This Paper introduces a mathematical model and an algorithm is based upon the block tridiagonal matrix technique. Use of adiabatic flash combined with comparison of free energy values can automatically identify if there are two liquid phases in a stage. The initial guess value of the phase composition can be obtained in the computation of the adiabatic flash, with the principle that the component with maximum pseudo-infinit dilution activity is the major one having the largest possobility to emerge in another...

This Paper introduces a mathematical model and an algorithm is based upon the block tridiagonal matrix technique. Use of adiabatic flash combined with comparison of free energy values can automatically identify if there are two liquid phases in a stage. The initial guess value of the phase composition can be obtained in the computation of the adiabatic flash, with the principle that the component with maximum pseudo-infinit dilution activity is the major one having the largest possobility to emerge in another liquid phase. The ternary system of propanol-butanol-water is employed as an illustration problem to justify this method, and the satisfactory results were obtained.

This paper is a proposal for revamping the separation column in the catalytic cracking process. Pased on the study of multicomponent multistage adiabatic flash process, a new technology combining multistage flash with distillation is proposed. The results of simulation based on plant data reveal that the vapor and liquid flow rates in the tower are reduced greatly, the recovery ratio of the light component in the top is increased, the quality of the sidestreams and the bottoms is improved and the pressure in the heater is decreased in the new technology as compared with the old. The energy comsumption is cut down as compared with the technology of connecting two columns in series, i. e. the primary distillation column and main distillation column. The new technology has the features of using simple equipment and saving investment.
