<p>A process for the production of carbon black comprising burning a fuel with preheated air in a reactor to obtain an off-gas containing carbon black particles, hot gases and stream, quenching the reaction with a cooling fluid to obtain an effluent, subjecting the effluent to a step of cooling by allowing the additoinal heat of smoke to dissipate into the atmosphere followed by a step of further temperature reduction by spraying with a second cooling fluid, and purification of the smoke, collecting the carbon black from the smoke, subjecting the same to pulverisation, densification and drying to obtain the carbon black.</p> |
