Catalytic flue gas desulfurization
Thread Content
How is the salt generated by catalytic cracking flue gas desulfurization disposed of?
If the falling film gas-liquid contact exchange crystallization process is put into use, the original poster should remember to share their experiences with it.
It should be sent to the crystallization tank for crystallization treatment; after the concentration is reduced, it can then be sent to the wastewater treatment plant for further processing.
How is that method using calcium hydroxide progressing? It seems to be the modified calcium method.
Is this the current trend? Salt must be treated; we currently discharge wastewater directly to the treatment plant without carrying out any treatment
Are there any local restrictions on the salt content in wastewater? If so, evaporation crystallization is used. . .
Sodium sulfite is oxidized to sodium sulfate; if it goes to a wastewater treatment plant, the high salt content and high electrolyte levels there can affect wastewater treatment. By catalyzing the passage of flue gas through subsequent wastewater treatment processes, the levels of COD, suspended solids, and ammonia nitrogen are reduced to such an extent that the water can be discharged directly outside.
What kind of water do everyone use for rehydration? Why?
It turns out the original poster was referring to the flat-sheet filter membrane crystallization technology – have you put it into use yet?
The essence is the same; it’s just that, according to the poster’s description, the calcium method tends to cause scaling. His approach, however, is to address the possibility of scaling within the salt-containing wastewater treatment system.
