METHOD FOR REDUCING VISCOSITY OF OIL AND PETROLEUM PRODUCTS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2023 - IPC F17D1/16 

FIELD: oil pipelines.

SUBSTANCE: heating of high-viscosity oil (petroleum products) at the facilities of the oil and gas complex used in the design and operation of field and main pipelines, at oil depots, as well as during the transshipment. The invention relates to pipeline transport of high-viscosity oil/petroleum products. Method for reducing the viscosity of oil and petroleum products includes sequential impact on the flow of oil/petroleum products in the pipeline. Induction heating by a high-frequency electromagnetic field is performed by an emitter mounted on a pipeline and connected to a field generator. Then, for the destruction of paraffins, ultrasonic treatment is performed with an emitter mounted in a pipeline connected to an ultrasonic generator. After that, to combine suspended particles of paraffins and asphaltenes into short chains, they are exposed to electromagnetic radiation of the radio frequency range by an emitter mounted in a pipeline and connected to an electromagnetic radiation generator. The device for implementing the method contains an induction treatment module, an ultrasonic treatment module and an electromagnetic treatment module. The inductive treatment module contains a high-frequency electromagnetic field generator and a spiral emitter mounted on a pipeline. The electromagnetic treatment module contains a high-frequency electromagnetic field generator and an electromagnetic emitter made in the form of a plate mounted in the internal cavity of the pipeline. The ultrasonic treatment module contains an ultrasonic generator and an emitter mounted in a pipeline. Liquid temperature sensors are mounted in front of the spiral emitter and electromagnetic emitter in the direction of oil/petroleum products movement. A fluid flow sensor is mounted in front of the emitter of the ultrasonic treatment module, and a viscosity sensor and a valve are mounted behind the electromagnetic emitter of the electromagnetic treatment module.

EFFECT: minimization of power consumption to reduce the viscosity of oil/petroleum products.
