Excess oxygen in sulfur recovery
Thread Content
This post was last edited by liaifeng on 2018-9-2 14:55. Why does the temperature of the converter rise when there is an excess of oxygen in the sulfur recovery process? What causes the temperature in the converter to rise? Will raising it affect product quality? I would like to ask the experienced masters for a detailed answer
Do you mean the sulfur production reactor or the converter? If there is an excess of oxygen, both can cause overheating. When there is an excess of oxygen in the reactor, excessive sulfur dioxide is produced, and the release of large amounts of heat causes the temperature to rise. When there is an excess of oxygen in the reactor, it can cause the sulfur on the bed to oxidize or even burn, generating a large amount of heat, which ultimately leads to overheating of the reactor.
Thank you for your answer; I found it very helpful:handshake
The original designer arranged the air supply in a 2:1 ratio to ensure a satisfactory sulfur recovery rate; any excess air would then be used for combustion, which leads to an increase in temperature!
