Abstract: A fermentation unit and a method of carrying out fermentation are described. The fermentation unit can be transported from one facility to another to carry out a fermentation process. The fermentation unit and method allow for the fermentation of a C1-containing substrate from a source at a particular facility to produce products such as alcohols and acids. Examples of the source of the C1-containing substrate include without limitation steel manufacturing processes, coal and biomass gasification processes, coke manufacturing processes, etc. The fermentation unit can be housed within a container having a volume of less than about 6 m3.

Abstract: 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.
