<p>The disclosure relates to a process for converting a feed gas stream, comprising at least one of CO or a mixture of CO2 and H2, to a liquid product by contact with a fermentation liquid, wherein the liquid product reduces the surface tension of the fermentation liquid, wherein the process uses the gas stream at a relatively low pressure to eliminate the use of a compressor. The process uses a liquid stream as the primary energy input to a gas injector that intensely mixes gas and the liquid with reduced compression costs while the presence of the liquid product maintains the gas-liquid dispersion as it flows downward to build a static pressure head. The process lowers the required gas pressure by adjusting the elevation of the gas injector such that a conduit receives the gas-liquid dispersion from the outlet of the injector and confines it as it travels downward to enter the bottom of a column of liquid. The liquid product provides a surface acting agent that prolongs the creation and duration of microbubbles in the gas-liquid dispersion.</p> |
