Recovering and purifying byproduct and waste ethylene glycol
GlyEco Inc. (Phoenix, Ariz.; www.glyeco.com) has developed a process for recovering and purifying ethylene glycol from a number of industrial byproduct and waste streams so that it meets an ASTM International (West Conshohocken, Pa.; www.astm.org; formerly American Society for Testing…
Global Air-Pollution Regulations: Variation is the Norm
The chemical process industries (CPI) are, by their very nature, global in scope. While chemical process operators share many common aspects (in terms of the use of chemical engineering unit operations), the location of their operation brings about different requirements…
Organic corrosion inhibitors perform well against oxidizing biocides
After extensive pilot- and field-testing, U.S. Water Services (St. Michael, Minn.; www.uswaterservices.com) plans to roll out new “green” corrosion inhibitor products, which have been tested not only for effectiveness against corrosion in cooling-water applications, but also for the inhibitors’ performance…
February Chementator Briefs
Cellulose nanocrystals New research from Purdue University (West Lafayette, Ind.; www.purdue.edu) has shed some light on the physical properties of cellulose nanocrystals. The nanocrystals, which are about 3-nm wide and 500-nm long, have historically been difficult to analyze, but…
Optimized carbon-adsorbent material for natural gas storage
Techniques for manufacturing carbon adsorbent materials with highly tuned pore properties have been developed by EnerG2 Technologies Inc. (Seattle, Wash.; www.energ2.com). The technology platform produces carbon adsorbents that enable the storage of natural gas at significantly lower pressures than those…
Engineered wetlands technology now available for wastewater treatment
Water treatment technology from Alcoa Inc. (Pittsburgh, Pa.; www.alcoa.com) that includes engineered areas of natural wetland vegetation is now available commercially for the first time. The engineered wetlands technology can lower capital and operating expenses, as well as energy consumption,…
A self-cleaning electrolytic cell that converts waste streams into disinfectants
Dealing with wastewater streams in petroleum refineries and petrochemical operations is often a trying task — environmentally, economically and logistically — especially as regulations on salinity in waste streams are tightened. However, many waste streams actually contain useful components, such…
Selectively recover CO with this soft nano-porous material
Professor Susumu Kitagawa’s group at Kyoto University (Kyoto, www.sbchem.kyoto-u.ac.jp/kitagawa-lab/index-e.html) has developed a new soft nanoporous material that selectively adsorbs carbon monoxide from gas mixtures. The researchers believe their achievement will enable the separation and recycling of CO from the emissions…
Making liquid fuels from waste plastics
Gasoline-like fuel suitable for internal combustion engines can be obtained from the pyrolysis of plastic waste, according to a study conducted by a team of people from Gadjah Mada University (Yogyakarta, Indonesia; www.ugm.ac.id), University Sains Malaysia (Penang, Malaysia; www.usm.my), and…
Continuous crude-oil production from algae
Scientists at Pacific Northwest National Laboratory (PNNL; Richland, Wash.; www.pnnl.gov) have developed a continuous process for generating crude oil from algae that they believe can lower the cost of producing algae-based fuel. The process works by combining hydrothermal liquefaction and…
