Embodiment 1
[0026] process such as figure 1 As shown, the sulfur recovery unit flue gas 1 (temperature is 315 ° C, SO 2 The content is 500mg / m 3 , O 2 Content is 3.2%) and S Zorb regeneration flue gas 2 (temperature is 125 ℃, SO 2 The content is 3.5%, O 2 The content is 3.8%) respectively into the catalytic cracking unit through the pipeline, mixed with the regeneration air 3 of the catalytic cracking unit introduced by the blower, and then introduced into the charred tank 4. In the coke tank 4, the catalytic cracking catalyst reacts with oxygen at a high temperature of 680°C to burn the catalyst and realize the regeneration of the catalyst. At the same time, the oxygen in the flue gas 1 of the sulfur recovery unit and the flue gas 2 of the S Zorb regeneration is reacted, The remainder contains SO 2 The gas is regenerated with the catalytic cracking flue gas, and the catalyst particles are separated through the cyclone separator provided in the regenerator 5 . The regenerated flue g...
Embodiment 2
[0029] process such as figure 1 As shown, the sulfur recovery unit flue gas 1 (temperature is 280 ℃, SO2 The content is 150mg / m 3 , O 2 Content is 5%) and S Zorb regeneration flue gas 2 (temperature is 160 ℃, SO 2 The content is 5%, O 2 content of 5%) are respectively introduced into the catalytic cracking unit through the pipeline, mixed with the regeneration air 3 of the catalytic cracking unit introduced by the blower, and then introduced into the charred tank 4. In the coke tank 4, the catalytic cracking catalyst reacts with oxygen at a high temperature of 720°C to burn the catalyst and realize the regeneration of the catalyst. At the same time, the oxygen in the flue gas 1 of the sulfur recovery unit and the flue gas 2 of the S Zorb regeneration is reacted, The remainder contains SO 2 The gas is regenerated with the catalytic cracking flue gas, and the catalyst particles are separated through the cyclone separator provided in the regenerator 5 . The regenerated flue ...
Embodiment 3
[0032] process such as figure 1 As shown, the flue gas 1 of the sulfur recovery unit (at a temperature of 350°C, SO 2 The content is 800mg / m 3 , O 2 Content is 2%) and S Zorb regeneration flue gas 2 (temperature is 110 ℃, SO 2 The content is 2%, O 2 content of 0.2%) are respectively introduced into the catalytic cracking unit through the pipeline, mixed with the regeneration air 3 of the catalytic cracking unit introduced by the fan, and then introduced into the charred tank 4. In the coke tank 4, the catalytic cracking catalyst reacts with oxygen at a high temperature of 650°C to burn the catalyst and realize the regeneration of the catalyst. At the same time, the oxygen in the flue gas 1 of the sulfur recovery unit and the flue gas 2 of the S Zorb regeneration is reacted, The remainder contains SO 2 The gas is regenerated with the catalytic cracking flue gas, and the catalyst particles are separated through the cyclone separator provided in the regenerator 5 .
