Vapour-liquid Equilibrium Data for C5 Saturated-Unsaturated Hydrocarbons Solutions with Solvents Monopropylene Glycol, Dipropylene Glycol or N-Methyl-2-Pyrrolidone

Abstract:

The influence of monopropylene glycol (MPG), dipropylene glycol (DPG), or N-methyl-2 pyrrolidone (NMP) solvents on the relative volatility of C5 alkanes in mixtures with C5 olefins was estimated based on vapour-liquid equilibrium data determined experimentally. An Othmer type equilibrium apparatus was used and compositions of phases were established by gas chromatography. The solvents capacity for saturated - unsaturated hydrocarbons separation by extractive distillation is quantified by the relative volatility am values, which were calculated from the experimental results. The two key parameters, Rmin, and Nmin (minimum reflux ratio and minimum number of theoretical trays), for the design of a distillation column aimed to separate C5 alkenes from a refinery C5 cut, were consequently computed for three scenarios of bottom product quality. Values of Rmin and Nmin thus estimated proved the capability of the three tested solvents for C5 olefins separation by extractive distillation, their separation capacity increasing in the order : MPG[DPG[NMP. Keywords: C5 fraction, vapour-liquid equilibrium, Othmer, extractive distillation
