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…
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…
Understanding material characteristics is important in designing and defining process criteria for optimal performance of rotary and fluidized-bed dryers The ability to efficiently, reliably and consistently dry bulk solids in an industrial setting relies largely on tailoring the dryer’s design…
The new SumoFlo CELE-8103-D integral display transmitter (photo) features a 144 mm x 144 mm, four-line display that can simultaneously show flowrate, totalized flow, temperature and product density. Available in both panel-mounted and tabletop configurations, the new transmitter is designed…
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…
The pneumatically actuated P40 PD tank-bottom valve (photo) is designed for use in sterile applications. The sealing principle of the valve is based on the company’s PD sealing technology, which hermetically separates the actuator from the medium. All actuator parts…
For the first time, perfusion disc separators for continuous production and faster processing can be implemented in biopharmaceutical cell-harvesting processes based on labor-saving, easy-to-use single-use devices. The newly introduced perfusion separators in this series (photo) offer the same advantages as…
The Solidmix technology (photo) is suitable for the pre-drying of shredded battery scrap and has been optimized for the separation of the solvents contained in the batteries. By means of vacuum drying, the solvents can be quickly and reliably separated…
The Viper-28 flange-spreading wedge (photo) is said to be the most powerful flange spreader in the world, boasting a spreading force of 28 metric tons and a precision tip measuring just 5 mm. This tool handles a wide range of…
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…
