Methanol Production via Dry Reforming and Methanol Synthesis in a Vessel

A method of producing methanol, comprising:

• converting methane and carbon dioxide via a dry reforming catalyst in a dry reforming section in a reactor vessel into syngas comprising hydrogen (H2) and carbon monoxide, wherein the converting comprises dry reforming;
• flowing the syngas from the dry reforming section through a heat exchange section in the reactor vessel to cool the syngas with a cooling medium in the heat exchange section;
• injecting H2 into the syngas in the reactor vessel in response to specifying to increase a molar ratio of H2 to carbon monoxide of the syngas in the reactor vessel, wherein the H2 injected is injected into a discharge portion of the dry reforming section or into the heat exchange section;
• flowing the syngas as cooled from the heat exchange section to a methanol synthesis section in the reactor vessel, wherein the dry reforming section and the methanol synthesis section are enclosed within the reactor vessel in an interior of the reactor vessel;
• synthesizing methanol from the syngas via a methanol synthesis catalyst in the methanol synthesis section;
• discharging effluent comprising the methanol from the reactor vessel;
• processing the effluent to remove hydrogen, carbon monoxide, and carbon dioxide from the effluent to give the methanol as product;
• and
• providing carbon dioxide removed from the effluent to the dry reforming section.

A methanol production system comprising:

• a reactor vessel comprising:
• a feed inlet to receive a feed comprising methane and carbon dioxide;
• a dry reforming section comprising a dry reforming catalyst in the reactor vessel to convert the methane and the carbon dioxide into syngas comprising hydrogen and carbon monoxide;
• a heat exchange section comprising a heat exchanger in the reactor vessel to receive the syngas from the dry reforming section and cool the syngas with a cooling medium;
• and
• a methanol synthesis section comprising a methanol synthesis catalyst in the reactor vessel to synthesize methanol from the syngas and discharge an effluent comprising the methanol from the reactor vessel.
