Linear alpha olefins (LAOs) are hydrocarbons with the chemical formula CnH2n, characterized by linear chains and one double bond at the alpha position (Figure 1). Such hydrocarbons are important chemical intermediates, widely used in several industrial and consumer products according…
Taking a system approach to find the root cause of a problem can be more beneficial than simply replacing a problematic pump. This article explains why We want the best reliability with anything that we work with. In a plant…
Improved understanding of differential pressure (DP) flowmeter operation, along with best calibration practices, reduces maintenance errors Utilizing an orifice plate installed in a pipe and accurately measuring the differential pressure (DP) to calculate flow is one of most common methods…
Until now, manufacturing polymer-electrolyte membrane fuel cells (PEMFCs) that are small, light and capable of mechanical movement has been challenging using conventional methods. PEMFCs are composed of end plates, bipolar plates, gaskets, membrane-electrode assemblies (MEAs) and other assembly parts, of…
Conventional processes for manufacturing battery electrodes use toxic solvents and require a lot of space and energy. In contrast, DRYtraec — a new dry-coating process developed by the Fraunhofer Institute for Material and Beam Technology (IWS; Dresden, Germany; www.iws.fraunhofer.de) —…
In this episode of the Chemical Engineering podcast, senior editor Scott Jenkins speaks with Matt Dixon and Karim Mahraz, both engineers at Swagelok and experts on grab-sampling systems. Matt and Karim discuss the most common problems associated with grab sampling…
Here are recently published books with relevance to the chemical process industries (CPI). September 2021. Engineering of Power Plant and Industrial Cooling Water Systems. By Charles F. Bowman and Seth N. Bowman, CRC Press, 2021, 174 pages, $71.96. 2021 Guide…
Biological processes can be used for the conversion of greenhouse gases into added-value chemicals. With a new, unique high-pressure (up to 10 bars) fermenter, the Flemish Institute for Technology Research (VITO; Mol, Belgium; www.vito.be) is researching how these processes can…
Construction is underway on a demonstration plant for manufacturing 1,5-pentanediol (1,5-PDO) from bio-based furfural, a platform chemical that can be derived from plant-based hemicellulose sugars. The process under construction by the company Pyran Inc. (Madison, Wis.; www.pyranco.com) offers a lower-cost…
A new fibrous catalyst-support material can enhance a wide range of industrial catalytic reactions, allowing higher yields and reduced coke buildup compared to pellet supports. Unifrax (Tonawanda, N.Y.; www.unifrax.com) leveraged its expertise in ceramic materials to develop the high-alumina fiber…
