Abstract

See full text

A system having a catalytic partial oxidation (CPO) reactor operable to produce a CPO reactor effluent characterized by a hydrogen to carbon monoxide (H2/CO) molar ratio and an M ratio (H2—CO2)/(CO+CO2); a steam methane reforming (SMR) reactor operable to produce an SMR reactor effluent characterized by a H2/CO molar ratio greater than that of the CPO reactor effluent, and an M ratio greater than that of the CPO reactor effluent. The system includes a flow line(s) configured to combine at least a portion of the CPO reactor effluent with at least a portion of the SMR reactor effluent to provide a combined syngas stream upstream or downstream of a heat exchanger operable to transfer heat from at least a portion of the CPO reactor effluent, at least a portion of the SMR reactor effluent, or the combined syngas stream to the first portion and/or the second portion of hydrocarbons.
