What is the reason for the high hydrogen sulfide level after desulfurization?
Thread Content
Our company uses the PDS wet desulfurization technology. Recently, the hydrogen sulfide level after desulfurization has been on the high side at 70 mg/m3 (the normal level is below 30). What factors are related to this situation? ?
How many do you design? PDS desulfurization is 70, which isn’t high; ours is over 200. How do you handle your by-product salt? If the desulfurization liquid is not treated, by-products will gradually accumulate, which will severely affect the desulfurization efficiency; this issue may become even more severe in the future
For desulfurization using the PDS method, our design requires a level of 300 mg/m3 or less. If I’m not mistaken, could the original poster share some of their experience in this regard?
Is there a PDS desulfurization process flow diagram? I want to learn * a bit.
1. Measure the alkalinity of the desulfurization solution to determine whether it meets the standards. 2. Assess the regeneration efficiency of the desulfurization solution as well as the amount of suspended sulfur in it. 3. Calculate the sulfur production to see if all the sulfur present in the gas can be extracted. The sulfur extraction process is also very important. 4. Additionally, check whether the reaction temperature in the desulfurization tower is around 30 degrees. 5. An excess of double salts can poison the catalyst; in such cases, some of the desulfurization solution must be discharged
