A FERMENTATION METHOD

WIPO Patent Application WO/2012/087949

A3

This invention relates to the integration of an ammonia production process with a fermentation process to produce products such as alcohols and/or acids in addition to ammonia. In a specific embodiment, a natural gas stream comprising methane is passed to a reforming zone to produce a substrate comprising CO and H2. The substrate is next passed to a bioreactor containing a culture of one or more microorganisms and fermenting the culture to produce one or more fermentation products comprising alcohols and/or acids and an exhaust stream comprising CO2, and H2. The exhaust stream can then be passed to a separation zone to remove at least a portion of the CO2 and produce a purified exhaust stream comprising H2 which is then passed to an ammonia production zone and is used to produce ammonia.
