Abstract
Fluidized bed reactor studies were performed on the Claus reaction, i.e. 2H sub(2)S + SO sub(2) if and only if 3/n S sub(n) + 2H sub(2)O. The basic objective was to determine whether the performance of the Claus process could be improved by replacing conventional fixed bed reactors with fluidized bed reactors. A computational procedure was developed which, unlike previous methods, does not require the user to specify the initial values for the iterative solution of the equilibrium equations. It is therefore possible to achieve, consistently, significant reductions in computer time and cost. The computer programme was used to simulate various idealized Claus plants. The results of the equilibrium calculations indicated that, for feed gases consisting of pure H sub(2)S, sulphur conversions in excess of 99% are attainable by using a Claus furnace and two fluidized bed reactors in series.
