Explosive boiling-up of superheated gas-saturated alkanes

The spontaneous boiling-up kinetics of liquid alkanes (methane, ethane, and propane) saturated with one of the following gases: helium, hydrogen, nitrogen, or methane is studied. The solution nucleation rate temperature, baric, and concentration dependences in the interval $(10^4$–$10^8)$ m$^{-3}$ s$^{-1}$ are determined using the mean lifetime method. The measurements were carried out at pressures of $1$–$2$ MPa and volatile component concentrations up to $6$ mol $\%$. The experimental results are compared with the classical nucleation theory in a macroscopic approximation. In contrast to pure liquid and liquid saturated with helium or hydrogen, the attainable superheating temperatures of solutions containing nitrogen or methane as a dissolved substance exceed their theoretically predicted values. The factors causing this mismatch are discussed.
