According to commercial operation modeling the process of allocation 1,3-butadienes from raw fraction C 4 hydrocarbons by a method of extractive distillation with application DMF is carried out. By means modeling software of the computer model of process is developed, its adequacy and applicability in search of operating parameters is shown by an analytical way. The method of phase balance research by mathematical modeling. The model of reflux ratio calculation in the extractive rectification is presented.
