Producing SNG from crude oil and naphtha

An overall review is prevented of the technology available today for the gasification of the whole range of crude-oil-derived feedstocks, as well as the factors influencing the choice and combination of various processes. The four gasification processes reviewed include low temperature catalytic steam reforming of light naphtha; steam reforming plus gas recycle hydrogenation of heavy naphtha; partial oxidation plus gas recycle hydrogenation of middle distillates; and partial oxidation plus fluidized-bed hydrogenation of whole crudes. Typical economies for the four gasification schemes were developed. (MCW)
