At the Chem Show last month (New York; Oct. 30 – Nov. 1), Resodyn Acoustic Mixers Inc. (Butte, Mont.; edlinks.chemengonline.com/6902-531) demonstrated its new, impeller-free mixing technology, which induces microscale turbulence through the propagation of acoustic waves. Dubbed ResonantAcoustic Mixing (RAM),…
A pressure-swing-adsorption (PSA) system for hydrogen purification that operates at "tens of cycles per minute," versus one cycle every 4 – 10 min for conventional PSA, will have its first commercial-scale demonstration at an ExxonMobil refinery in France. Developed by…
Ethanol production is an energy-intensive process in which about 50% of the cost is for distillation and dehydration of the ethanol. A membrane system that does the same job, but reduces the energy consumption by up to 50%, has been…
Japan Oil, Gas, & Metals National Corp. (JOGMEC; Kawasaki; edlinks.chemengonline.com/6902-534) and six private companies have established a research consortium to build a confirmation test-plant for a new Japanese gas-to-liquids (JGTL) process.

The standard temperature range for waste-rubber pyrolysis has been reported as 480 – 1,740ºF. Within 480 – 750ºF, shredded tire scrap decomposes into increasing amounts of gases and oil; and above 750ºF, oil and solid char yields can decrease relative…
The amount of crude oil remaining in depleted oil fields has been estimated to be about 50 – 80% of the total estimated oil reserves. In the past, CO2 has been injected into such wells for enhanced-oil recovery — a…
A plastic membrane that allows CO2 and other small molecules to move through its pores while largely preventing the movement of larger molecules like CH4, has been developed by a team of researchers from CSIRO Materials Science and Engineering and…
