Which is more mature: the alkaline method or the ammonia method for treating sulfur recovery exhaust gases?

Which is more mature among the alkaline and ammonia-based methods for treating sulfur recovery exhaust gases? 1. Two-stage Claus process + hydrogen reduction + exhaust gas combustion + post-treatment with alkaline washing before emission. 2. Oxygen-enriched combustion + two-stage Claus process + exhaust gas combustion + composite amine method for SO2 removal. 3. Oxygen-enriched combustion + two-stage Claus process + selective reduction + selective oxidation technology + exhaust gas combustion + ammonia water absorption for sulfuric acid production
Our process consists of conventional Claus process + three-stage conversion + incineration + alkaline desulfurization. It has been in operation for 8 months now, with all online parameters being within acceptable limits and stable performance.
All three processes can meet the requirements; the specific process to be used depends on the current situation of your company. Firstly, no new hazardous waste must be generated, the load on wastewater treatment plants must not increase, and the working intensity of employees must not be increased excessively. Once again, process operations should be automated as much as possible. Finally, the operation site must be clean and free of odors.
Are there any materials on exhaust gas treatment for these three processes?
It is also necessary to calculate the operating costs of these three processes at a plant load of 50%. Look, that setup has a low cost. By combining those three points I mentioned above, it becomes possible to decide which process to adopt. :lol:lol:lol:lol Just my personal opinion
For the first type, is it widely used?
Both the alkaline method and the ammonia method are technically mature, each with its own advantages; the key factors are the price of raw materials and whether wastewater treatment can be properly managed
