Abstract:

This paper analyzes a practical application of ABC control system in the sulfur recovery unit of Claus furnace in coal chemical industry.The result demonstrates that the ABC control system is able to quickly adjust the distribution of air ratio for precise supply of air and oxygen whenever the working condition changes so as to ensure a stable operation of the sulfur recovery unit,with sulfur recovery rate of 95%~99%.The ABC control system has been proven to be high level automation,beneficial to natural and working environment.
