1. A method for transporting a hydrocarbon through a pipeline, comprising:
injecting water into a production stream at a production center, wherein the production stream comprises a hydrocarbon, and wherein the water injection forms a transportation stream comprising a water external phase; promoting the formation of hydrates around oil droplets and hydrates around gas bubbles, wherein the gas bubbles comprise light hydrocarbons, wherein the hydrates, oil droplets, gas bubbles, and water form a transportable hydrate slurry, and wherein promoting comprises:
creating the transportable hydrate slurry, wherein creating comprises flowing the transportation stream through a static mixer;isolating wax in the oil droplets by cooling the transportable hydrate slurry below a wax appearance temperature or a hydrate formation temperature, wherein cooling comprises contacting the transportable hydrate slurry with the pipeline, flowing the transportable hydrate slurry through a heat exchanger, or both; andmaintaining the transportable hydrate slurry, wherein maintaining comprises:
flowing the transportation stream through a plurality of static mixers;monitoring a phase behavior of the transportation stream, the size of the hydrate particles, or both; andcontrolling the phase behavior in the transportation stream by adding a thermodynamic hydrate inhibitor to keep the water external phase, and wherein the thermodynamic hydrate inhibitor suppresses capillary attractive forces between hydrate particles; and flowing the transportation stream through a transportation line to a surface facility. |
