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.

A method for removing chloride impurities from a heavy hydrocarbon stream is disclosed. The heavy hydrocarbon stream is contacted with a stripping medium at a temperature ranging between 100-450&#xb0; C. and at a pressure ranging between 0.1-2 bar with ratio of the heavy hydrocarbon stream to the stripping medium ranging between 1-30; wherein the temperature is maintained below the initial boiling point of the hydrocarbon stream.

The present invention provides a process for regeneration of the sulfur capturing spent adsorbents after sulfur capturing using a hydrolyzing agent under adiabatic conditions. In accordance with the process of the present invention hydrolyzing agent is introduced to the spent adsorbent in a controlled manner such that the exothermic heat generated within the adsorbent bed does not rise above the predetermined temperature limit.
