Abstract

Det tilveiebringes en fremgangsmåte for å beskytte en hydrokarbonledning i en periode med redusert hydrokarbonstrøm. Denne fremgangsmåte omfatter innføring av nitrogen i ledningen under en periode ved et trykk på 1 til 350 bar g og i en mengde av (1,5 til 35).A kg/sek (der A er det indre tverrsnittsareal av ledningen i kvadratmeter) i et tidsrom t timer der t = p.d/n der d er lengden i km for ledningen fra nitrogeninnføringslokasjonen og n er 10 til 400.
