This paper presents results of a comparative analysis of several research methods for oil pipelines waxing process, which are based on the progress made with present-day laboratory equipment and the capabilities of software and hardware computational packages used to simulate properties of multiphase fluids and kinetics of complex multi-factor processes. This paper considers theoretical foundations of proven and substantiated mechanisms of the processes of wax formation and accumulation on the inner surface of oil pipeline walls, including main factors that impact the rate of such processes. The paper also points out disadvantages of the methods of static measurement based only on the diffusion factor of deposition of deposits, predominantly of the paraffin wax type; these static measurement methods preventing from taking into account the impact of other equally significant factors that accelerate and decelerate accumulation of deposits. This work highlights the most accurate methods to determine the chilling point or mass crystallization of paraffin waxes, which are recommended to be used in computerized simulation of the process.
