Patent number: 11753612Abstract: Processes, as well as associated systems and computer program (software) products, are disclosed for the biological conversion of CO into desired end products such as ethanol. The control methodologies used for these processes can advantageously result in a reduced time required for a batch operation or other initial operating period, prior to achieving a continuous operation, which may be demarcated either by the addition of fresh culture medium at a defined flow rate or by another process initiation target. The control methodologies may alternatively, or in combination, improve a process performance parameter, such as productivity of the desired end product or bacterial growth rate, during this batch operation or other initial operating period.Type: GrantFiled: March 8, 2017Date of Patent: September 12, 2023Assignee: LanzaTech NZ, Inc.Inventors: Christophe Collet, Guy William Waters, Jason Carl Bromley, Justin Yi Yang, Jarod Nathan Wilson

Publication number: 20230059296Abstract: What is described is an integrated steel mill and a bioreactor configured to produce useful products from the waste stream of the steel mill. A waste gas stack which is connected to the steel mill is connected to a heat exchanger to cool the waste gas from the steel mill. The cooled gas is pressurized using a pressurization apparatus connected to the heat exchanger. The pressurized gas is sent to an oxygen removal apparatus connected to the pressurization apparatus. An oxygen depleted waste stream from the oxygen removal apparatus is passed to a bioreactor (connected to the oxygen removal apparatus) where microorganisms ferment the waste stream to products. Optional apparatus such as scrubbers, valves, buffers, are also disclosed. The products of the fermentation in the bioreactor can be ethanol and or acetate.Type: ApplicationFiled: September 23, 2022Publication date: February 23, 2023Inventors: Sean Dennis Simpson, Christophe Collet, Michael Cockrem, Simon David Oakley, Michael Koepke
