Se separan niveles de trazas de mercurio en un gas natural en una planta de procesamiento una unidad amina y/o un deshidratador. La separación del mercurio sucede de forma simultánea con la separación de gases ácidos en una unidad amina, por ejemplo, un absorbedor o un depurador, con una solución de amina que contiene un agente complejante. La separación del mercurio también puede realizarse de forma simultánea con la separación de agua en un deshidratador de glicol con el agregado de un agente complejante a la solución de glicol. El mercurio volátil en el gas natural se separa mediante el agente complejante, formando especies de mercurio no volátil en la solución de amina rica / glicol rico.Trace levels of mercury are separated into a natural gas in a processing plant, an amine unit and / or a dehydrator. The separation of mercury occurs simultaneously with the separation of acid gases in an amine unit, for example, an absorber or a scrubber, with an amine solution containing a complexing agent. The separation of mercury can also be carried out simultaneously with the separation of water in a glycol dehydrator with the addition of a complexing agent to the glycol solution. The volatile mercury in natural gas is separated by the complexing agent, forming non-volatile mercury species in the rich amine / rich glycol solution.
