The fluid catalytic cracking (FCC) process is one of the most important oil refining processes, in which heavy oil is converted to light fractions. The FCC catalyst regeneration generates flue gas containing SO2, NOx and particulates, and treatment before discharge is required to meet the emission regulations. The integrated FCC flue gas treatment technology offered by JET seamlessly integrates state-of-the-art SO2, NOx and PM control technologies, and provides an efficient and cost-effective solution to FCC flue gas treatment requirements.
