2.2.7. Biogas plant and methane upgrading
The C5 fraction from the organosolv process and stillage from the ethanol recovery contain valuable by-products such as xylose, acetic acid and furans. One option for utilization is to
develop a complex by-product recovery and separation system. However, the necessary processes have a high energy demand and are still in development, so that at present a profitable operation of this option is probably not realistic (Michels, 2014). Alternatively, in this study, the utilization in a biogas plant and upgrading to biomethane is considered – simulation flowsheet, see Fig. 2d.
