Definitions

  • a system and process is provided for generating power from a syngas fermentation process. More specifically, a process is provided for generating high pressure steam from gasification and fermentation of syngas.
  • Microorganisms can produce ethanol and other compounds from carbon monoxide (CO) through fermentation of gaseous substrates.
  • the CO is often provided to the fermentation as part of a gaseous substrate in the form of a syngas.
  • Gasification of carbonaceous materials to produce producer gas or synthesis gas or syngas that includes carbon monoxide and hydrogen is well known in the art.
  • such a gasification process involves a partial oxidation or starved-air oxidation of carbonaceous material in which a sub-stoichiometric amount of oxygen is supplied to the gasification process to promote production of carbon monoxide.
  • Syngas produced by gasification processes described in the art can be hot and needs cooling prior to downstream processing and subsequent fermentation.
  • Hot syngas comprising carbon monoxide generated in a gasification apparatus, is cooled in a heat exchanger or waste heat boiler downstream of the gasification apparatus, see for example U.S. Pat. No. 6,435,139; U.S. Pat. No. 7,587,995 and U.S. Pat. No. 7,552,701. Recovery and use of this heat content of hot syngas can be very important for process economics.
  • a process and system are provided that effectively generate high pressure steam from a syngas fermentation process.
  • the process includes contacting hot syngas having a temperature above about 1400° F. with cooled syngas to produce a pre-cooled syngas having a temperature of 1400° F. or less at an inlet of a waste heat boiler.
  • a waste heat boiler receives the pre-cooled syngas and is effective for producing waste heat boiler high pressure steam and a cooled syngas.
  • a system for generating high pressure steam from a syngas fermentation process.
  • the system includes a waste heat boiler positioned to receive syngas having a temperature of 1400° F. or less.
  • the waste heat boiler effective for producing waste heat boiler high pressure steam and cooled syngas.
  • a vent gas burner receives lean syngas from a fermentor and the vent gas burner is effective for producing hot vent gas burner gas.
  • a vent gas boiler superheater receives the hot vent gas burner gas and the vent gas boiler superheater is effective for producing vent gas boiler high pressure steam.
  • a steam mixer receives and mixes the waste heat boiler high pressure steam and the vent gas boiler high pressure steam to produce a combined high pressure steam.
  • a process for generating high pressure steam from a syngas fermentation process.
  • the process includes combusting carbonaceous materials in a gasifier to form a hot syngas having a temperature above about 1400° F. and pre-cooling the syngas to produce a pre-cooled syngas having an average temperature of 1400° F. or less at an inlet of a waste heat boiler.
  • a waste heat boiler receives the pre-cooled syngas and is effective for producing waste heat boiler high pressure steam and a cooled syngas.
  • a fermentor receives cooled syngas.
  • a vent gas burner receives lean syngas from an outlet of the fermentor and the vent gas burner is effective for producing hot vent gas boiler gas.
  • a vent gas boiler superheater receives the hot vent gas burner gas and waste heat boiler high pressure steam and produces a combined high pressure steam.
