Worcester 51/52 Series reduced-port flanged ball valves (photo) have been reengineered for global availability by standardizing the valves’ design, materials, construction and product certifications. The bubble-tight shutoff design and robust, live-loading packings in these valves minimize fugitive emissions, enhance safety…
P-XYLENE FROM CO2 Last month, a Japanese consortium announced the successful production and purification of p-xylene produced from CO2 at pilot scale. The University of Toyama (www.u-toyama.ac.jp), Chiyoda Corp. (www.chiyodacorp.com) and HighChem Co., Ltd. (www.highchem.co.jp) have been collaborating on producing…
For the first time, a hydrocarbon-based membrane has passed the performance and durability testing standards set by the U.S. Dept. of Energy (DOE; Washington, D.C.; www.energy.gov) for heavy-duty fuel-cell applications. Typically, membranes in fuel cells are made of perfluorinated materials…
Chemical recycling of waste polyolefins is difficult to achieve economically partly because of the stability of carbon-carbon bonds in the plastics. In a new approach, researchers at Pacific Northwest National Laboratory (PNNL; Richland, Wash.; www.pnnl.gov) and the Technical University of…
Today’s process sensors provide a real-time data foundation for asset management and process optimization across the enterprise For many decades, industrial process sensors have been used across the chemical process industries (CPI) to measure common process variables, such as pressure,…
The CDA-200 multi-shaft mixer (photo) features a two-wing anchor agitator and two medium-speed agitators, each fit with five rows of three-blade pitched turbines. The mixer can be supplied with two portable stainless-steel mixing vessels and transport covers for semi-continuous operation,…
Current electrolyzers for producing hydrogen use purified water as feedstock, but in the future, this could exacerbate freshwater shortages in some areas. Seawater is highly abundant, but the ions it contains undergo electrode side reactions, and cause corrosion in proton-exchange…
The Universidad Carlos III de Madrid (UC3M; Spain; www.uc3m.es) has patented a new system for capturing hyperspectral images — those capable of collecting information across a broad frequency range of the electromagnetic spectrum (near-infrared, mid-infrared and terahertz). The system can…
The demand for vanillin vastly outstrips the natural resources of this flavoring agent. A chemical process is thus used to produce the required large quantities of vanillin from petroleum, which is far less expensive than obtaining the substance from fermented…
Chemists at Hokkaido University (Sapporo, Hokkaido, Japan; www.global.hokudai.ac.jp) and the Institute for Chemical Reaction Design and Discovery have developed what is said to be the first high-performance catalyst specifically designed and optimized for solid-state, mechanochemical synthesis. The new approach was…
