Plant Watch Arkema plans $90-million upgrade at Clear Lake acrylic acid plant January 11, 2017 — Arkema (Colombes, France; www.arkema.com) is investing $90 million at its Clear Lake, Tex. site to replace two acrylic-acid reactors, each with a capacity of…
A patented, inline absorption system has been developed and field-tested by ExxonMobil (Houston; www.exxonmobil.com), and has just been licensed to Sulzer Chemtech (Winterthur, Switzerland; www.sulzer.com). Because the tradenamed cMIST technology operates inside pipes, it replaces the need for conventional methods…
HVAC cooling tower A newly introduced cooling tower for building heating, ventilation and air conditioning (HVAC) has both its structural casing and fill made from high-density polyethylene (HDPE) resin that contains additives designed to prevent the growth of microorganisms and…
Tighter control, increased safety and versatility result from improved flow-measurement technology Flow monitoring and control are very important in the chemical process industries (CPI) because data gathered by flow-measurement equipment can pinpoint areas where a process can be improved and…
For a long time, it has been believed that the crystallization of zeolites is, by nature, a very slow process. The hydrothermal synthesis of zeolites is normally performed batchwise, requiring crystallization times on the order of days. Now, Toru Wakihara…
Two Australian companies — Australian Vanadium Ltd. (AVL; www.australianvanadium.com.au) and TNG Ltd. (both Perth; www.tngltd.com.au) — are now able to produce commercial-grade vanadium electrolyte for use in vanadium redox-flow batteries (VRFBs). Those batteries are increasingly gaining favor, primarily for grid-scale…
Researchers from the group of professor Ikuya Yamada at Osaka Prefecture University (Osaka, Japan; www.osakafu-u.ac.jp), in collaboration with the University of Tokyo, Japan Synchrotron Radiation Research Institute (Hyogo; www.spring8.or.jp) and Fuji Die Co. (Tokyo; www.fujidie.co.jp), have synthesized for the first…
The release of silver from industrial wastewater has caused serious environmental problems. Many methods have been developed to remove silver ions from industrial wastewater, including chemical precipitation, ion exchange, electrolysis, replacement, membrane and reverse osmosis. Several adsorbents have been used…
A new commercial manufacturing process for carbon nanotubes (CNTs) produces tubes in the range of 1–10 mm in length (5–12-nm dia.), two orders of magnitude longer than currently available CNTs, which typically have lengths from 5–20µm. “Despite attractive mechanical and…
Gas Innovations (La Porte, Tex.; www.gasinnovations.com) has signed a 15-year, pay-per-use agreement with Haldor Topsøe A/S (Topsøe; Lyngby, Denmark; www.topsoe.com) for a second on-site carbon-monoxide production unit, using Topsøe’s electrolytic Carbon Monoxide solution (eCOs) technology. The first eCOs unit in…
