    摘要： The disclosure provides for the separation and combustion of at least one hydrocarbon, oxygenate, sulfur compound, and or nitrogen compound, from industrial gas or gasification derived syngas to generate steam. A gasification process and a gas fermentation process may be integrated using tail gas from the fermentation process for the flame to combust tar and other compounds from the syngas generated by a gasification process. Integration may be achieved by removing tar and other compounds from industrial gas or gasification derived syngas using an adsorbent and regenerating the adsorbent using tail gas from the gas fermentation process. Tail gas enriched with the desorbed tar and other compounds may be used to generate steam in a steam boiler and the steam may be used for a variety of purposes including power generation to power, for example, a compressor of the gas fermentation process.

    摘要： This disclosure is related to a process and apparatus for producing and recovering at least one fermentation product from a fermentation process using a C1-containing gas passed to a fermentation bioreactor, that produces a fermentation broth comprising at least one of a first product stream comprising ethanol and water or a second product stream comprising ethanol, acetone, and water or a third product stream comprising ethanol, acetone, isopropanol, and water. The product is recovered by using a shared product recovery system. Particularly, the shared product recovery system selectively recovers at least one enriched product stream selected from an enriched ethanol stream, an enriched acetone stream, an enriched isopropanol stream or combinations thereof. The shared product recovery system includes at least one of a vacuum distillation unit, a rectification unit, an acetone removal unit, a drying unit, an ethanol-acetone separation unit, an extractive distillation unit or combinations thereof.

    摘要： The disclosure provides for the integration of a gas fermentation process with a gasification process whereby tail gas from the gas fermentation process is recycled to a dryer of the gasification process. The tail gas from the gas fermentation process is utilized to generate heat which in turn is used to dry feedstock to the gasification process. The heat is typically used to heat a drying gas, such as air, which is then directly or indirectly contacted with the gasification feedstock to dry the gasification feedstock. Dried gasification feedstock provides improved yield and improved quality of syngas as compared to gasification feedstock that is not dried.

    摘要： The invention provides for the integration of a gas fermentation process with a gasification process whereby effluent downstream from the gas fermentation process is recycled to the gasification process. The invention is capable of recycling one or more effluents including biogas generated from a wastewater treatment process, tail-gas generated from the fermentation process, unused syngas generated by the gasification process, microbial biomass generated from the fermentation process, microbial biomass generated from a wastewater treatment process, crude ethanol from the product recovery process, fusel oil from the product recovery process, microbial biomass depleted water, wastewater generated from the fermentation process, and clarified water from a wastewater treatment process to a gasification process.
