Experimental study of gas content in a two-phase system of sunflower oil-nitrogen with changes in temperature and flow rates

The hydrodynamic characteristics for the technological operation of bubbling vegetable oil with an inert gas were studied in laboratory conditions on a specially made experimental stand. The experiments were carried out at a liquid layer height of 0.8 m in the temperature range of from 20 °C to 120 °C and a specific nitrogen consumption of from 0.073 l/(min·kg) to 1.93 l/(min·kg). A linear dependence of the change in gas content on the specific nitrogen consumption was established. The upper limit value of the specific flow rate of 1.3-1.4 l/(min·kg) was determined to achieve the best gas content of the studied two-phase medium at the temperatures of from 90 °C to 115 °C. The results can be used to create promising equipment in oil and fat production, and also to expand the understanding of the hydrodynamics of gas-liquid systems with viscous liquids.
