Abstract: A new process technology for treatment of VOCs by using FCC regenerator in normal production state of refinery was developed, which is used for high efficiency and low energy consumption treatment of VOCs with different concentrations and types discharged from different pollution sources of refinery. By controlling the concentration and temperature of VOCs waste gas entering the regenerator, and applying high grade flame arrester, one-way valve and other safety measures, the safety of VOCs waste gas transportation and treatment process was ensured. Due to the catalytic oxidation performance of heavy metals deposited on the surface of catalytic cracking catalysts, the developed technology has a good VOCs removal effect at a relative low combustion temperature (670 - 720℃). The industrial applications showed that after the treatment the VOCs concentration in the flue gas was less than 10mg / m3, which fully meets higher requirements of SINOPEC control standard for VOCs（no more than 15mg/m3）. Meanwhile, the technology had no impact on the normal production of FCCU, product properties, and desulfurization and denitrogenation of regenerator flue gas.
