A new self-cleaning filter from Spiral Water Technologies Inc. (San Rafael, Calif.; www.spiralwater.com) can efficiently treat water with 25,000 mg/L total suspended solids (TSS). According to Spiral Water CEO Ashwin Gulati, the filters use much less energy — reportedly just…
Acoustic wave separation (AWS) technology can improve cell-culture clarification in biopharmaceutical applications by enabling high-efficiency, continuous removal of cells in a closed system without centrifugation. Developed by FloDesign Sonics (Wilbraham, Mass.; www.flodesign.org) and licensed to Pall Corp. (Port Washington, N.Y.;…
Understanding how different filtration methods work leads to a more informed decision when selecting a filtration system Filtration is arguably the most commonly used unit operation in the chemical process industries (CPI). The range of applications for this important unit…
A new composite-membrane distillation process capable of removing salt, toxic elements and microorganisms from water is being offered commercially for the first time this month. The process, known as NanoClear, was developed by Dais Analytic Corp. (Odessa, Fla.; www.daisanalytic.com) for…
A novel solvent can reduce the costs of capturing and recovering carbon dioxide from gas mixtures compared to the use of amine-based solvents, such as monoethanolamine (MEA). The solvent, along with an associated cyclic absorption-desorption process, was developed by Carbon…
Last month, Innsep AS (Trondheim; Norway; www.innsep.com) and EagleBurgmann Norway (Skedsmokorset;www.eagleburgmann.no) began a collaboration to develop Innsep’s Lynx Separator technology for protection of EagleBurgmann’s Dry Gas Seal systems for compressors. Lynx is a new technology for removing entrained liquids much…
A research team, led by Jongsoo Jurng and Gwi-Nam at the Korea Institute of Science and Technology (Seoul; www.kist.re.kr), has developed a nano-catalyst filter that can drastically reduce harmful substances in cigarette smoke. The team created the filter by evenly…
Japanese companies INPEX Corp. (Tokyo, www.inpex.co.jp), Chiyoda Corp. (Yokohama; www.chiyoda-corp.com), and Metawater Co., Ltd. (Tokyo, all Japan; www.metawater.co.jp) have been commissioned to build a small-scale demonstration facility that will use ceramic membrane filtration for treating produced water for Japan Oil,…
The seven commonly made mistakes discussed here often lead to poor filtration and separation performance and many associated problems For almost any chemical process industries (CPI) plant, contamination is a reality that can cause numerous associated — and often chronic…
New materials and designs help processors improve efficiency and reliability As in other areas of chemical manufacturing, processors want more efficiency from their distillation and mass-transfer operations. Increasing capacity, finding solutions to issues such as foaming and fouling that slow…
