Process, method, and system for removing heavy metals from fluids

摘要: Trace element levels of heavy metals such as mercury in crude oil are reduced by contacting the with an iodine source, generating a water soluble metal complex for subsequent removal from oil. In one embodiment, source is generated in-situ oxidation-reduction reaction, adding to species having charge and reductant or oxidant depending on species. embodiment positive reducing reagent, complexing agent also added extract into phase form complexes which can be separated oil, treated metals.
