  • Method and system for transporting flows of fluid hydrocarbons containing wax, asphaltenes, and/or other precipitating solids
    Patent number: 7261810
    Abstract: 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 (4), 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 (4) to a pipeline (6) for transportation.
    Type: Grant

  • Method for preventing or retarding the formation of gas hydrates
    Patent number: 6451892
    Abstract: 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.
