  • Patent number: 10358662
    Abstract: The invention provides schemes for the integration of a fermentation process, with an electrolysis process, and a C1-generating industrial process. In particular, the invention provides process for utilizing electrolysis products, for example H2 and/or O2, to improve the process efficiency of at least one of the fermentation process or the C1-generating industrial process. More particularly, the invention provides a process whereby, H2 generated by electrolysis is used to improve the substrate efficiency for a fermentation process, and the O2 generated by the electrolysis process is used to improve the composition of the C1-containing tail gas generated by the C1-generating industrial process.

  • Publication number: 20190024133
    Abstract: Apparatuses and associated methods are described for the efficient evaluation of C1-containing substrates, and especially for such evaluation conducted locally, or on-site, at a prospective facility for implementation of a biological conversion process for desired end product using a C1 carbon source. The exact composition of a given, industrial C1-containing substrate, as well as the range in composition fluctuations, are generally difficult to reproduce at a remote facility (e.g., a laboratory or a pilot-scale or demonstration-scale process), as required for the accurate prediction/modeling of commercial performance to justify large capital expenditures for commercial scale-up.

  • Patent number: 9801687
    Abstract: The disclosure pertains to a perfusion system that is easy to set-up, use and monitor during a bypass procedure. In some embodiments, the disclosure pertains to a perfusion system in which at least some of the disposable components used with the perfusion system are configured to be able to communicate set-up and/or operational parameters to the perfusion system. In some embodiments, the disclosure pertains to a blood level sensor that can be used to monitor a blood level or volume within a blood reservoir. The blood level sensor may be utilized in an integrated perfusion system in which the disposable components are configured, as noted above, to communicate with the perfusion system. In some embodiments, the blood level sensor may be utilized with a perfusion system lacking communication with disposables.
