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.

Abstract: A method and system is provided for dehydration of a gas phase and hydrate inhibition of a liquid hydrocarbon phase in a produced multiphase hydrocarbon fluid stream containing water, comprising the steps of: 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; wherein the first gas phase has a water dew point which is lower than that of the initial multiphase hydrocarbon fluid stream and the second gas phase has a lower water dew point than the first gas phase; characterised in that the hydrate inhibitor has a water content that is low enough to enable it to dry the first gas phase, said hydrate inhibitor being separated off with the condensed liquids in step iii) and mixed with a part or all of the liquid phase from the separation in step i) to inhibit said liquid phase.

Abstract: Methods and apparatus for processing fluid from a well are described. A first wall portion may define a first region and a second wall portion may define a second region, fluid from said well being let through those regions. Heating of said first wall portion may be performed to release wax from said first wall portion into said fluid at said first flow region. During said heating, cooling of said fluid at said second flow region may be performed to cause wax from said fluid to deposit on said second wall portion.
