Abstract:

The disclosure provides for the integration of a CO-consuming process, such as a gas fermentation process, with a COto CO conversion system. The disclosure is capable of utilizing a CO-comprising gaseous substrate generated by an industrial process and provides for one or more removal modules to remove at least one constituent from a CO-comprising gaseous substrate prior to passage of the gaseous substrate to a COto CO conversion system. The disclosure may further comprise one or more pressure modules, one or more COconcentration modules, one or more Oseparation modules, and/or a water electrolysis module. Carbon conversion efficiency is increased by recycling COproduced by a CO-consuming process to the COto CO conversion process.

Abstract:

The disclosure provides methods to improve the economics of the gas fermentation process. A fermentation process is integrated with an industrial or syngas process and an reverse water gas shift process. An intermittent supply of reverse water gas shift process feedstock from the reverse water gas shift process is provided to the bioreactor for fermentation. The reverse water gas shift process feedstock may supplement or partially displace the C1 feedstock from the industrial or syngas process. Whether the reverse water gas shift process feedstock supplements or displaces the C1 feedstock may be based upon a function of the cost per unit of the C1 feedstock, the cost per unit of the reverse water gas shift process feedstock, and the value per unit of the fermentation product, or may depend upon the target gas ratio of the feedstock to the gas fermentation process.

Abstract:

An integrated process and system for the production of at least one gas fermentation product from a gaseous stream has been developed. The disclosure provides improved carbon utilization through both the recycle of a bioreactor tail gas via various different flow schemes and the employment of a COto CO conversion system such as a reverse water gas shift unit. Recycling of the bioreactor tail gas and employment of a COto CO conversion process provides for favourable H:CO molar ratios of the feed to the gas fermentation bioreactor(s) for enhanced production of fermentation products. Bypass embodiments provide for optimal sizing of the reverse water gas shift unit to minimize cost.
