11,278 INTEGRATED PROCESS FOR THE PARTIAL OXIDATION- THERMAL CRACKING OF CRUDE OIL FEEDSTOCKS ABSTRACT OF THE INVENTION An integrated partial oxidation-thermal cracking process is disclosed for the more complete utilization of all chemical values in crude oil feedstocks employed in the concurrent production of synthesis gas and an olefin- rich stream comprising the steps of: burning, at a high temperature, streams of fuel And oxidant in the presence of superheated steam to form a reducing stream of hot combustion products; injecting a crude oil distillate fraction stream into said reducing stream of hot combus- tion products; passing the resulting injected stream to a reaction zone to effect thermal cracking of said crude oil distillate fraction steam and reaction products; thermally quenching said stream; removing pitch and frac- tionating to provide at least one stream of hydrocarbon oil and an olefin rich gas stream; separating carbon dioxide and any contained hydrogen sulfide from said olefin rich gas stream; separating streams of synthesis gas, methane, acetylene, ethylene, propylene and other cracking by-products from said olefin rich gas stream; and recycling fractions of said methane stream as fuel to said burning step.
