Abstract

Components of a chemical processing system are disclosed. In particular, a chemical processing system is disclosed which includes a chemical mixing or reacting zone, an inlet to the zone, an outlet to the zone, and a vacuum or fluid flow source located downstream of the outlet. The chemical processing system further includes means to control the amount of vacuum or fluid flow through the zone. Also disclosed is a continuous feeder system having a first loss-in-weight and a second loss-in-weight feeder and means for measuring a lower limit of feed in each feeder. There is also a means to activate the second feeder when the lower limit is obtained in the first feeder and means to deactivate the first feeder when the lower limit is detected in the first feeder. A sample port assembly is also disclosed for obtaining a sample of material flowing through a processing system. The sample port assembly includes a port in the assembly and a sample cup holder adapted to be moved in the port to obtain a sample of material without substantially affecting the fluid pressure or flow within the system. The components of the chemical processing system can be used in processes to make carbon black having attached organic groups.
