Mass exchange during rectification of multicomponent mixtures of aromatic C/sub 9/ hydrocarbons

Journal Article:

Abstract

The effectiveness is determined of separating a multicomponent aromatic hydrocarbon (ArU) mixture into binary ones relative to the composition of the initial mixture. The study is conducted in mixtures of ArU which contain: C/sub 8/ ArU, isopropylbenzene, n-propylbenzene, ethyloluene, 1,3,5-trimetylbenzene, 1,2,4-trimethylbenzene, 1,2,3-trimethylbenzene and C/sub 10/ ArU. The total content of the C/sub 8/ and C/sub 10/ ArU is less than 2%. The constants of the phase equilibrium of the components are obtained through experiments or are calculated through the Chao-Sider method. The separation of the multicomponent mixture was conducted in periodic, automated rectification column 30 mm in diameter, filled with a steel spiral with a free volume of 0.818 m/sup 3//m/sup 3/ and a specific surface of 0.785 m/sup 2//m/sup 3/ and an effective headpiece height of 1.5 m. The temperature of the housing was maintained with a precision of 0.5/sup 0/, the speed of vapors was maintained constant (0.231 m/sec) through regulating the pressure differential between the top and bottom with a precision of 0.5 mm of mercury. After reaching a stationary mode, samples of the distillate and the sediment were taken and were analyzed chromatographically with a precision of 0.25%.
