有机相变乳液中HCFC–141b水合物生成及稳定性
Formation and stability of HCFC–141b hydrate in organic phase change emulsion
摘要
Abstract
To promote the hydrate formation , surfactants Tween 80 and Span 80 are added as emulsifiers in HCFC-141b, organic phase change materials (n-decanoic acid and dodecyl alcohol) and water system. Organic phase change material-surfactant-refrigerant aqueous emulsion is prepared by high-speed stirring. Emulsion increases the contact area of water and HCFC–141b. The effects of organic phase change materials and surfactants on the formation of hydrates are investigated experimentally under static conditions. The results show that emulsifier can effectively increase the cold storage capacity of hydrate, reduce the induction time of hydrate formation, and reduce the randomness of hydrate formation. The lower the temperature of emulsion systems, the better hydrate promotion effect. The hydrate formation/decomposition cycle experiments show that the emulsion system with Tween 80 has good stability, and the organic phase change emulsion improves the stability during the hydrate formation/decomposition cycle.关键词
