ABSTRACT:
In a carbon black manufacturing process in which a carbon black dryer is utilized to produce a product carbon black having a specified dryness, method and apparatus is provided for controlling the flow of fuel to the carbon black dryer so as to insure that the dryness of the carbon black product will meet predetermined specifications. Feedforward, predictive control of the flow rate of the fuel to the carbon black dryer is utilized to compensate for changes in the flow rate of wet carbon black or for changes in the moisture content of the wet carbon black. In this manner, the dryness of the carbon black product is maintained at a predetermined specification even though process variations may occur.
