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.
