Industrial scale Hydrogen production via hydrothermal liquefaction of brown algae, Saccharina Japonica based bio-refinery: An Experimental and simulation approach |
| 초록 |
This study focuses on hydrothermal liquefaction of Saccharina japonica as a feedstock to produce biocrude and subsequent hydrothermal gasification of aqueous product to produce hydrogen, which will be used as a feed for biocrude upgrading and other commercial purposes. Process is operated at a temperature of 300˚C with biomass to water ratio of 1:10 in sub-critical pressure condition. Experimental results were used to validate the process model designed on the Aspen plus simulator. A techno-economic model for the current process was developed to evaluate the cost-effective production of H2 gas. Pressure swing adsorption lead to a total hydrogen production of 2,400 kg/hr with a wet feed of 70,000 kg/hr. On site steam generation with total heat integration not only reduced the dependence on the external utilities but also produced 30MW of surplus power using methane as a fuel for combustion. The total capital investment for the plant was estimated to be $84.0MM with an operating cost of $80MM/year. |
