Kingston Process Metallurgy Inc. (KPM) is a process development company working in a broad range of metallurgical processes, including molten salt electrolysis. KPM currently sees an opportunity for electrolytic cell improvements. In order to improve KPM's abilities in cell improvements, and understand the fundamentals governing electrolytic cell operation, KPM is interested in performing physical and mathematical modelling studies in collaboration with the University of Toronto. A detailed computational fluid dynamics model of the electrolytic cell will be developed and will be coupled with transient heat transfer. The primary step is to model the electrolysis process with the evolution of gas between the anode and cathode. As the gas and metal bubbles rise, there is more of each within the anode/cathode space. This changes the velocity of the electrolyte, which must be taken into consideration for proper mass transport into the cell. For heat transport, there are a large number of heat sources and sinks that need to be accounted for, including the heat generated between the anode and cathode due to electrical resistance. The effect of bubble formation between anode & cathode and the change in spacing between anode-and cathode due to anode wear needs to be considered as well. KPM would work with the University of Toronto to supply information for a model on a single anode cathode pair (concentric), and cell containing molten salt. A better understanding of electrolytic cell design will directly improve KPM's consulting practice in light metals for its clients and improve its ability to secure larger contracts in this area. Direct benefits will also include the training of highly qualified personnel for employment within Canadian mining and metals companies, and improving competitiveness of a Canadian company both of which will boost Canadian excellence in science and technology.
