Abstract
<p>Las instalaciones de hidroprocesamiento pueden operar durante períodos de tiempo prolongados antes de la detección de mercurio en las instalaciones de entrada, conforme el mercurio se adsorbe sobre las tuberías metálicas (100) utilizadas para transportar los fluidos de hidrocarburos, por ejemplo, gas, aguas producidas, desde los pozos hasta las instalaciones de procesamiento (“líneas de flujo"). Una vez que las tuberías (100) se “saturan” de mercurio, el mercurio aparecerá y se detectará en las instalaciones de entrada. Se describe un esquema de gestión/control de mercurio en donde se utiliza una etapa de tratamiento químico o térmico para limpiar la tubería, administrando la acumulación de mercurio en la tubería para una concentración reducida de mercurio en el fluido que sale de las líneas de flujo. El calentamiento durante la etapa de tratamiento térmico se realiza usando cualquier de un tratamiento con láser, un dispositivo de combustión o una bobina de inducción. Durante la etapa de tratamiento químico, se utiliza una solución acuosa de sulfuro que comprende al menos 0,1% en peso de un sulfuro, un polisulfuro o una combinación de los mismos.</p><p> Hydroprocessing facilities can operate for extended periods of time before the detection of mercury in the inlet facilities, as mercury adsorbs on the metal pipes (100) used to transport hydrocarbon fluids, for example, gas , produced water, from the wells to the processing facilities ("flow lines"). Once the pipes (100) are "saturated" with mercury, the mercury will appear and be detected at the inlet facilities. Mercury management / control scheme where a chemical or thermal treatment stage is used to clean the pipe, administering the accumulation of mercury in the pipe for a reduced concentration of mercury in the fluid that flows out of the flow lines. during the heat treatment stage it is performed using any of a laser treatment, a combustion device or a coil of Induction During the chemical treatment stage, an aqueous solution of sulfide is used comprising at least 0.1% by weight of a sulfide, a polysulfide or a combination thereof. </p>
