Embodiment 1
[0050] The waste alkali solution produced by a corporate ethylene device, wherein the COD is 58000 mg / L, the sodium sulfide concentration is 2.9 wt% (S 2- : 12200 mg / L), the sodium carbonate concentration was 2.0 wt% (20500 mg / L), and the sodium hydroxide concentration was 1.6 wt%.
[0051] The main composition of the flue gas generated by a company is: CO 2 The content is 14V%, the NOx content is 0.06V% (90% of NO), SO 2 The content is 0.04 V%.
[0052] The flue gas is introduced into the desulfurization absorption tower, and the vinyl scrapper liquid is used as the absorbent, and the pH of the absorbent liquid is 5-6, and the portion of the desulfurization absorption liquid is absorbed outside the absorbent liquid. Start replenishing the waste alkali solution, when the pH reaches 6, stopping the completion to obtain desulfurized smoke. The draft desulfurization absorbing solution is mainly based on sodium sulfite, adding cooked lime to make the desulfurization waste liquid...
Embodiment 2
[0057] The waste alkali produced by a corporate ethylene device, wherein the COD is 33000 mg / L, the sodium sulfide concentration is 2.1% by weight (S 2- : 8831 mg / L), the sodium carbonate concentration was 1.1 wt% (11275 mg / L), and the sodium hydroxide concentration was 1.2% by weight.
[0058] The main composition of the flue gas generated by a company is: CO 2 The content is 10 V%, the NOx content is 0.04V%, so 2 The content is 0.03 V%.
[0059] The flue gas is introduced into the desulfurization absorption tower, and the vinyl discardium liquid is used as the absorbent, and the pH of the absorbent liquid is 5.5-6.5, and the pH is less than 5.5, and some desulfurization absorption liquid is outside. Start replenishing the ethylene waste alkali solution, when the pH reaches 6.5, stopping the completion to obtain desulfurization. The draft desulfurization absorbing solution is mainly based on sodium sulfite, adding cooked lime to make the desulfurization waste liquid to rege...
Embodiment 3
[0064] A certain enterprise propane dehydrogenated olefin produced by the waste alkali solution, wherein sodium sodium sulfide is 6.83 wt%, sodium hydrosulfide is 4.8% by weight, COD is 117300 mg / L, pH of 13.5.
[0065] The main composition of the flue gas generated by a company is: CO 2 The content is 20 V%, the NOx content is 0.05V%, so 2 The content was 0.02 V%.
[0066] The flue gas is introduced into the desulfurization absorption tower, and the propylene waste base liquid is used as the absorbent, and the pH of the absorbent liquid is 5-6, when the pH is lower than 5, the portion of the desulfurization absorption liquid is outside. Start replenishing the propylene waste alkali solution, when the pH reaches 6, stopping the completion, resulting in desulfurization. The draft desulfurization absorbing solution is mainly based on sodium sulfite, adding cooked lime to make the desulfurization waste liquid to regenerate, to obtain CASO 3 Presets, calcined by high temperature, ob...
