摘要： Hydroprocessing facilities may operate for extended periods of time before detection of mercury in the inlet facilities, as mercury adsorbs onto the metallic pipelines (100) used to transport the hydrocarbon fluids, e.g., gas, produced waters, from the wells to processing facilities ("flowlines"). Once the pipelines (100) become "saturated" with mercury, mercury will break through and be detected at the inlet facilities. A mercury management /control scheme is disclosed wherein either a chemical or a thermal treatment step is used to clean the pipeline, managing mercury accumulation in the pipeline for a reduced mercury concentration in the fluid exiting the flowlines. The heating during the thermal treatment step is done by using any of laser treatment, a combustor, or an induction coil. During the chemical treatment step an aqueous sulfidic solution comprising at least 0.1 wt. % of a sulfide, a polysulfide or a combination thereof is used.
