Thermodynamic Analysis of Waste Vegetable Oil Conversion to Biodiesel with Solar Energy

Exergy and energy analyses of two biodiesel production processes that integrate solar as the main source were developed to determine process with higher efficiency from an exergy approach. The simulated in ASPEN PLUS®, supply was studied TRNSYS®, using EXCEL® simultaneously for exergetic analysis. thermal collection system can 81% required by alkali Flash separation equipment. For supercritical process, 74.5% preheating stages. is higher; nevertheless, alkaline than one. Solar systems contribute 85% 93% destroyed global both cases. has highest advantages when energy, compared a conditions presents greater irreversibilities requires more infrastructure collect resource. However, foremost offers alternative fossil fuels, it provides environmental benefit concurrently use biodiesel.
