Abstract
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.
