Membranes are widely used in a variety of industrial separation processes, but the polymeric materials that make up many membranes are not durable enough to handle extreme conditions, such as processes with low pH or hazardous-metal content. Membrion, Inc. (Seattle,…
RO Membranes Toray Industries, Inc. (Tokyo, Japan; www.toray.com) has developed a highly durable reverse osmosis (RO) membrane that is said to offer double the resistance to cleaning chemicals of conventional counterparts. This reduces performance degradation from membrane wear and simplifies…
By combining mechanical integrity and reliability programs into a single framework, plants can streamline their asset maintenance strategies and mitigate all types of risk Asset maintenance first hit the headlines during the late 1980s when it became a target for…
Steam-heated storage tanks are critical to manufacturing processes, and prioritizing reliability in tank-system design and operations can mitigate unwanted issues Storage tanks are essential to the chemical process industries (CPI), and they require significant capital investment to ensure optimal installation…
Hydrogen fuel cells and electrolyzers will be crucial technologies as the global energy transition progresses. However, both devices are often hampered by issues with durability and material costs — mainly associated with their membrane elements — which have slowed their…
Researchers at Goethe University Frankfurt (www.uni-frankfurt.de) and Kiel University (both Germany; www.uni-kiel.de) have developed a new sensor for the detection of bacteria. It is based on a chip with a surface coating that ensures only very specific microorganisms, such as…
The production and processing of cathode active materials (CAM) are among the largest contributors to the cost of lithium-ion battery manufacturing. Typical CAM manufacture involves multiple, multi-phase steps in a co-precipitation process that requires a large amount of water and…
Hydrogen chloride is an important byproduct of the chemical industry, with over 9-million ton/yr generated by industrial chlorination processes, such as the production of chloromethanes and polymers (polyurethanes and polycarbonates). Although HCl can be easily recovered by gas scrubbing with…
There have been several recent announcements regarding regulatory changes that affect the chemical process industries (CPI). One of the latest is a set of final rules announced on April 9 by the U.S. Environmental Protection Agency (EPA; www.epa.gov) that significantly…
A large selection of ion-exchange resins is available today for a constantly growing variety of applications. In order to choose the appropriate resin for a specific application, it is important to carefully evaluate the range of resin and process properties…
