Abstract
The optimum volume ratio of reactor and regenerator which minimizes the total volume of the two is obtained for solids circulation systems where shrinking core kinetics hold for both gas-solid reaction and regeneration. For the general case the optimum volume ratio for a fixed flow rate of solids is represented graphically in terms of reaction and regeneration conditions. For a special case an approximate analytical solution for the minimization is obtained. The procedure to determine the optimum required volume for the reactor and that for the regenerator is also dealt with.
The effect of reaction and regeneration conditions and of solids flow rate on the optimum volumes is discussed.
