The solid density was calculated from the molar fraction of its components. Assuming the void fraction in the bed to be equal to 0.4, the densities of solid, pellets and bulk can be estimated. For the purpose of reactor sizing, the trickle-bed model was simplified to a plug-flow fixed bed model, as available in Aspen HYSYS®.

turbular reactor

Plug Flow Reactors Plug flow, or tubular, reactors consist of a hollow pipe or tube through which reactants flow. Pictured below is a plug flow reactor in the form of a tube wrapped around an acrylic mold which is encased in a tank. Water at a controlled temperature is circulated through the tank to maintain constant reactant temperature.

chemical mixing reactors

Chemical Mixing Methods . Jun 22, 2017 · For larger mixing applications, pilot scale mixers can be used. However, with a larger bulk, and a greater bulk flow, in the reaction vessel, many larger scale mixers produce a laminar type flow rather than a turbulent flow which sometimes leads to problems in scaling-up a process due to the two scales having different mixing dynamics.
