ABSTRACT:
The computer time needed to simulate a multistage fractionating tower is decreased by programming the computer to solve the applicable equations in which there have been replaced the two principal variables, flow ratio and temperature, by a single principal variable S which is the product of the flow ratio times the equilibrium constant of a base component at each particular stage temperature. By so reducing the dimensionalities of the problem, there is achieved the reduction in computer time by successive iterative solution of the equations to achieve realistically close simulation of selected operations of the tower.
