Residence Time Distribution of Solid and Liquid Phase in a Stirred Tank Reactor

Abstract

The residence time distribution (RTD) of solid and liquid phases in a stirred tank reactor has been studied in this article. Comparison with RTD of solid and liquid phases was also made. In a continuous stirred tank reactor (CSTR), factors influencing RTD are stirring speed, solid particle concentration, geometrical parameters of reactor as well as the location of the inlet and outlet of the fluid. Sea sand and water are used as solid particle and liquid phase. Limestone with the same particle size of sand was used as tracer of solid particle and 10% KCl solution was used as tracer of liquid phase. Two regions model was used to describe the flow pattern of the fluid in the tank, there is only one parameter on the model has to be evaluated based on the experimental data.
