CNOOC Dongying Petrochemical Co., Ltd project
This project adopts the Integrated EADS technology independently developed by JNEP in 2 million tons / a heavy oil catalytic cracking unit' s tail gas treatment.
CNOOC Dongying Petrochemical Co., Ltd. 2 million T / a heavy oil catalytic cracking unit upgrading and supporting project adopts the FCC tail gas integrated treatment technology developed by JNEP.
Under the design condition of flue gas 298500 Nm3/h and inlet SO2 concentration 1914 mg/Nm3 JNEP' s technology can ensure desulfurization efficiencyĦŬ95.7%. SO2 in flue gas after desulfurization is not higher than 100mg / Nm3, and total dust in flue gas after desulfurization is not higher than 20mg / Nm3.The flue gas after desulfurization meets the requirements of the emission concentration of sulfur dioxide, nitrogen oxides and total dust in FCC tail gas in gb31570-2015 emission standard of pollutants for petroleum refining industry
