Abstract:
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.
