A strategic approach to asset and alarm management will reduce alarm fatigue, mitigate risk and support more effective response On April 20, 2010, an explosion on the Deepwater Horizon offshore drilling rig (owned by Transocean and operated by BP) killed…
Industrial electrolysis involves passing a direct electric current through an electrolyte to elicit a range of chemical reactions. Electrolyzers are key pieces of technology for producing many important industrial chemicals. This one-page reference reviews the basic general operation of an…
Optimizing electrical conductivity in next-generation batteries depends on carefully controlling process variables, such as mixing, particle-size distribution and temperature. Presented here is a discussion of how these process variables affect battery performance In the evolving landscape of energy storage technologies,…
Sliding vane pumps offer a potent processing option for low-viscosity liquids Multiple industries rely on process pumps for handling a variety of substances that help the world function as it does today. Those substances come in a wide variety of…
Any loss of containment for liquefied petroleum gas (LPG) can have potentially catastrophic results. This article details various LPG storage configurations with special focus on the design of mounded-bullet systems Liquefied petroleum gas (LPG) is a mixture of propane and…
The purchase price of an electric motor is generally thought to end up as a small fraction (2–3%) of the motor’s total lifetime cost, with the majority of costs resulting from the electricity used by the motor. This makes motor…
The inclusion of nozzle flexibility (directional spring rate) in pipe-stress analysis results in more realistic piping reactions on pressure-vessel nozzles, whereby it will be easier to meet the limited nozzle-load capacity of the nozzles. It will surely contribute to a…
Process heating systems are critical parts of chemical process industries (CPI) facilities. Unfortunately, the reliable, efficient operation of utility systems is often taken for granted, and they receive little engineering attention. This is perhaps understandable, since these systems play a…
The costs associated with installing and maintaining pressure-relief valves (PRVs) can often be reduced by equipping systems with upstream rupture discs Reclosing pressure-relief devices, commonly referred to as pressure relief valves (PRVs), are designed to allow for the release of…
Looking at the challenges and benefits of various recycling technologies, this article uses polymethyl methacrylate (PMMA) as an example to analyze the economics and design considerations for depolymerization processes Plastics are a valuable commodity in society and provide versatile materials…
