Name | Complex iron desulfurizer |
Synonyms | Complex iron desulfurizer |
The addition of the catalyst can be dissolved in soft water or desulfurization solution and added to the system. During the process of replacing the catalyst, the original device does not need to be discharged.
Desulfurization solution, only need to add desulfurization catalyst according to the plan.
1. The total amount of system desulfurization liquid is the most critical data for the use effect and cost. Therefore, the total amount of system desulfurization liquid should be estimated accurately to ensure the initial concentration of the catalyst.
2, the catalyst should swim light, moisture-proof storage, warranty period of 2 years.
3. After application, pay attention to monitoring the alkalinity of desulfurization liquid and the high distribution of sulfur foam. Due to the high sulfur capacity of the good chemical agent, the sulfur output of the system will increase, so attention should be paid to the processing capacity of the molten sulfur label.
4. Although the complex iron desulfurization technology has the ability to resist oil interference, a large amount of tar and washing oil brought into the desulfurization system will affect the normal foam flotation, so it is necessary to do a good job in the pretreatment of the gas entering the desulfurization system.
the oxidation and reduction of iron quotient is used to avoid the deep oxidation of h and s, reduce the generation of by-products thiosulfate and sulfate, reduce the external displacement of desulfurization liquid, and control the secondary salt.
The reaction is:
H,S 2Fe3 Ln-2Fe2 Ln41/85 2H
2Fe2 Ln l/2o2 H2O->2Fe3 1n 2HO
The total reaction is:
H2S l/2o2->l/8S3 2H2O
The reaction principle of complex iron technology, due to the existence of chelating agent, not only increases the solubility of iron ions, but also improves the stability of iron ions.
