Abstract

Carbon black is collected by producing a combustion gas containing particles of carbon black, by means of a combustion oven, aggregating the carbon black particles, collecting the aggregated particles on a bag filter, and forming the carbon black particles into the desired product. The use of a multi-stage cyclone is avoided, thus reducing the costs. The air velocity through the bag filter is about twice that of the usual processes. Less time is needed to clean the filter. Filtration resistance is greatly reduced. A small filtration surface can be used. The filter bag can be used for longer periods.
