20090104676 | PROCESS TO SEQUENCE BIOREACTOR MODULES FOR SERIAL GAS FLOW AND UNIFORM GAS VELOCITY - This invention is a process for managing the gas flow through a plurality of bioconversion modules that provide a gas liquid interface. The conversion modules provide the gas liquid interface across an activated surface that converts at least some of the gas components into desired liquid products. Arrangement of the modules and control of gas flow in accordance with this invention enhances the utilization of the gas and the production of desired liquid products by adjusting the flow area to compensate for changes in the volume of the feed gas. Improved control of the gas velocity through the bioconversion modules eliminates problems of liquid condensation and flow maldistribution. The process may sequence the modules to mitigate time variation in microorganism activity and incorporate additional periodic process steps. | 04-23-2009 |
