By carefully considering equipment and plant design in processes involving powdered materials, fugitive dust issues can be reduced significantly Powdered ingredients that unintentionally leak from equipment in a manufacturing plant are known as fugitive dust. The risks associated with fugitive…
Presented here are equations governing heat transfer in a moving-bed heat exchanger, along with a numerical method for solving them Moving-bed heat exchangers (MBHE) represent an efficient method for heating or cooling bulk-solid materials compared to other technologies, such as…
When transferring stored bulk-solids materials from hoppers, bins and silos, flow stoppage can occur because of bridging or arching at the vessel outlet. Hopper outlets must be large enough to prevent cohesive arches or stable ratholes from developing. Determining the…
The Process Equipment Manufacturers’ Association (PEMA; Falls Church, Va.; www.pemanet.org) and the Bulk Solids Innovation Center (BSIC; bulk-solids.k-state.edu) at Kansas State University today announced the establishment of a partnership. “PEMA members will have access to unique educational, consulting and testing…
A holistic approach to bulk-solids-feeding installations can improve the effectiveness and efficiency of operations involving solids handling Many chemical processes involve the extraction of bulk solid materials at a controlled rate from a storage vessel for delivery into the process.…
The following is a list of recently published books with relevance to the chemical process industries (CPI): Trevor Kletz Compendium: How his Best Process Stories are Still Relevant Today. Andy Brazier, Fiona MacLeod, David Edwards and others, Elsevier Press, 2020,…
Fats, oil and grease (FOG) waste can create environmental problems for water-treatment and sewage systems, but can be a potential resource if collected and separated efficiently. A technology originally developed by Downey Ridge Environmental Co. (Lansing, W.Va.; www.greasezilla.com) to separate…
