Oxidation furnace, incinerator
Thread Content
I was wondering if anyone has encountered projects involving exhaust gas containing around 10% CO, where such gas has little utility – it may not ignite if released directly. Heat recovery is being considered as a solution, and some suggest that TO or RTO systems can be used for processing this gas while recovering heat. I’m looking for any similar project examples; any help would be appreciated.
What air volume? This concentration can be diluted; it works either with an RTO + boiler or a TO + boiler
It has a large gas capacity, of 30,000–40,000 Nm3/h; using it to burn mixed natural gas would be rather wasteful and result in high operating costs.
The gas volume is approximately 35,000 Nm3/h+. It is said that the purge gas used in the ammonia synthesis industry has a composition similar to this; the main difference is that in that case CO2 is one of the main components, while in this case N2 is the main component. Having no experience with similar engineering projects, I was told by the supplier that in some ammonia synthesis plants, the blast gas is used in combination with vent gas for combustion in a TO+boiler configuration.
Gas with this concentration should be able to burn directly; the RTO furnace is likely not capable of handling it, as the heat generated is quite high. The best approach should be to recover CO through PSA.
What is PSA? Could you explain it?
CO itself originates from converter gas in steel plants; wouldn’t using PSA for its adsorption and recovery result in high costs?
We usually use diesel grade 0 for combustion, but the boiler needs to be of a larger size
