Abstract

En fremgangsmåte for å forhindre kondensasjon av vann og derved forhindre hydratdannelse i gassfasen gjennom et undervannskompresjonssystem. Duggpunktet for vann i den utseparerte gassen beregnes med den tilsats av kjemikalier til brønnstrømmen oppstrøms scrubberen som er gjort på vanlig måte for å forhindre hydratdannelse i væskefasen og justere opp tilsatsen av kjemikalier til et innhold som tørker gassfasen til et lavt nok nivå til å unngå fare for hydrat, fortrinnsvis slik at duggpunktstemperaturen senkes til under temperaturen i sjøvannet som omgir kompressoranlegget med en viss sikkerhetsmargin.A method of preventing condensation of water and thereby preventing hydrate formation in the gas phase through an underwater compression system. The dew point of water in the separated gas is calculated by the addition of chemicals to the wellstream upstream of the scrubber as is customary to prevent hydrate formation in the liquid phase and to adjust the addition of chemicals to a content that dries the gas phase to a low enough level to avoid danger. for hydrate, preferably such that the dew point temperature is lowered below the seawater temperature surrounding the compressor system with a certain safety margin.
