The problem of high pressure difference in the desulfurization tower during its initial operation.
Thread Content
Hello, esteemed seniors! We are facing a problem at the initial stage of debugging: when the gas flow rate is low, a large pressure difference appears across the desulfurization tower. What are the common causes of this? How to solve it. The gas volume is approximately 400 Nm3/h, the hydrogen sulfide concentration is 3500 ppm, the circulation rate is about 50 m3/h, the tower diameter is 1.2 m, and the packing used is DN50 eco-friendly ball packing.
The slurry sedimentation is significant. Air blockage. Or there’s a problem with the filler.
I haven’t carried out desulfurization for a long time; it seems that the issue lies in the placement of the filler – either its height is too high or it isn’t placed according to the specifications； Check the pipeline valves again
There is no precipitation in the liquid at the initial stage. The air isn’t blocked. What problems with filler installation can cause this?
7m high filler, in two layers. There is a distributor at the top, and a redistributor in the middle of the packing.
The pipeline valves should be fine. When the liquid circulation volume decreases, the pressure difference becomes smaller.
If the filler is not installed properly, uneven pressure will occur
