Can sodium carbonate plus PDS desulfurization achieve a post-tower hydrogen sulfide content of less than 20?
Thread Content
For example, there is a new coking plant under construction. The desulfurization adopts the alkaline desulfurization process. The hydrogen sulfide content entering the tower is required to be 8000 and the output of the tower is less than 20. It feels a bit unreliable. Hope everyone can help. Thanks.
If the process design is reasonable, it can be achieved.

It is indeed difficult to achieve desulfurization in a single tower, but it is very easy to connect two towers in series.
Achievable! It depends on the equipment and design! What you said is unclear. According to the standard design, generally the two towers can be taken off. For specific communication, please add QQ: 88790043
A single tower can also be mainly determined by tower diameter, flow rate, catalyst, gas volume, etc. We have a single tower here
I agree with the sixth floor, it should be okay. As long as the design is reasonable and based on data such as gas volume, hydrogen sulfide content, diameter of the desulfurization tower, etc., it is completely possible to connect two towers in series or three towers in series.

We operate a three-tower turbulent ball tower plus two desulfurization towers in series. The subsequent section is methanol.
Brother, I disagree with this. There is a big gap between reality and theory, and this also requires reference to the height of the desulfurization tower, the number of trays, and many other things.
