PROCESS FOR THE GASIFICATION OF HEAVY OIL

摘要

A process whereby a high viscosity hydrocarbonaceous material is fed to a gasifier for conversion to synthesis gas. The feedstock, steam oxygen, and recycled gasification system water are all fed into the gasifier through a four stream feed injector (2), which includes a central cylindrical conduct (4) and second (60, third (8) and outer (10) cylindrical conducts radically spaced from each other. This setup provides a center passage (12), and a fir st (14), a second (16), and an outer (18) annular coaxial concentric annular passage. The upstream ends of each conduit ave a flanged inlet nozzle (20) f or the introduction of material. The feedstock in this design is sandwiched between two oxygen streams so as to provide better conversion for the exceptionally heavy feed. The further stream down the central layout (12) of the feed injector (2) provides the fllow path for the recycled water.
