Baidakov, A. Pankov] Methods of measuring lifetime and continuous pressure decrease were used to study kinetics of spontaneous boiling-up of superheated ethane-methane solutions. The attainable superheats of solutions at two pressure values (1.0 and 1.6 MPa) and two concentrations of methane (2.1 and 6.0 mole %) were determined experimentally in the range of nucleation rate J = 1·104-3·108 s−1m−3. At temperatures 266.5, 270.0, and 273.15 K, the attainable stretching of the studied solutions was measured. The experimental results were compared with the theory of homogeneous nucleation. At nucleation rates J ≥ 2.5·106 s−1m−3, there is a fair agreement of the theory and experiment. The discrepancy in attainable superheat temperatures T n does not exceed 0.8 K. It is shown that significant underheating of solution to theoretical values T n at J < 2.5·106 s−1m−3 cannot be bound only with heterogeneous nucleation but is conditioned by other factors as well.
