Abstract
A process for steam cracking a hydrocarbon feedstock in a hydrocarbon cracking furnace is disclosed. The hydrocarbon feedstock is preheated in a preheating process module that is integrated with a coke handling system for supply of coke required for combustion. The coke is combusted in presence of oxygen containing gas to heat the heat carrier particles. The heat carrier particles contact the hydrocarbon feedstock to generate preheated hydrocarbon vapors. The flue gas generated by combustion of the coke is contacted with steam in an upper section of the heat source vessel to form dilution steam which mixes with the preheated hydrocarbon vapors to create a mixed stream The mixed stream is fed to the hydrocarbon cracking furnace for thermal cracking.
