Abstract:

The working principle, simple process, main start-up steps and operation precautions of RTO regenerative oxidation device are introduced. The RTO regenerative oxidation device is used to recover and treat the exhaust gas of the low-temperature methanol washing device and the exhaust gas of the water treatment device. The mass concentrations of non-methane total hydrocarbons, NOx, methane, and SO2 in the exhausted flue gas are 20.7, 1.0, 2.3, 1.0 mg/ m3, and HCN should not be detected; all indicators should also meet the emission requirements of the national standard "Emission standard of pollutants for petroleum chemistry industry" (GB 31571—2015), and 90 t/h superheated steam of 1.5 MPa, 240 ℃ is obtained as a by-product. The actual operation results show that the RTO regenerative oxidation device has achieved the purpose of energy saving and consumption reduction for coal chemical enterprises.
