Direct Observation of the Effect of Sodium Dodecyl Sulfate (SDS) on the HCFC-22 Hydrate Formation in a Static Mixer

摘要

Direct observation of the formation behavior of HCFC-22 hydrate in a Kenics type static mixer was conducted focusing on the effect of an addition of a surfactant, sodium dodecyl sulfate (SDS). The formation pattern of the hydrate was changed by the SDS addition from "slurry" to "plug," and a continuous cycle of hydrate film formation and bubble escape was observed. The hydrate formation rate was increased about 10-fold by the addition of SDS (1000 ppm).
