Analysis of Sulfur, Vanadium and Nickel in Crude Oil

29 Jul 2013

Sulfur, vanadium and nickel occur naturally in crude oil, and their concentrations vary depending on the geographical region of the oil deposits. Vanadium and nickel can foul the refining process during crude oil cracking, and so crude oil with low levels of vanadium and nickel is desirable. In the oil fields and in off-shore drilling, a quick and easy means of screening for vanadium and nickel is a valuable tool to begin to characterize the quality of the crude before refining. In this application note read how the NEX QC+ from Rigaku, allows monitoring of the concentrations of vanadium, nickel and sulphur in crude.
