Carbon black process diagram

Furnace black manufacturing process summarized

Previously heated oil, gas fuel and high-temperature air are injected into a reactor creating high-temperature combustion gas.
Feedstock oil is atomized into this high-temperature combustion air, producing carbon black.
Later, cooling water is atomized to stop carbon black generating reaction.

Inside bag filters, carbon black and by-product gas are separated.
At this stage, carbon black is in powder form. It is then mixed with water inside a pelletizer and processed into pellets.

Carbon black stored in product tanks is packed according to customers needs in bulk (trucks or freight trains), flexible containers, etc., and transported.

By-product gas separated inside the bag filters is sent to the driers for reuse and to the power plant as fuel.
