If a gas containing amino groups has an ammonia concentration of 38% and hydrogen sulfide concentration of 32%, at a flow rate of 500 Nm3/h, and if the hydrogen sulfide content in the cleaned acidic gas is 90%, also at a flow rate of 500 Nm3/h, what should be the mixing ratio between the cleaned acidic gas and the gas containing amino groups when feeding them into the burner?
Nitrogen-containing acidic gas enters through the nozzle; part of the clean acidic gas goes into the nozzle while another part is diverted to the middle part of the furnace, thereby keeping the temperature at the furnace tip above 1250 degrees Celsius.
With such a high concentration of ammonia, it shouldn’t be fed into any burner at all; try to recover it first. It is safer for the burner to tolerate less than 3 percent ammonia; even if the temperature is high enough to burn ammonia. The probability of the system having problems is very high. ,
