Synthesis Gas from Partial Oxidation of Fuel Oil

Abstract

The residual oil feedstock and process oxygen are preheated to 2450C and pressurized to about 70 bar. Along with recycle soot, and steam diluent, the mixture is passed to the parallel partial oxidation reactors. Reactor residence time is 3.8 seconds at 59 bar and 1430'C. Hot reactor effluent gas is rapidly quenched to about l800C. Crude synthesis gas passes to the quench/separator and crude gas scrubber system to remove residual soot and further cooling to 60-650C. It then passes to the acid gas removal area and sulphur recovery for further upgrading.
