Abstract
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 (104–108) 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.
