Abstract: A system and process for gas homogenization is disclosed. This has application in the areas of generation of gas and its conversion to electricity in downstream applications. The homogenization system minimizes variance in the gas characteristics (composition, flow, pressure, temperature), thereby rendering a steady stream of gas of consistent quality to the downstream machinery. This homogenization system can be adjusted to optimize the output gas stream for specific end-applications, or to optimize the output gas stream for different input feedstocks. This ensures that overall conversion efficiencies are maximized while keeping the process cost-effective. Such a uniform, steady output gas stream has a wide range of applications in the broad areas of generation of electricity (e.g. using internal combustion engines and combustion turbine engines), chemical synthesis (e.g.
