METHOD FOR PREVENTING AND ELIMINATING SOLID DEPOSITS IN PIPELINES AND INSTALLATION IMPLEMENTING THIS METHOD Russian patent published in 2023 - IPC B08B9/02 

FIELD: pipelines.

SUBSTANCE: inventions are designed to prevent and eliminate solid salt deposits in pipelines. A method is described for preventing and eliminating solid deposits in pipelines, including salt and asphaltene-resin-paraffin deposits, which includes installing additional containers with liquid on the pipeline, in which shock acoustic waves are created that destroy deposits with their subsequent removal, while outside along the axis of the pipeline along its containers with liquid are set with the possibility of installing a single container, the minimum number n1 of which in relation to their maximum possible number n2 is chosen with the possibility of choosing n1=n2=1 from the ratio 1.01≤(n1+n2)/n2≤2, the minimum values V1 of the volumes of the containers in relation to the maximum values V2 of the volumes of the containers are selected with the possibility of choosing V1=V2 from their interconnected dependence 1.005≤(V1+V2)/V2≤2, and the minimum values of the lengths L1 of the containers, their heights H1 and widths S1 in relation to the maximum values of the lengths L2 of the containers, their heights H2 and widths S2 are chosen with the possibility of choosing L1=L2, H1=H2, S1=S2 from the dependence 1 that interconnects them 1.01≤(L1+H1+S1+L2+H2+S2)/(L2+H2+S2)≤2, dome-shaped discharge modules are placed in each of the containers with the possibility of placing a single module, the minimum values V3 of the volumes of which in relation to the maximum values V4 of their volumes are selected with the possibility of choosing V3=V4 from the relationship between them 1.001≤(V3+V4)/V4≤2, and the minimum number n3 of modules in relation to their maximum possible number n4 is chosen with the possibility of choosing n3=n4 from the ratio 1.025≤(n3+n4)/n4≤2, modules are placed along the axis of the pipeline, distributed in a plane perpendicular to the axis of the pipeline, evenly or unevenly over its cross section, electrodes with insulators are placed inside the discharge module with the possibility of placing a single electrode, the minimum number n5 of which in relation to their maximum possible number n6 is chosen with the possibility of choosing n5=n6 from the ratio 1.1≤(n5+n6)/n6≤2, simultaneously or sequentially, high-voltage pulses from a high-voltage pulse generator are applied to the electrodes, a discharge is produced between the electrode and the pipe surface, thereby creating a shock wave, focusing the shock wave on the pipe surface using the dome of the discharge module, destroying solid deposits inside the pipe with a shock wave, washing out disrupted deposits from the pipe by the fluid flow and/or create a slope of the pipe for them to slide and be removed from the pipe. The installation for the implementation of the above method is described.

EFFECT: cleaning of any type and thickness of solid salt deposits in pipelines of any length and diameter, with or without bends, any degree of blockage of the pipeline, with the possibility of preventing the formation of solid salt deposits in the pipeline, improving the quality and speed of cleaning the inner surface of the pipeline.
