Desulfurization process
Thread Content
I would like to consult the seniors regarding the desulfurization process. Firstly, the gas source is the gas from the boiler flue; if it is compressed directly, the levels of sulfur compounds in the resulting gas will exceed acceptable limits, affecting its usability. There is no restriction on the location of desulfurization; as long as the desulfurization effect is good, that is sufficient. For example, desulfurization can be carried out before further compression, at a pressure of approximately ≤1 bar and a temperature of 30-45 degrees℃ ； Desulfurization can also be carried out after compression; the gas pressure after compression is 22 bar, and the temperature is 30–45°C. What type of equipment is generally used for desulfurization under these two conditions? What filler? Which one is better? What method is used for regeneration?
Desulfurization before compression can be carried out using the semi-dry method
The semi-dry method uses lime. I recall that in water treatment processes, molecular sieves can be used for removal; once saturated, these molecular sieves can be regenerated and reused, thereby saving costs. Is there a similar process for desulfurization? Can activated carbon meet the requirements for desulfurization?
There is utilization of recycled activated carbon, and there are similar cases in Inner Mongolia
What is the difference between semi-dry and wet methods?
Senior, could you give some advice? I’ve been looking for activated carbon with such functions lately, but haven’t found much! ! ! ! !

It involves using activated carbon to remove hydrogen sulfide, sulfur dioxide, and other sulfides from the gas; the level of sulfur dioxide is required to be less than 1 ppm, while hydrogen sulfide should be below 0.1 ppm
