A system having a catalytic partial oxidation (CPO) reactor to produce, from a CPO reactant mixture, a CPO reactor effluent characterized by a hydrogen to carbon monoxide (H2/CO) molar ratio and a M ratio defined as (H2−CO2)/(CO+C=2). The system includes a water-gas shift (WGS) reactor configured to produce a hydrogen enriched reactor effluent from at least a portion of the CPO reactor effluent, wherein the hydrogen enriched reactor effluent is characterized by a H2/CO molar ratio that is greater than the H2/CO molar ratio of the CPO reactor effluent. The system includes a CO2 separator operable to remove a portion of the CO2 from the hydrogen enriched reactor effluent to yield the syngas, wherein the syngas is characterized by a M ratio that is greater than the M ratio of the CPO reactor effluent and of the hydrogen enriched reactor effluent. Processes for producing the syngas and producing methanol therefrom are also provided.

Production of synthesis gas and of methanol

A system having a catalytic partial oxidation (CPO) reactor operable to produce a CPO reactor effluent characterized by a hydrogen to carbon monoxide (H/CO) molar ratio and an M ratio (H&#x2014;CO)/(CO+CO); a steam methane reforming (SMR) reactor operable to produce an SMR reactor effluent characterized by a H/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.
