Embodiment 1
[0020] Mix triazine derivatives 1, 3, 5-s-triazine solution and aminotrimethylene phosphonic acid uniformly at a ratio of 17:3 by volume, and add methyl sulfide (mainly Exist in the gas phase) and the production liquid device, measured after a period of time, the removal rate of methyl sulfide in the gas phase was 42.8%, the removal rate of methyl sulfide in the liquid phase was 44.3%, and the scale inhibition rate was 96.5%. The COD value of the product measured by potassium permanganate is 359ppm, which meets the third-level standard of GB8978 sewage comprehensive discharge. The removal rate of methyl sulfide in the gas phase is 43.4% in the spray method, 44.5% in the liquid phase, and the scale inhibition rate is 96.4%. The measured product COD The value is 332ppm.
[0021] Triazine derivatives 1, 3, 5-s-triazine solution and aminotrimethylene phosphonic acid are uniformly mixed according to the volume percentage of 17:3. Gas phase) and produced liquid device, measured aft...
Embodiment 2
[0023] Mix triazine derivatives 1, 3, 5-s-triazine solution, aminotrimethylene phosphonic acid and ethylenediaminetetraacetic acid according to volume percentage 17:2:1 and mix evenly. The form of injection is added to the device containing methyl sulfide (mainly in the gas phase) and the production liquid. After measurement, the removal rate of methyl sulfide in the gas phase is 51.3%, while the removal rate of methyl sulfide in the liquid phase reaches 99.7% %, the scale inhibition rate reached 91.0%, and the COD value of the product measured with potassium permanganate was 67ppm after filling; with the same ratio, the injection containing methyl sulfide (mainly in the gas phase) and the extracted In the liquid device, it has been measured: the removal rate of methyl sulfide in the gas phase is 99.9%, the removal rate of methyl sulfide in the liquid phase is 99.8%, and the scale inhibition rate is 90.9%. After filling, it is measured with potassium permanganate The COD value...
Embodiment 3
[0027]Mix triazine derivatives 1, 2, 4-triazine solution, aminotrimethylene phosphonic acid and sodium ethylenediamine tetraacetate according to the volume percentage of 15:4:1 and mix evenly. Filling into the device containing methyl sulfide and production fluid, it is determined that the removal rate of methyl sulfide in the gas phase is 51.3%, the removal rate of methyl sulfide in the liquid phase reaches 99.8%, and the scale inhibition rate reaches 97.5%. After filling, measure the COD value of the product with potassium permanganate to be 61ppm; triazine derivatives 1,2,4-triazine solution, aminotrimethylene phosphonic acid and sodium ethylenediaminetetraacetic acid are in the same proportion, using The form of spray injection is added to the device containing methyl sulfide and production fluid. After measurement: the removal rate of methyl sulfide in the gas phase is 99.8%, the removal rate of methyl sulfide in the liquid phase is 99.8%, and the scale inhibition rate It...
