Abstract
The present disclosure relates to a process for the production of needle coke in a delayed coker plant. The needle coke so obtained by the process of the present disclosure has a co-efficient of thermal expansion (CTE) of less than 1.2×10/° C. The process of the present disclosure eliminates the step of hydrotreating of the first feed and second feed for the production of good quality coke. The process of the present disclosure maximizes the production of the needle coke having low CTE and low sulfur content in the delayed coker coke drum.
