Title
(EN) METHOD OF GENERATING A NON-PLUGGING HYDRATE SLURRY
(FR) PROCÉDÉ DE PRODUCTION D'UNE BOUE HYDRATÉE NON OBSTRUANTE
Abstract
(EN)
Method for reducing loss of flow due to hydrate solids deposits and wax deposition in a pipeline without the aid of chemicals and system for transporting a flow of wellstream hydrocarbons containing water, using a main pipeline and a cold-flow reactor connected to the main pipeline or within or forming a part of the pipeline, wherein at least a portion of the wellstream is fed to the cold-flow reactor. Also provided is a method for preventing hydrate nucleation and growth in a pipeline and preventing hydrate agglomeration as well as for preventing wax deposition. The provided method eliminates the use of energized equipment for melting, grinding or scraping hydrate solids from inside of pipelines or flowlines. Generating dry hydrates to be mixed with main flow of a wellstream is also described.

L'invention concerne un procédé permettant de réduire la perte de débit due aux dépôts de solides hydratés et au dépôt de cire dans un oléoduc sans l'aide de produits chimiques et un système permettant de transporter un écoulement d'hydrocarbures de courant de puits contenant de l'eau, à l'aide d'un oléoduc principal et d'un réacteur à flux froid connecté à l'oléoduc principal ou à l'intérieur ou faisant partie de l'oléoduc, au moins une partie du courant de puits étant injectée dans le réacteur à flux froid. L'invention concerne également un procédé destiné à empêcher la nucléation des hydrates et leur croissance dans un oléoduc et à empêcher l'agglomération des hydrates, ainsi qu'à empêcher les dépôts de cire. Le procédé ci-décrit supprime l'utilisation d'équipements électriques pour faire fondre, broyer ou rejeter les solides hydratés depuis l'intérieur des oléoducs ou des circuits d'écoulement. L'invention concerne également la production d'hydrates secs à mélanger à l'écoulement principal d'un courant de puits.
