Problems associated with the crystallization of paraffin from the oil in conveying pipes and pipes of heat-exchange apparatus and with the deposition of paraffin particles on the inner surface of these pipes are considered. Diffusion models of the kinetics of crystallization of paraffin and its deposition under the indicated conditions are proposed. A comparison of the results of calculations by these models with corresponding experimental data has given positive results.
