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 44):
A method for dehydration of a gas phase, the method comprising the steps of:\n receiving a first gas phase; cooling the first gas phase to condense out water, and optionally a hydrocarbon condensate, while keeping the first gas phase above a hydrate formation temperature thereof; separating off condensed liquids and a second gas phase from the first gas phase, the second gas phase having a lower water dew point than the first gas phase, adding a hydrate inhibitor to the second gas phase; cooling the second gas phase after mixing with the hydrate inhibitor to condense out water, and optionally a hydrocarbon condensate, while keeping the second gas phase above a hydrate formation temperature thereof; separating off condensed liquids and a third gas phase from the second gas phase, the third gas phase having a lower water dew point than the second gas phase; adding a hydrate inhibitor to the third gas phase; and separating off condensed liquids and a fourth gas phase from the third gas phase; wherein the fourth gas phase has a lower water dew point than the third gas phase; and wherein the hydrate inhibitor added to the third gas phase has a water content that is low enough to enable it to dry the third gas phase so that the fourth gas phase is able to satisfy pipeline transport specifications.
