Abstract
Microalgae has massive potential for the production of biofuels. Thermochemical conversion of microalgal oil is the potential route to produce diesel-range biofuels. This work provides the process design using Aspen Plus and economic analysis for transesterification and hydrodeoxygenation of microalgal oil to produce biodiesel and green diesel, respectively. In the present study, the microalgal oil derived from Nannochloropsis salina is considered as feedstock. Capital, operating expenses and the manufacturing cost of the biodiesel and green diesel have been estimated for various plant capacities ranging from 0.05 to 0.15 million metric ton microalgal oil per annum. The effect of plant capacity and different cost-contributing factors on the manufacturing cost of biodiesel and green diesel has also been studied. The manufacturing cost of diesel oil-equivalent biodiesel and green diesel was USD 4.425 and USD 4.294 per kg, respectively, for 0.125 million metric ton microalgal oil per annum.
