A new pilot project brings together advanced membrane filtration with non-thermal, zero-liquid-discharge (ZLD) solvent exchange to efficiently treat high-salinity produced water from oil-and-gas operations. PetroH2O Recovery (Southlake, Tex.; www.petroh2o.com) is currently building a pilot plant with the capacity to process…
Splitting water with sunlight is a sustainable and environmentally friendly way to make hydrogen, but the conversion efficiency is presently very low, because current photocatalysts only work using ultraviolet radiation — a small fraction (3–5%) of sunlight. Now, a promising…
Bio-isoprene Yokohama Rubber Co. (Tokyo, Japan; www.yokohama.com) has developed what is said to be the world’s first technology capable of efficiently producing isoprene from biomass. The new breakthrough is the result of joint research with Riken (www.riken.jp) and Zeon Corp.…
Plant-based extracts, such as antioxidants, phytochemicals and polyphenols, are used in a number of end-markets, including cosmetics, foods and nutritional supplements. A proprietary, low-polarity, pressurized-water extraction method is set to drastically improve the recovery of useful ingredients from botanical sources.…
Almost all phosphoric acid is produced via the wet-acid process (WAP), which requires relatively pure raw materials and produces large volumes of a potentially hazardous, special waste called phosphogypsum, which is highly regulated in terms of storage and disposal. A…
In a first-of-its-kind endeavor, a hydrogen-fluoride-based alkylation unit producing linear alkyl benzene (LAB) is being converted into a solid-bed alkylation unit that employs UOP’s (Des Plaines, Ill.; www.uop.com) Detal-Plus alkylation technology for LAB. LAB is used in the production of…
Concern with energy efficiency has increased the popularity of window glass coatings that control the amount of sunlight that passes through, as well as windows made of thin solar cells that can turn them into electricity generators. Now researchers from…
TPA from PET bottles A chemical method previously developed for recovering monomers from polyester blend fabrics and textiles has now been adapted for use with waste plastic bottles made from polyethylene terephthalate (PET). The BCD Group (Cincinnati, Ohio; www.bcdinternational.com) developed…
Sunvapor Inc. (Livermore, Calif.; www.sunvapor.net) was awarded a grant from the U.S. Dept. of Energy (DOE; Washington, D.C.; www.energy.gov) last month to scale up its Green Parabolic Trough Collector, a solar thermal technology that cuts construction costs by half compared…
Flexible micro light-emitting diodes (LEDs) — a sub-100-µm light source for red, green and blue light — have become a strong candidate for the next-generation display due to their low power consumption, fast response, and flexibility. The previous micro-LED technology…
