Production of ammonia, methanol, and synthesis products from one or more gasification products

A system comprising:

• a gasification unit configured to produce an unshifted syngas from biomass and oxygen;
• an electrolyzer coupled to the gasification unit and configured to receive water and to produce an oxygen product and a hydrogen product;
• an air stream connected to the gasification unit and configured to supply air to the gasification unit, wherein the air stream supplies at least a portion of oxygen to the gasification unit;
• a heat exchanger coupled to the gasification unit and configured to cool the unshifted syngas to produce a cooled syngas;
• a water gas shift unit coupled to the heat exchanger and configured to receive the cooled syngas and to produce a shifted syngas;
• a sulfur removal unit coupled to the water gas shift unit and configured to receive the shifted syngas and to produce a sulfur depleted syngas and a sulfur product;
• an absorption unit coupled to the sulfur removal unit and configured to receive the sulfur depleted syngas, remove carbon dioxide from the sulfur depleted syngas, and produce a CO2 depleted syngas and a CO2 product;
• a methanation unit coupled to the absorption unit and configured to receive the CO2 depleted syngas to produce a treated gasification product comprising hydrogen and nitrogen;
• and
• a combiner configured to receive the treated gasification product and the hydrogen product and to produce an ammonia synthesis feed stream having a mole ratio of hydrogen to nitrogen of about 3:1,
• wherein the oxygen product supplies at least a portion of the oxygen to the gasification unit, and
• wherein the electrolyzer is coupled to a renewable energy source.
