Single-stage counter-current anoxic complete regeneration!
Thread Content
I’ve just started learning about catalysis and don’t understand this way of catalyst coking. Isn’t oxygen-deficient regeneration done using a combustion furnace with CO? Why is this oxygen-deficient coking method related to waste heat boilers? Please provide some explanations!
It is confirmed to be oxygen-deficient; what is the oxygen level during normal production, 0?
I’ve read the operating procedures for this process, and it indeed specifies an oxygen-deficient environment; the required oxygen content level in the flue gas is between 1 and 4
That is regular full regeneration, with oxygen enrichment. The oxygen content at low oxygen levels is 0.5%. This kind of regeneration should result in very low NOX levels.
Well, I’ll ask the technicians in the workshop again to find out what’s going on
Whether in low-oxygen or high-oxygen conditions, the main function of a waste heat boiler is to generate steam using the thermal energy of the flue gases.
Yeah, but I really think I’ve seen somewhere that oxygen-deficient combustion is carried out first, followed by combustion in a CO furnace. I’m not sure if that’s correct
I think we should go to the flue gas extractor first, and then to the waste heat boiler. A CO combustion furnace and a residual boiler are not exactly the same concept.
