... will be compressed to 60 bar through the hydrogen compressor (a2), after being cleaned up further through deoxygenizing and drying. The purity of hydrogen production can reach an even higher value than 99.99%. The purge gas from the PSA subsystem will be fed to the power subsystem (combined cycle). The power...

In this paper, a technoeconomic analysis was carried out in order to evaluate performance and cost of biomass gasification systems integrated with two different types of plant, respectively, for hydrogen production and for power generation. An indirectly heated fluidized bed gasifier has been...
