As environmental and transportation regulations become more stringent around the world, treating spent acids is becoming less of an option and more of a necessity Acids play many different roles in a large number of sectors of the chemical process…
Designing a new solid-liquid filtration process or optimizing an existing one requires consideration of a number of factors aside from the type of filter that will be used. This one-page reference reviews two groups of considerations: one related to equipment,…
While some aspects of burner management systems may seem intuitive, overcoming misconceptions in their specification and design will help to elevate overall safety Boilers, burners, furnaces and fired heaters, along with any other fuel-burning equipment, are considered high-risk areas within…
Equilibrium data and related information gathered from a liquid-liquid extraction laboratory “shake test” can provide information for process feasibility and column-type selection in the scaleup of liquid-liquid extraction processes Most chemical engineers have had the experience of dealing with problematic…
This company’s vertical wet-pit cantilever pump (photo) features a fully recessed impeller that is designed for solids pumping in light to medium slurries in many applications, including floating retention-pond pumping systems. Flows up to 1,600 gal/min and heads up to…
This article provides a comparative study of two approaches to protect ASME semi-elliptical pressure tanks from overpressure in the event of a fire Calculating the wetted surface area is a crucial step to protect American Society of Mechanical Engineers’ (ASME)…
Better upfront planning and management can lead to safer, more productive processes throughout every phase of operation A standards-based approach to process safety — one that actively addresses risks across a plant’s lifespan — can lead to safer chemical processes,…
The patented Material Master bulk-bag discharging system (photo) includes bag-piercing knives for the discharge of materials from bulk bags with or without an outlet spout. The system utilizes a two-ton chain hoist to lift the bulk bag into the carbon-steel…
This article describes an approach that uses data analytics for finding and addressing root causes of process deviations that reduce energy efficiency in key plant utility systems, and shares three case examples Discussion about climate change has been taking place…
Typically, the presence of condensation substantially degrades the measurement signal strength of ultrasonic sensors, but new EchoTouch reflective ultrasonic liquid-level sensors (photo) work in areas with condensation. By orienting the transducer vertically, condensation runs off the unimpeded transducer face to…
