A method for removing mercury from a natural gas stream comprising mercury wherein the method comprises:
- providing a mercury scavenging agent and a dehydrating agent;
- and
- contacting the natural gas stream comprising mercury with the mercury scavenging agent and the dehydrating agent under conditions to sequester at least a portion up to about all of the mercury from the natural gas stream.
A method for removing mercury from a natural gas stream comprising mercury wherein the method comprises:
- providing a copper sulfide and monoethylene glycol;
- and
- contacting the natural gas stream comprising mercury with the copper sulfide and monoethylene glycol under conditions to form a solid mercury complex;
- filtering the solid mercury complex from the natural gas stream;
- removing the monoethylene glycol from the natural gas stream;
- and
- distilling the monoethylene glycol to remove water.
A composition comprising:
- monoethylene glycol;
- water;
- a solid mercury complex comprising a reaction product of mercury and copper sulfide;
- and
- natural gas.
