Use this guide to aid the selection of conveying technologies for applications in powder and bulk solids handling Many sectors of the chemical process industries (CPI) — including chemicals, plastics, batteries, mining, power generation, plastics, food, agriculture, pharmaceuticals and others…
Biogas plants play an important role in defossilization — anaerobic bacteria in these plants break down biomass to form biogas which, on average, comprises up to 60% methane and more than 40% CO2. While the biogas is used to generate…
Presented here are practical points to help in the selection of plate-and-frame and air-cooled heat exchangers With a wider variety of heat exchangers to choose from than ever before, there are a number of variables to be considered when assessing…
Nickel alloys have long been the default choice for demanding applications in the chemical process industries (CPI). A new grade of stainless steel offers an alternative Demanding chemical engineering applications, such as plate heat exchangers (PHEs; Figure 1), tubing, pipes…
X-Materials (Orlando, Fla.; www.x-materials.com), the advanced materials division of Semplastics Inc., has developed a method for manufacturing a coal-containing ceramic polymer-composite material that is being used to make building materials, such as roofing tiles, as well as other products. According…
Platinum is widely used for many catalytic reactions, and because the precious metal is so expensive, efforts have been ongoing to reduce the amount of Pt required to perform reactions. Among these efforts are the use of nano-dispersions, clusters and…
Dispersion modeling of atmospheric releases from pressure-relief valves and other sources can be time-consuming. Follow this screening process to categorize which installations require detailed modeling and focus effort where it is most consequential The safe design of atmospheric relief/venting systems…
Henry Kister shares lessons learned from troubleshooting distillation towers On an assignment to troubleshoot a vacuum tower for a petroleum refinery, my team was tasked to “run simulations to determine why the heavy vacuum gas oil (HVGO) has a very…
A new membrane for separating emulsions is being fabricated using recycled carbon-fiber production scraps from aerospace manufacturing. “We think this is the first membrane of its type to be constructed from recycled carbon fibers,” explains Shuaifei Zhao, senior research fellow…
Countercurrent heat-exchange with difficult slurries, such as those of mineral ore or stringy vegetables, has not been possible because suspended solids pack and foul the shell of shell-and-tube designs and plug the passages in plate-and-frame units. Now, a recently patented…
