Present article is about distillation pilot unit for experiments with mixtures of organic liquids in continuous and batch mode. Some features and recommendations on design and exploitation of pilot units are given. The results of experiments of ethanol-water mixture separation in batch mode are presented. Concentration profiles of components along the column average and local values of HETP are determined.
