Applications of the bipolar trickle tower reactor
Applications of the bipolar trickle tower reactor
In title investigation of the use of the bipolar trickle tower as an industrial plant, the atatnplas of typical practical systems studied were the generation of hypobromite, the spoxlgstion of propylene, and the recovery of copper, lead, cadmiun and silver from very dilute solutions. The first is a simple reaction which enables precise monitoring of product. The epoxidation of propylene requires additional chemical steps. The removal of heavy metals such a those listed is fundamental to the treatment of all effluent, to the economics of the photographic industry, and in meeting the challenge presented by increasingly severe legislature covering the ecological impact of toxic substances. This investigation began with an analysis of the potential profile within the reactor subject to variation in the nature and concentration of electrolyte, the reactor geometry, the total applied potential and occasionally the electrolyte flow rate, leading to the formulation of appropriate recommendations for operation.Careful attention has been paid to the relations between reactor geometry, polarity of, the applied potential and electrolyte and gas velocities, permitting very efficient production of propylene oxide (e.e. of 96-98%). An energy yield of 2.9 Kwh.Kg has been obtained. Copper deposition was studied as a function of applied voltage, electrolyte flowrate and the number of packed layers of Reschig rings in the reactor. A previous theoretical treatment for this type of reactor his been modified and applied to the cane of metal ion removal. It is shown that this model matches the experimental data well. The influence of reactor geometry on yield and efficiency has been studied for the generation of hypobromite and the observations explained.

Abstract
In title investigation of the use of the bipolar trickle tower as an industrial plant, the atatnplas of typical practical systems studied were the generation of hypobromite, the spoxlgstion of propylene, and the recovery of copper, lead, cadmiun and silver from very dilute solutions. The first is a simple reaction which enables precise monitoring of product. The epoxidation of propylene requires additional chemical steps. The removal of heavy metals such a those listed is fundamental to the treatment of all effluent, to the economics of the photographic industry, and in meeting the challenge presented by increasingly severe legislature covering the ecological impact of toxic substances. This investigation began with an analysis of the potential profile within the reactor subject to variation in the nature and concentration of electrolyte, the reactor geometry, the total applied potential and occasionally the electrolyte flow rate, leading to the formulation of appropriate recommendations for operation.Careful attention has been paid to the relations between reactor geometry, polarity of, the applied potential and electrolyte and gas velocities, permitting very efficient production of propylene oxide (e.e. of 96-98%). An energy yield of 2.9 Kwh.Kg has been obtained. Copper deposition was studied as a function of applied voltage, electrolyte flowrate and the number of packed layers of Reschig rings in the reactor. A previous theoretical treatment for this type of reactor his been modified and applied to the cane of metal ion removal. It is shown that this model matches the experimental data well. The influence of reactor geometry on yield and efficiency has been studied for the generation of hypobromite and the observations explained.
