EXCRETION OF BENZENE FROM REFORMING BENZENE FRACTION BY EXTRACTIVE RECTIFICATION USING MIXED SELECTIVE SOLVENTS
The article contains the results of benzene removal from the reforming catalysate benzene fraction by the extractive rectification using mixed solvent sulfolane — 3-methylsulfolane and its mixtures with N-methylpyrrolidone. Addition of N-methylpyrrolidone increases the process efficiency as well as allows the benzene extraction percentage rising at a lower ratio of the mixed solvent to feed.
