Design of Bulk-Solids Moving-Bed Heat Exchangers

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…

Facts At Your Fingertips: Hopper Outlet Geometry and Arching

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…

FOG separation technology expands to new application areas

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…

Facts at your Fingertips: Cyclone Separators

Removing solids from a stream of air or other gases is an important operation across virtually all sectors of the chemical process industries (CPI). In many cases, gas-solid separation is motivated by the need to reduce environmental impact and health…
