PREVENTION METHOD OF HYDRATES FORMATION AND ELIMINATION IN HYDROCARBONS Russian patent published in 2017 - IPC E21B37/06 

Abstract RU 2635308 C2

FIELD: oil and gas industry.

SUBSTANCE: method involves the anti-hydrate reagent adding into hydrocarbons. In addition, one or more gases are supplied, in each of which the hydrates are formed at the pressure higher and the temperature lower than in hydrocarbons, and the mixture in which the hydrates formation does not occur at the initial pressure and temperature of the hydrocarbons is obtained. At the hydrates elimination, in addition to gases, the anti-hydrate reagent is also supplied, besides, the gases and reagent is supplied with the rates, that provides the necessary rate of hydrates decomposition, determined by the formula.

EFFECT: energy costs are reduced.
