundred million tons per year. It is based…

Recycle any type of magnet from end-of-life products

A new pilot plant is demonstrating a proprietary technology for recycling magnet materials from end-of-life (EOL) products, such as electric motors, automobile parts and hard-disk drives. Developed by Cyclic Materials Inc. (Toronto, Ont., Canada; www.cyclicmaterials.earth), the Mag-Xtract process is said…

Copper-graphene composite could enable more efficient electrical hardware

Composites of copper and graphene have been explored as a way to improve electrical conductivity, but researchers have not been successful at enhancing conductivity with a corresponding reduction in the temperature coefficient of resistance (TCR), and have not been able…

Chementator briefs

CO2 TO METHANOL Last December, Sumitomo Chemical Co, Ltd. (Tokyo, Japan; www.sumitomo-chem.co.jp) started operating a pilot facility for producing methanol from CO2 at its Ehime Works, located in Niihama City, Ehime Prefecture, Japan. The company aims to complete the demonstration…

Process Control: Optimization at the Edge

The key technologies shaping industrial process control all work in tandem to support the ultimate goal of plant optimization Process control technologies are at the heart of all chemical process facilities, providing the foundation for safe and efficient plants. As…

Facts At Your Fingertips: Overview of Reactor Types

Reactors are at the core of most processes in the chemical process industries (CPI) and are broken down most broadly by whether their operating mode is non-flow (batch) or continuous. Each reactor type has advantages and disadvantages depending on the…

Innovations in Pilot-Plant Distillation Process Design

Small-scale distillation processes have specific concerns that are different than commercial-scale distillation. Presented here are several topics, including column internals and column-sizing software, considered from the perspective of pilot-scale distillation The design and operation of laboratory- and pilot-scale columns are…

Heat Pumps: Decarbonizing the Process Industries

As the chemical process industries push to decarbonize their businesses, heat pumps are emerging as a go-to alternative to fossil fuels. Efficient and cost-effective, heat pumps are a rapidly expanding solution for industrial heat demand In the drive to meet…

A Brief Review of Natural Water’s Influence on Scale Formation in Heat Exchangers

Understanding the water chemistry is a first step in preventing heat-exchanger fouling At the two power plants and chemical plant in which this author formerly worked, the fresh-water-makeup supplies (two lakes and an underground aquifer adjacent to a river) all…
