Jiangnan Environmental Protection can reduce sulfur dioxide levels to below 50 PPm. 13655178567, Li
Some plants choose to add an alkaline scrubber behind the exhaust gas absorption tower of the sulfur treatment unit; the exhaust gas that has undergone further desulfurization then enters the incinerator, so that the exhaust gas released outside does not exceed the specified limits
I know that factory uses it; could you tell me more? I’d like to have the opportunity to investigate it
How to treat the wastewater after alkaline cleaning? The sulfide level is too high, and it contains sulfate ions; air stripping doesn’t work, and oxidation proceeds too slowly – how to deal with this?
There are various methods for treating sulfur-containing exhaust gases, which can be divided into two main categories: methods that involve installing devices before the incinerator to treat H2S, such as the complexed iron process, direct oxidation process, and ultra-purification process； Treatment facilities are added after the incinerator and before the flue gas enters the chimney, primarily to treat SO2, such as the Consox process and flue gas alkaline scrubbing processes. Personally, I believe devices for treating SO2 provide a better guarantee of meeting emission standards, by shielding against fluctuations in upstream operations as well as leaks and short circuits in the exhaust system valves.
You can hire a design firm to do it; this will require some investment
Hello, I am from Fluor in the United States. I saw that you are conducting research on sulfur recovery, and I would be interested in talking with you about it.
We have a wet oxidation recovery technology for complexed iron, which replaces the amine absorption process after the quench tower to directly produce sulfur.
At present, there are several sets of systems whose performance is stable (for example, Sinopec Liuhua Oilfield, Sinopec Yangzhou Petrochemical, Shandong Qiwanda, etc.). If you are interested, we can discuss this in more detail; QQ: 364760441
