Mercury removal with amine sorbents |
摘要 |
Methods and apparatus relate to treatment of fluids to remove mercury contaminants in the fluid. Contact of the fluid with an amine that has absorbed a sulfur compound causes the mercury contaminants to be absorbed by the amine. Phase separation then removes from the fluid the amine loaded with the mercury contaminants such that a treated product remains. |

1. A system comprising:
a gas stripper that transfers a sulfur compound from gas input into the gas stripper to a sulfur-lean amine input into the gas stripper and produces an output of a sulfur-rich amine; and a mercury removal unit that couples with the gas stripper to receive the sulfur-rich amine and introduces the sulfur-rich amine into contact with a mercury-containing hydrocarbon liquid input into the mercury removal unit to transfer mercury from the mercury-containing hydrocarbon liquid to the sulfur-rich amine, wherein the mercury removal unit includes first and second outlets disposed based on separation of a hydrocarbon phase and an aqueous phase within the mercury removal unit to produce through the first outlet a mercury loaded amine and produce through the second outlet a treated hydrocarbon liquid. |
