Would you consider using power wave tail washing to treat the SO2 emissions from the Claus unit?

The absorbents can be hydrogen peroxide, alkalis, ammonia, etc. There are many successful applications in practice, especially in the treatment of exhaust gases from sulfuric acid production plants. The investment and operating costs are not high either; what’s important is that the system can operate stably over the long term. Would you consider such a method for treating exhaust gases? There are currently many different technical solutions for exhaust treatment in Kraus systems. What solutions do you plan to use for your devices?
What should be done with the washed alkaline residues, sodium sulfate, and things like that?
This is a problem that solvent absorption processes commonly face; it is not an isolated case. Therefore, the choice of absorbent should be determined based on the specific circumstances of the enterprise. While ensuring that emissions meet the required standards, it is also necessary to make use of the resulting sulfates as much as possible; otherwise, gaseous waste is merely converted into solid waste.
Yes. As far as I know, if MDEA is used for absorption, the amount of waste alkaline solution is not large; however, when alkali washing is used, the amount of alkaline solution is very large. The difficulty of these two treatments differs significantly when compared to each other.
Alkalis are expensive, and their absorption efficiency is good, but treating with sodium sulfate is difficult; nowadays, alkalis are used less and less directly, while the ammonia method presents problems related to aerosols. Who can explain in detail the general process for MDEA-based desulfurization and decarbonization? How is absorption carried out, how is the reaction carried out, and what happens to the acidic gases produced as a result of this process?
It is technically feasible, but it’s not necessary – can the characteristics of power waves be utilized in this context?
Which marine user has implemented ammonia-based desulfurization for sulfur-containing exhaust gases, and what are the results? What are the problems, and what impact do they have on the device? Please let us know if we are considering using the ammonia-based desulfurization method
Power waves enhance the gas-liquid mass transfer process, allowing the diameter of the tower to be reduced. The material used is a concern, and both the effectiveness and cost-effectiveness of this approach still need to be verified.
The ammonia-based desulfurization technology for sulfur-containing flue gas is feasible, and there are existing engineering examples; however, there are indeed some aspects that need attention during the design process.

The absorbents for kinetic wave technology can be diverse; ammonia can certainly be used as an absorbent as well. The equipment required is minimal, and the economic costs are not as high as one might think. The system design is simple, and operation and maintenance are straightforward. It can also handle large fluctuations in the volume and concentration of flue gas. Even during startup, shutdown, or maintenance, it is possible to bypass the entire Claus system or exhaust gas treatment system, thereby ensuring that the levels of SO2 in the exhaust gases do not exceed permissible limits. The frequency of shutdowns for maintenance is also low. In my opinion, compared to traditional packing spray washing methods, kinetic wave technology has clear advantages.
