Detecting steam-trap leaks gets easier

Steam traps are designed to allow condensate, but not steam, to escape from a steam line. When they malfunction, however, numerous costly consequences can result including energy losses, insufficient heating to processes, maintenance issues and more. At its Global Users…

An in-pipe turbine system generates energy from water effluent

Hydrofoil turbines mounted inside gravity-fed water-effluent conduits can generate significant electrical power without impeding flow, a demonstration project has shown. The in-pipe turbine systems offer chemical process industries (CPI) companies a way to extract emission-free energy from flowing wastewater discharge…

November Chementator Briefs

  New block copolymer Nexar is the tradename of a block copolymer product recently commercialized by Kraton Performance Polymers (Houston; www.kraton.com) that has unique water-transport properties. Building on its earlier work in anionic polymerization of styrene-butadiene block copolymers, the company…

Predictive process control at a refinery wastewater treatment plant

To date, the difficult-to-treat contaminants and their related biological inhibition in petroleum refinery wastewater have defied efforts to bring predictive and mathematical process control to biological wastewater-treatment systems. Now, for the first time, engineers at Refinery Water Engineering & Associates…

A new catalyst for asymmetric-transfer-hydrogenation reactions

The Fine Chemicals div. of Takasago International Corp. (Tokyo, Japan; www.takasago.com) has commercialized Deneb: Oxo-Tethered Ruthenium (II) Complex, which shows higher catalytic activities compared to conventional RuCl (arene)(N-sulfonylated diamine) catalyst systems. The higher activity enables a reduction in catalyst loading…
