Abstract: Systems and methods relating to dynamic spargers for generating fine bubbles within reactors such as biological and chemical reactors. A sparger system is positioned within a reactor and comprises a support plate, multiple annular shrouds engaged with the support plate, and spargers positioned within the annular shrouds defining a gap between an interior surface of the annular shroud and an exterior surface of the corresponding sparger. Liquid flows through the defined gap between an interior surface of the annular shroud and an exterior surface of the sparger. Acceleration of the liquid through the gap shears bubbles at the exterior surface of the sparger creating bubbles or fine bubbles.

Abstract: The systems and methods disclosed herein provide for the efficient separation of gas from fluid comprising liquid. In particular, gas separator systems and methods for use in bioreactor systems and operations are disclosed herein providing an efficient means to remove gaseous waste products, unreacted gaseous substrates, and or inert gas from broth of the biological fermentation of carbon substrates using a microorganism biocatalyst.

Abstract: 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.

Abstract: The invention relates to the microbial fermentation of gaseous substrates to produce one or more products. The invention relates to the microbial fermentation of a gaseous substrate derived from the conversion of a biogas stream. The invention relates to the conversion of a biogas stream comprising methane to a gaseous substrate comprising CO or CO plus H2, and the production of one or more products from the microbial fermentation of said gaseous substrate.
