Abstract

Foreliggende oppfinnelse vedrører en fremgangsmåte for å hindre oppbygning av avsetninger på den indre veggen av en struktur som fører en første hydkarbonfluidstrøm ved en første temperatur inneholdende avsettende materiale, den første temperaturen er over en temperatur for avsetningstilsynekomst (Deposit Appearance Temperature) av det utfellende materialet, der den første strømmen blandes med en kjøligere andre kimstrøm med en andre temperatur omfattende kimpartikler for å felle ut det utfellende materialet, og den resulterende blandingsstrømmen føres ytterligere nedstrøms, der den første strømmen avkjøles på en kontrollert måte til en tredje temperatur nærmere den andre temperaturen av den andre strømmen før blanding. Oppfinenslen vedrører også et system for fremgangsmåten.The present invention relates to a method for preventing the build-up of deposits on the inner wall of a structure which conducts a first hydrocarbon fluid flow at a first temperature containing depositing material, the first temperature being above a Deposit Appearance Temperature of the precipitating material, wherein the first stream is mixed with a cooler second seed stream with a second temperature comprising seed particles to precipitate the precipitating material, and the resulting mixing stream is conducted further downstream, where the first stream is cooled in a controlled manner to a third temperature closer to the second temperature. the second stream before mixing. The invention also relates to a system for the method.
