About Calcined Petroleum Coke
Calcined Petroleum Coke (CPC) is obtained by Calcining (Heating in presence of controlled Oxygen Air) Raw Petroleum Coke (RPC) at temperature as high as 14000C. RPC is the end product of the Oil refining process and derived from the fractional distillation of Petroleum Crude in delayed Cokers. CPC is mainly used in the Aluminium extraction, Graphite Electrode manufacturing, steel melting, Titanium Dioxide and other Carbon consuming industries.

Manufacturing Process:
Raw Petroleum Coke (RPC) received from the Refinery is sized and fed into a Kiln which may be rotary or Vertical shaft kiln. The coke gradually moves towards the lower end of the kiln and during its movement down the Kiln all moisture and volatile matters present in the RPC are driven off. It is a exothermic process with the burning of hydrocarbons present in the RPC providing the heat required for Calcination. The product received at the end of the process is a highly Electrically conductive Carbon called Calcined Petroleum Coke.
