abstract

  • Recent work has extended perturbation gas chromatography theory to multicomponent systems and has demonstrated the procedure for determining multicomponent equilibrium isotherms from response peak retention times. For accurate use of the technique for equilibrium and rate measurement and for processes involving membrane and zeolite separations, an understanding of the response curves is helpful. This paper presents a tractable model for calculating multicomponent perturbation gas chromatography elution curves which incorporates both phase equilibrium and interphase mass-transfer rates. Example calculated curves agree well with experimental data and provide insight into peak shapes and their development. Eigenpulse injections can be used to simplify responses experimentally, enabling accurate retention times (for measuring equilibrium) and peak dispersion rates (for evaluating mass-transfer effects) to be obtained. 1988, American Chemical Society.
