Studies of the Use of Ultrasonic Equipment for the Removal of Asphalt-Resin Paraffin Deposits at Oil and Gas Transport and Storage Facilities

Abstract

The article is devoted to the problem of cleaning oil transport and storage facilities from asphalt-resin-paraffin deposits. The issues of the use of ultrasound at oil transport and storage facilities for the removal of asphalt-tar and paraffin deposits are considered. The classification of methods for removing asphalt-tar and paraffin deposits in wells, pipelines and reservoirs is formulated. The review of scientific works on the use of ultrasound and ultrasonic installations for changing the basic physical and chemical characteristics of oil and tank cleaning is presented. Based on the analysis, a list of experimental studies is formulated that must be performed for the further formation of the scientific and technical base for the use of ultrasonic exposure for the removal of deposits. An overview of modern achievements in this field is presented, including scientific works on the use of ultrasound to accelerate the removal of deposits. An approach to the destruction of deposits directly during the operation of the tank due to the descent of the emitter to the surface of the boundary of the phases "oil-deposits" is considered. A system of mathematical equations has been developed that simulates the process of changing the temperature and melting of deposits, taking into account the operation of an ultrasonic emitter. As a result, the velocity of the movement of the melting front of deposits is determined depending on the duration of exposure. The recommended duration of exposure at each installation point is determined.
