ADDITIVE EFFECTS ON THE BEHAVIOR OF LIQUID FEEDSTOCKS IN CARBON-BLACKPRODUCTION PROCESS

A comprehensive investigation on the behaviour of the carbon black fee dstock at the different stages of preheating section of carbon black m anufacturing unit are reported. The results tends to emphasize the nee d to quantify the effect of thermal stress and demonstrate that the th ermal treatment leads to some physical as well as chemical transformat ion to the feedstock, which may affect the stability and compatibility of the system and consequently alter the end product quality. An atte mpt is also made to regulate the feedstock stability by adding two dif ferent industrial petroleum products as additives at different stages of preheating section of carbon black production unit. A possible rela tionship between feed properties, additive treatment and preheating co nditions is also defined.
