Experimental Study on the Solubility of O₂ and N₂ in the Liquid Oil at Low Pressure

Abstract:

The solubility of oxygen (O2) and nitrogen (N2) in the liquid oil (non-volatile oil: soybean oil and sunflower oil, volatile oil: aviation kerosene) were measured in the temperature with 293.15 K, 303.15 K and 313.15 K, and pressures up to 0.1MPa. The experimental data in soybean oil and sunflower oil were processed by R-K gas state equation, and based on this to analysis the data in volatile oil: aviation kerosene. The results show that solubility of O2 and N2 in liquids is in linear relationship with pressure, but nonlinear relationship with temperature, while, under the condition of same temperature and pressure, solubility of O2 is far greater than N2 both in non-volatile oil and volatile oil. The relationship between the solubility of oxygen (nitrogen) and pressure (temperature) can be useful in practical applications. Specifically speaking, it provides valuable references to help developing the storage technology of edible oil and extending the shelf life of food, etc.
