The feasibility of removal vanadium (V) from Iraqi crude oil using
zeolite A was investigated. Different operating parameters such as adsorbent
loading, vanadium loading, and operating time were studied for their effects on
metal removal efficiency. Experimental results of adsorption test show that
Langmuir isotherm predicts well the experimental data and the maximum zeolite A
uptake of V was 30 mg/g. XRD and EDX analyses revealed the noticeable uptake of
zeolite for V. In crude oil, experimental results indicated that for zeolite
loading at 1g/100ml oil and within approximately 5 h, the removal efficiencies
of V were 60, 45, and 33% at vanadium loadings of 75, 85, and 95 ppm
respectively. While at 10, 20, 40, and 50 h the removal efficiency was 68, 75,
78 and 78% for 75 ppm of V loading. The equilibrium concentration of V in crude
oil was attained after 40 h of operation. Long term
tests revealed the high stability of zeolite A for vanadium removal. Results
depict that zeolite A could be advantageous for removal of V in the crude oil
hydrotreating units.
