ABSTRACT:
In a carbon black manufacturing process in which an off-specification rerun carbon black is mixed with the carbon black flowing from a carbon black reactor to produce a combined carbon black stream, method and apparatus is provided for controlling the carbon black process so as to insure that the combined carbon black stream will meet predetermined specifications. The feed flow to the carbon black reactor is controlled in response to a comparison of a prediction of the actual surface area of the combined carbon black stream with the desired surface area of the combined carbon black stream so as to provide a combined carbon black stream made up of carbon black particles which have a desired surface area. The flow of potassium to the carbon black reactor is controlled in response to a comparison of a prediction of the structure of the combined carbon black stream with the desired structure for the combined carbon black stream so as to produce a combined carbon black stream in which the aggregated carbon black particles have a desired structure.
