Temperaturregulerende anordning, fremgangsmåte, samt undersjøisk ventiltre

En temperaturregulerende anordning (10) for å forebygge dannelse av alkanhydrater i en undersjøisk olje- og gassproduksjonsutstyrskomponent(12) har i det minste en strømningsbane (14) som et brønnfiuid tillates å strømme igjennom. Brønnfiuidet har en strømningstemperatur og en lavere, hydratdannende...

Zusammenfassung:	En temperaturregulerende anordning (10) for å forebygge dannelse av alkanhydrater i en undersjøisk olje- og gassproduksjonsutstyrskomponent(12) har i det minste en strømningsbane (14) som et brønnfiuid tillates å strømme igjennom. Brønnfiuidet har en strømningstemperatur og en lavere, hydratdannende temperatur hvor hydrater vil dannes i fluidet. Den temperaturregulerende anordning (10) omfatter et hus (18) plassert i varmevekslende forhold med hensyn til strømningsbanen, mens et fase- endrende material (16) er anordnet i huset. Det fase-endrende material har et smeltepunkt som ligger under strømningstemperaturen, men over den hydratdannende temperatur, slik at når temperaturen i det fase-endrende material faller til dets smeltepunkt, vil det fase-endrende material størkne og dets latente varme bli overført til brønnfiuidet for å holde temperaturen i brønnfiuidet i strømningsbanen over dets hydratdannende temperatur. The present invention embodies a temperature control device for preventing the formation of alkane hydrates in a subsea oil and gas production equipment component having at least one flow path through which a well fluid is permitted to flow, the well fluid having a flow temperature and a lower hydrate formation temperature at which hydrates will form in the well fluid, the temperature control device comprising a housing positioned in heat exchange relation with respect to the flow path and a phase change material disposed in the housing, the phase change material having a melting point which is below the flow temperature but above the hydrate formation temperature, whereby when the temperature of the phase change material drops to its melting point, the phase change material will solidify and its latent heat will be transferred to the well fluid to maintain the temperature of the well fluid in the flow path above its hydrate formation temperature.
