The liberation of gas hydrate R142b points during the experimental study of cold

Determined by future experiments. When cyberspace (S) sets the amount of alcohol in different fields 7 objects placed across the water table changes in the process of heat transfer coefficient curve 4 Conclusions 1) The decomposition of gas hydrate is a complex process of hydrate dissociation, gas phase and liquid water R142b while producing, R142b bubble rising diffusion of gas hydrate above the melting tank provides heat. In addition, the bubbles disturb the movement of the film, enhanced heat transfer. 2) The addition of propanol additive process of heat transfer coefficient of the cold put a clear impact: The addition of n-propanol led to put the initial stage of cold reduction of heat transfer coefficient; in the experimental range, the maximum heat transfer coefficient value is n-propanol additive content with the increase of; Generally speaking, the initial phase of the first cycle after cycle of heat transfer coefficient slightly higher than the heat transfer coefficient, after adding n-propanol, the cycle The initial phase of the heat transfer coefficient basically the same. 3) The addition of alcohol additives on Rl42b hydrate and cool the heat transfer coefficient history of the process has little effect. Were added to ethanol, ethylene glycol, propanol later. Put the initial stage of cooling process can not achieve the same maximum heat transfer coefficient of heat transfer coefficient, but experienced a rise and fall of the process. References 【1] E. D.
