What are the effects of using acidic steam for water stripping to purify water in catalytic cracking flue gas desulfurization?
It should have no impact; as long as it meets the emission standards, that’s sufficient.
We have used wastewater treated by a sewage treatment plant; the results were average, and foam appeared in the water when the COD level was high
When it comes to purified water, it depends on whether your COD level meets the discharge requirements; this limit must not be exceeded. Therefore, if the distillation process for treating wastewater is not very reliable, it is advisable to avoid using such a method.
Using purified water is very likely to cause the COD level in the desulfurization wastewater to exceed the allowable limits, as the COD contained in purified water cannot be degraded within the flue gas desulfurization system, and it becomes concentrated after passing through the scrubber tower
After using it for a while, the COD level became quite high; however, discharging the wastewater directly to the sewage treatment plant allows it to be treated to meet the required standards. It was stopped because the smell from the chimney was too strong
It is estimated that the poster aims to achieve energy savings through the reuse of wastewater; it’s a good idea. However, energy conservation often requires us to consider various aspects in a comprehensive manner – what are the benefits brought about by this measure? What are the disadvantages? How much is the additional equipment needed and what are the subsequent maintenance costs? Overall, are the advantages greater than the disadvantages, or are the disadvantages greater than the advantages? This is just like the feasibility study that must be conducted before the actual implementation of many projects!
