The CP critical time for waxy w/o e

The CP critical time for waxy w/o emulsions is predicted by using thenewly developed models, as show in Table 7. As can be seen from thetable, the relative deviations between the statistical mean values and thepredicted values for both models are within 10.0%, and the maximumand the minimum deviation are 7.0% and 0.4% separately. The newlyestablished prediction models can predict the capability of wax crystalsto prolong the CP hydrate critical time in waxy w/o emulsions. Inaddition, the prediction models can also describe the “convergence effect” [56] of CP hydrate critical time with the increase of wax content inwaxy w/o emulsions. The average relative deviations between thecalculated and experimental critical time are 4.19% and 2.19% for thetwo models. Consequently, it is more reasonable to use Langmuiradsorption function for describing the effect of wax crystals on the masstransfer limitation of the oil–water interface.
