  • Method and apparatus for removing hydrate plugs
    Patent number: 9303488
    Abstract: A method for removing hydrate plugs in a hydrocarbon production station, the method comprising: fluidically isolating the production station; diverting production flow to a bypass line; and adjusting the pressure in the production station to a level sufficient to melt the hydrate plugs.
    Type: Grant

  • APPARATUS FOR THERMAL MANAGEMENT OF HYDROCARBON FLUID TRANSPORT SYSTEMS
    Publication number: 20150167888
    Abstract: Apparatus for thermal management of a hydrocarbon fluid transport system, the apparatus comprising means adapted to maintain the temperature of hydro-carbon fluid in the transport system at a temperature above the temperature at which hydrocarbon hydrates will form. Heat loss between a valve body (1) and its actuator (11) can be reduced by insulating the stem (13) connecting them. A trap (65) for warm water can be used around a pipeline to reduce heat loss due to convection. A pump or compressor can be thermally connected to bypass line so as to be effectively thermally one unit.
