Abstract
Continuous process for regasifying a feed stream having (i) a slurry phase comprising gas hydrate particles suspended in a produced liquid hydrocarbon and optionally free produced water and (ii) optionally a gaseous phase comprising free produced gaseous hydrocarbon thereby generating a regasified multiphase fluid and for separating the regasified multiphase fluid into its component fluids. The method includes (a) heating the feed stream to above the dissociation temperature of the gas hydrate thereby regasifying the feed stream by converting the gas hydrate particles into gaseous hydrocarbon and water, (b) separating a gaseous hydrocarbon phase from the regasified multiphase fluid thereby forming a gaseous hydrocarbon product stream and a liquid stream comprising a mixture of liquid hydrocarbon and water, (c) separating the liquid stream comprising a mixture of the liquid hydrocarbon and water into a liquid hydrocarbon phase and an aqueous phase; and (d) removing the liquid hydrocarbon phase as a liquid hydrocarbon product stream. The regasification production facility additionally has a concentrator vessel and the feed stream is passed to the concentrator vessel prior to being he…
