Abstract:
A method and system for dehydration of a gas phase and hydrate inhibition of a liquid hydrocarbon phase in a multiphase hydrocarbon fluid stream containing water. The method may include (i) separating the hydrocarbon fluid stream into a liquid phase and a first gas phase, (ii) adding hydrate inhibitor to the first gas phase, and (iii) separating off condensed liquids and a second gas phase. The first gas phase has a water dew point that is lower than the initial multiphase hydrocarbon fluid stream and the second gas phase has a lower water dew point than the first gas phase. The hydrate inhibitor has a water content that is low enough to enable it to dry the first gas phase, the hydrate inhibitor being separated off with the condensed liquids and mixed with a part or all of the liquid phase from the separation to inhibit the liquid phase.

Claim (Index 58):
A system for dehydration of a gas phase, wherein the system comprises:\n a first gas cooler with temperature control for water knock out having an inlet and an outlet; a first separator having an inlet, a liquid phase outlet and a gas phase outlet, the inlet of the first separator being in fluid communication with the outlet of the first gas cooler; a second gas cooler for water knock out having an inlet and an outlet, said second gas cooler inlet being in fluid communication with the gas phase outlet of the first separator; a second separator having an inlet, a liquid phase outlet and a gas phase outlet; wherein the outlet of the second gas cooler is in fluid communication with the second separator inlet; an addition point for hydrate inhibitor between the first separator gas phase outlet and the second separator inlet, the second gas cooler being downstream from the addition point for hydrate inhibitor; a third separator having an inlet, a liquid phase outlet and a gas outlet, wherein the second separator gas phase outlet is in fluid communication with the inlet of the third separator; and an addition point for adding further hydrate inhibitor between the second separator gas phase outlet and the third separator inlet while keeping the fluid above a hydrate formation temperature thereof such that further drying of the gas phase from the second separator is achieved by means of the further hydrate inhibitor.
