Abstract

Det beskrives en fremgangsmåte for termo-kjemlsk avvoksing av hydrokarbonoverførlngslednlngersom etter bestemmelse av ledningens indre effektive volum omfatter å behandle den voks-holdlge ledningen med en vann-i-olje-emulsjon, l samme retning som produksjons- strømmen. Emulsjonen Inneholder uorganiske reaktanter som genererer nitrogen og varme, hvilken fluldlserer parafflnavsetnlngen som deretter avdrlves ved hjelp av rensesjlkt. Prosent fjernet paraffln fastslås ved å bestemme det endelige, indre effektive volumet.
