ABSTRACT:
Carbon black process control system wherein in the preferred embodiment responsive to a determination of the humidity or water content in the free oxygen-containing gas flowing into the carbon black reactor two separate modes of control are calculated and a selection between the modes is made depending upon the influence each of the modes has on further properties of the overall operation. For example, the iodine number of the carbon black is controlled by either manipulating the air flow or the oil flow into the carbon black reactor to maintain the iodine number constant despite changes in the humidity and the selection between the two control modes (air flow control or oil flow control) is made in accordance with a determination of the respective conversion achieved.
