This desalination process uses much less energy than RO
An adsorption desalination and cooling (ADC) plant has been implemented at Solar Village near the Saudi Arabian capital of Riyadh, by King Abdulaziz City of Science and Technology (KACST; www.kacst.edu.sa). The project to build the plant resulted from a collaboration…
This alkylation process uses an ionic liquid catalyst
A new alkylation technology that uses ionic liquids as a catalyst has been licensed by Honeywell UOP (Des Plaines, Ill.; www.uop.com), and will be marketed under the tradename Isoalkyl. The technology — developed by Chevron U.S.A. Inc., a subsidiary of…
Recycling textiles into reusable cotton, polyesters and silver
Millions of tons of cotton-polyester-blend material that would normally be discarded in landfills could be recycled using a newly patented method for removing dyes from textiles, separating cotton from fabric blends, and depolymerizing polyesters. The process, developed and demonstrated by…
A microwave-assisted flow reactor for organic synthesis
Saida FDS Inc. (Shizuoka, http://saidagroup.jp/fds_en/) has commercialized a flow reactor that uses microwaves to produce fine chemicals and pharmaceutical intermediates at high temperatures and pressures. The system has been shown to boost productivity by a factor of 3–6 compared to…
Making bio-oils via solvent liquefaction
At a pilot plant near Ames, Iowa, a team of researchers from Iowa State University (Ames; www.iastate.edu) and Chevron Corp. (San Ramon, Calif.; www.chevron.com) has validated the production of bio-oil via a new process technology called solvent liquefaction. Developed by…
Solution mining technique improves potash yields
A new patent-pending solution-mining technique known as SMER (selective mining with enhanced recovery), developed by Innovare Technologies Ltd. (Carlyle, Sask.; www.innovaretechnologies.ca), can increase yields of potash (potassium chloride; KCl) and achieve lower operating and capital costs compared to traditional potash…
The search for salt-tolerant microbes for improved bioleaching
In response to water scarcity and declining grades of ore, the mineral processing industry has been investigating ways to improve processes, such as bioleaching to deal with increased impurity concentrations in process streams. Advantages of bioleaching for low-grade ores, such…
Ethanol from CO2
Scientists at the U.S. DOE’s Oak Ridge National Laboratory (ORNL; Tenn.; www.ornl.gov) have developed an electrochemical process that directly produces ethanol from CO2. The researchers used a catalyst consisting of copper nanoparticles embedded in carbon spikes, and applied voltage to…
Commercial MOFs on the horizon
A partnership between materials company NuMat Technologies (Skokie, Ill.; www.numat-tech.com) and The Linde Group (Munich, Germany; www.the-linde-group.com) is set to bring metal-organic-framework (MOF) materials into the mainstream industrial-gas sector. Touted for their extremely high surface area and adsorption capacity, MOFs…
Plasma oxidation disinfects water without the addition of chemicals
A new technology that uses plasma to kill bacteria and simultaneously oxidize organic material in water systems offers a non-chemical alternative to water treatment in several industry sectors, such as food and beverage, power generation, oil and gas and others.…
