extractive distillation
3.A batch extractive distillation process with mixed solvents was studied experimentally in a middle-vessel batch distillation column.
5.A new process for separating propylene and propane in ethylene production using extractive distillation with aqueous ACN was put forward.
6.Product are refined by extractive distillation , CHCl3 as solvent, and their dosages are V (AEC) : V(CHCl3) = 1: (2.0-2.5).
7.Analysis by Gas-Liquid Chromatography of DEG as Solvent in Extractive Distillation of Mixed Alcohols of Low Carbon Contents
8.Taking water as the extractant, the purified cyclohexane with the purity of 99.91% can be obtained by the method of extractive distillation.
9.An extractive distillation process for recovering high purity benzene from pyrolysis gasoline was studied. The solvent selected was N -formylmorpholine(NFM) promoted by a co-solvent(COS).
10.The mixed extractant used in the extractive distillation of benzene-methyl cylcopentane was well selected by modified UNIFAC model. The process of batch extractive distillation of benzene-methyl cylcopentane using mixed solvent(N-formylmorpholine(NFM)-ethylene glycol(EG)) was theoretically and experimentally investigated,with the emphasis on the effect of the mixed ratio between NFM and EG and the solvent ratio.
