摘要: Enhanced formation of HCFC141b hydrate was studied with HCFC141b emulsion before the hydrate formation. Tergitol TMN6 was selected as emulgator, HCFC141b and water were introduced into an airtight emulsifier at the molecular ratio of 17:1 and emulsified at the temperature of 14℃ under the stirring speed of 4000~6400 r/min. And HCFC141b hydrate formed and decomposed with the change of programmed temperature. The experimental results showed that with the new method HCFC141b hydrate began to form in the time of 30 min (in glycol-water bath) or 100 min (in air bath) even in static state, and under the same condition with conventional method (non-emulsion) the hydrate could not form, at least it difficultly formed. And in dynamic state HCFC141b emulsion formed hydrate in 20 min earlier than the mixed liquid did, liquid from hydrate decomposition was emulsified after brief stirring, and formed hydrate again more easily than the brand-new emulsion.
