摘要： A system to prevent the formation of hydrates in a pipeline includes a heater assembly. The heater assembly has a vortex tube mounted on an outer surface of a first section of the pipeline and a compressed gas source. The vortex tube is configured to separate gas from an inlet into a hot gas pathway and a cold gas pathway. The vortex tube includes an inlet, a cold gas outlet, and a hot gas outlet. The hot gas outlet of the vortex tube is fluidly connected to an opening defined in the first section of the pipeline. The hot gas outlet is configured to flow hot gas from the vortex tube into an interior volume of the pipeline. The compressed gas source is fluidly connected to the inlet of the vortex tube.
