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 heated in step (a) to above the dissociation temperature of the gas hydrate particles wherein a gaseous phase comprising free gaseous hydrocarbon separates from the feed stream in the concentrator vessel and is removed from the concentrator as a gaseous hydrocarbon stream.

A method and a system for transporting a flow of fluid hydrocarbons containing wax and/or asphaltenes or any other precipitating solids through a treatment and transportation system including a pipeline are disclosed. The flow of fluid hydrocarbons is introduced into a reactor (), where it is mixed with another fluid flow having a temperature below a crystallization temperature for the wax and/or asphaltenes or other solids and containing particles or crystals acting as nucleating and/or growth cores for the wax and/or asphaltenes or other solids, the mixing temperature providing precipitation of the wax and/or asphaltenes or other solids from the flow of fluid hydrocarbons, and the effluent flow of hydrocarbons and particles is conveyed from the reactor () to a pipeline () for transportation.

A composition for preventing or retarding the formation of gas hydrates during the transport of a fluid comprising water and a hydrocarbon through a conduit. The composition is a homopolymer of vinyl caprolactam, or copolymers thereof, having a low molecular weight in the range of 500 to 2500, which is made in a polymerization solvent, preferably a glycol ether, most preferably 2-butoxyethanol and also including a carrier solvent, preferably monoethylene glycol.
