Abstract

Process for increasing the yield of aromatics and at the same time reducing the solvent content in the refining by obtaining pure aromatics in the extractive distillation, characterized in that a) the mixture. Consists of aromatics and non-aromatics is loaded approximately on the twentieth plate of a column of extractive distillation; (Machine-translation by Google Translate, not legally binding)
