Abstract
Vanyukov's process of extraction is an autogenous method for sulfide concentrates of nonferrous metals. Melting is accomplished in a specially designed furnace and is accompanied by generating sulfur dioxide bearing off-gases. Different sulfur removal methods are used to reduce sulfur dioxide emissions into the atmosphere, of which the Claus process is the most significant process of gas desulfurizing. The efficiency of a typical Claus process can achieve as much as 80% of sulfur recovery. However, the existing control system enables achievement of not more than 60- 70% efficiency due to lack of an adequate process model. The paper presents an automated control system which is based on a fuzzy model of sulfur dioxide recovery.
