Abstract. One of the stages of vegetable oil production — distillation, which is the most energy-intensive process, is considered. The system of operational sensor-based control of concentration of miscella, together with other parameters allows for principle of feedback more effectively regulate the process flow of miscella and heat transfer in all forms of distillation. A new method for determining the concentration of n-hexane in sunflower oil and high-oleic sunflower oil is proposed. The method is based on the study of the electrophysical properties of sunflower oil.
