Manufacturing Process of Mitsubishi Carbon Black
Manufacturing Process of Mitsubishi Carbon Black
Manufacturing process of Mitsubishi Carbon Black and products are described below.
Manufacturing flow of Carbon Black
1) Generating Carbon Black
Fuel and air are introduced into a special reaction chamber lined with fire-bricks with heat resistance of up to about 2000°C, and are completely burned to generate a high-temperature atmosphere of over 1400°C. Raw liquid oil (feedstock oil) is then introduced to thermally decompose it in order to generate carbon black.
2) Separating and Collecting Carbon Black
The generated carbon black is mixed with high-temperature gas. Water is sprayed onto it to quench the carbon black generating reaction, and then carbon black and exhaust gas are separated using a bag filter.
3) Processing to Bead (Pellet) Carbon Black
The separated carbon black is processed to increase its bulk density before being granulated.
There are two types of granulation methods, the wet granulation method using water as a binder and the dry granulation method with no water.
4) Packaging carbon black
Products stored in silos are packed into hopper trucks, flexible containers, or paper bags for shipment.
