Why does tar vacuum exhaust contain sulfur dioxide and carbon monoxide?
Thread Content
The tar processing unit employs vacuum distillation without the use of alkali. The vacuum exhaust gases from the tar production process, as well as the waste gases from the unit’s processes and from the storage tanks in that area, are combined together. Tests on the composition of this mixed gas revealed that the sulfur dioxide concentration was above 400 mg/m3, the carbon monoxide concentration was above 590 mg/m3, while the oxygen concentration was around 15% I would like to ask the experts: how are sulfur dioxide and carbon monoxide formed?
When tar is heated to 330 degrees, polymerization occurs; the separation of side chains results in the formation of sulfur dioxide, carbon monoxide, methane, water, and other substances
Thank you. I used to think it contained things like hydrogen sulfide, and not sulfur dioxide
