Petroleum Coke
Petroleum Coke

Calcination is a high temperature process for transforming the physical properties of raw petroleum coke Raw petroleum coke is stored in a closed shed then transfer to day bins for easy controlling of feed quality and fed into a rotary kiln in controlled ratios The calcination process raises the material temperatures in the kiln to around 1200 to 1300 deg C depending on the specification of C P Coke
