METHOD TO PRODUCE HYDRATE SUSPENSION THAT DOES NOT CREATE PLUG Russian patent published in 2011 - IPC C10G75/04 B01F5/06 E21B21/12 

FIELD: power engineering.

SUBSTANCE: pipeline is described, which comprises a static mixer and has a hydrocarbon flow flowing through it, besides, the specified hydrocarbon flow contains paraffin with a temperature that is higher than the temperature, when the specified paraffin is deposited on internal walls of the specified pipeline, besides, the specified flow contacts with the specified static mixer, or at the temperature, which prevents deposition of paraffin on walls of the specified pipeline, or at the time when the temperature of the specified hydrocarbon flow drops below the temperature of paraffin formation, and forms a pumped fluid medium of hardened paraffin particles in the hydrocarbon flow. A method is described to prevent deposition of paraffin from the hydrocarbon flow at pipeline walls, when the specified flow is passed through the static mixer to form a pumped fluid medium of hardened paraffin particles in the hydrocarbon flow. Also a method is described to prevent deposition of hard paraffin and to produce pumped fluid medium from a flow of fluid hydrocarbon with paraffin components, as well as a method to produce a pumped fluid medium from a flow of liquid hydrocarbons with paraffin components, hydrate-forming gases and water or salt phase, a method to produce a pumped fluid medium from a flow of hydrocarbons, which contains a water phase and paraffin components, a method to transport a well flow of hydrocarbons, containing water, via a manifold pipeline, when suspensions of dry hydrates are created, at least with one static mixer, and the specified suspension of dry hydrates is supplied into the specified manifold pipeline, a method to produce hydrocarbons and a method to produce dry hydrates, when at least a part of a hydrocarbon flow, containing water, is passed via a reactor of cold flow, thus reducing size of drops in the specified water of the specified hydrocarbon flow, and at least a part of the specified water is turned into dry hydrates, besides, the specified reactor of cold flow contains at least one static mixer.

EFFECT: exclusion of energised equipment use for melting, grinding or scraping of hard hydrates from inner surfaces of oil lines or pipelines.
