Process simulation of biodiesel production from vegetable oil deodorization distillate using hydrotalcite-hydroxyapatite as catalyst

In There are few simulation studies in the literature focusing on production of biodiesel from vegetable oil deodorization distillate (VODD), a waste originating processing stage, using hydrotalcite-hydroxyapatite as heterogeneous catalyst. this study, process was performed open interface software DWSIM® Version 6.3. The motivation relied positive performance catalyst during experimental studies. So, simulator design, lipid raw material, ethanol, and were fed together CSTR-01 conversion reactor. thermodynamic fluid package used for Non-Random Two-Liquid (NRTL) activity coefficient model. flowchart consisted reaction step (oil transesterification), separation steps ethyl esters produced, excess ethanol purification biodiesel. As result, different scenarios simulated, commercial soybean comparative form, types catalysts molar ratios alcohol VODD. Among main differences between simulated cases, it demonstrated that (1:45) caused greater quantity VODD consumption, consequently formation (biodiesel), resulting higher conversions (> 95%). addition, results obtained confirmed adequacy potential material to produce biodiesel, is relatively cheaper than edible oils contributes use waste. Thus, confirming chemical able form fatty acids even residual material.
