The focus is on paraffin deposits on the walls of the tubing. Devices will be analyzed to prevent them. The conditions of hydrocarbon deposits in Eastern Siberia are considered. Hydrocarbon fluid is in critical condition. Small changes in physical parameters lead to the launch of phase transitions. Such changes take place in the process of lifting the liquid to the surface. There is a drop in pressure and temperature. Natural gas is released and, as a result, conditions are formed for the precipitation of paraffin crystals. The adsorption capabilities of the tubing wall contribute to the initiation of paraffin deposits. Among the units designed to prevent this problem stand out hydrodynamic devices. Due to the creation of cavitation zones, local formation of crystallization centers is provoked. Moreover, these lacunae are in the stream, i.e., separated by a moving fluid from the pipe wall. These circumstances contribute to the removal of the resulting paraffin crystals up to the surface. At times, labor costs for cleaning the pipe walls from paraffin deposits are reduced. An important advantage of hydrodynamic devices such as swirlers, cavitators is the absence of moving parts. This ensures reliable operation and ease of modernization. Of interest is the property of device casings to keep clean from paraffin deposits. This circumstance is associated with concomitant vibration. Permanent shaking off of the rudiments of deposits occurs.
