REMOVING MERCURY FROM CRUDE OIL

REMOVING MERCURY FROM CRUDE OIL

A method of determining mercury speciation in crude oil, comprising: a) adding isotopic mercury standards to a crude oil sample; 5 b) derivatizing all forms of mercury in said crude oil sample, wherein 10 pl of 2M ethylmagnesium chloride (EtMgCl) in THF and 0.5-1 ml of ultrapure heptane are added to...

Zusammenfassung:A method of determining mercury speciation in crude oil, comprising: a) adding isotopic mercury standards to a crude oil sample; 5 b) derivatizing all forms of mercury in said crude oil sample, wherein 10 pl of 2M ethylmagnesium chloride (EtMgCl) in THF and 0.5-1 ml of ultrapure heptane are added to the crude oil sample and allowed to react at 00 C for 20 minutes; c) separating derivatized mercury forms based on boiling points in a GC; and d) determining concentration of derivatized mercury forms based on relative 10 concentration to isotopic mercury standards using ICP-MS.
