Development of Measurement Methods for Monitoring the Effects of Shed Fouling in a Fluid Coker Stripper
… sheds in fluid and flexi-cokers restricts solids recirculation, leading to flooding and a unit shutdown. This thesis develops non-intrusive methods to detect fouling growth and provide advanced warning before critical operating limits are reached. Experiments were performed in a …

Improvement of the digestion of cattle slurry via the process of co-digestion
… the volumetric methane yield by introducing solids recirculation to the co-digestion process with the objective of maintaining the slowly degradable fraction of the maize and cattle slurry in the digester for longer periods. This proved not to be a viable option with the methane production …

Numerical modeling of cold flow and hot gas desulfurization in a circulating fluidized bed
… A model with linear algebraic approximation to solids viscosity of the form, mus = 5.34epsilons, (epsilon s is the solids volume fraction) with an appropriate boundary condition at the wall obtained by approximate momentum balance solution at the wall to account for the solids recirculation is …

Examination of Silica Removal with Solids Recycle for Reverse Osmosis Pretreatment
… a system operating around a pH of 9.5 or 10 with solids recirculation. Mg(OH)2 and Fe(OH)2 were tested in Phase 2. The concentrations of dissolved MgCl2 and freshly precipitated (also referred to as preformed) Mg(OH)2 used in Phase 1 were 100, 200, 600, 1,000, 1,200, and 10,000 mg/L as Mg2+. The …
