Attention to the design of bulk-solids pneumatic-conveying pipelines can help avoid conveying-system problems, such as low conveying rates, plugging, excessive wear-and-tear in the conveying line, high conveying-system pressure drop, product breakage, fines generation and product cross-contamination. This one-page reference provides…
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…
In some situations, it might be necessary to remove or replace a bolt during operation. This article shows how to determine the proper bolt load to prevent leaks Bolted flange joints (Figure 1) are part of pressure vessel and piping…
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…
The recently concluded 5th annual Connected Plant Conference (CPC; www.connectedplantconference.com), held in Austin, Tex., illustrated both the real promise of Industry 4.0 digital tools to improve operational efficiency and safety at chemical process industries (CPI) facilities, as well as the…
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…
Storage tanks containing hazardous materials require safety instrumented systems (SIS) to prevent overfills. Digital technology in the latest level-measurement devices used in SIS enables remote proof-testing, which provides significant advantages At industrial facilities with tanks containing hazardous, flammable or explosive…
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) —…
Mitsubishi Gas Chemical Company, Inc. (MGC; Tokyo) has announced the expansion of Meta-xylenediamine (MXDA) production in Europe. MGC is expanding its production capacity of MXDA to meet the market growth in the epoxy, polyamide and isocyanate sector. MGC will be…
