This work focuses on modeling of Hydrothermal Liquefaction (HTL) of brown algae in the stoichiometric reactor model using Aspen Plus®. The type of compounds used in Aspen Model to represent HTL oil and associated aqueous phase must reasonably match key properties such as chemical group, density, heating value, GC-MS data. Compounds available in the Aspen database were chosen as replacements with the compounds present in the original experimental results based on their closest resemblance. Algae feed of 140,000 lb/hr was fed to the HTL reactor, 100 % conversion of the Algae and a balanced reactor was achieved yielding 76.5 % water soluble , 8.59 % of gas phase and 7.95% of non-soluble products. Furthermore, production of H2, by the gasification of the aqueous products followed by the Water Gas Shift Reaction and pressure swing adsorption shows the production of 65% of hydrogen and 35% of the off gas comprising of the CH4, C2H6, CO, CO2, N2 and a minute fraction of H2. |
