Removal of Nickel and Vanadium from Crude Oil by Microwave-Chemical Method. I. Chemical Method

摘要

WY series demetalizers, some types of thiocarbamate, were synthesized by organic amine (diethylene triamine and triethylene tetramine), carbon disulfide, and sodium hydroxide and used to remove nickel and vanadium from crude oil. WY-1 demetallizer has excellent removal of nickel and vanadium efficiency for Shengli crude oil and Iran crude oil. The nickel and vanadium removal efficiency of Shengli crude oil reached 43.41 and 41.63% at the dosage of WY-1 500 mg/L, reaction lime 30 min, and reaction temperature 70°C. With the dosage of WY-1 and increasing reaction time and reaction temperature, the nickel and vanadium removal efficiency of crude oil increased.
