Vapor-Liquid Equilibrium Calculations Using K Values

Equation (3-9), which is known as the Rachford-Rice equation, has excellent convergent properties and can be solved by Newton’s method. Take the derivative of the function F with respect to V/F (or f), (3-10) The following procedure can be used to solve for V/F: - Check to see if T is between Tb and Td. - f = (T - Tb)/(Td - Tb) Iteration ... ................
