where A is the specific interface area (1/μm), which represents thesurface area of dispersed phase in unit volume emulsion, ϕ is the watercut, d32 is the Sauter mean diameter of water droplet, μm. The parameters a and b can be obtained by fitting the critical time without waxcrystals and the specific interface area. The fitting results of parametersa and b are 0.0026 and 1.2283 respectively, and the detail of fitting results can be found in the Supporting Information A.The extension effect of wax content on CP hydrate critical time issupposed to be affected by the mass transfer limitation as shown in Fig. 4and Eq. (4), and the heat transfer limitation and heterogeneous nucleation due to the presence of wax crystals are ignored in this work. where Nm is the effect of mass transfer in the waxy w/o emulsions, Nm,Ris the reference effect of mass transfer in the system without waxcrystals
