Abstract
The paper presents the results of calculations of the P-T diagram of “ice phase (liquid phase)–gas phase–hydrate phase” equilibrium for freons R23 and R34a and 90%R23+10%R134a mixture. It is shown the freon R134a forms a stable CS-II hydrate phase in the temperature range of 260–280 K and pressure range of 0.0267–0.21 MPa and freon R23 creates a stable CS-I hydrate phase in the temperature range of 260–280 K and pressure range of 0.238–0.75 MPa. The calculation results are consistent with the known experimental data. It is shown that addition of 10% of R134a to the freon mixture results in the formation of CS-II hydrate phase in the temperature range of 260–280 K and pressure range of 0.0167–0.15 MPa.
