Process simulation and economical evaluation of enzymatic biodiesel production plant

Environmentally-Benign Dimethyl Carbonate-Mediated Production of Chemicals and Biofuels from Renewable Bio-Oil

“…For example, when lipase price are 1500, 1000, 750, 200, and 100 $/kg, respectively, the immobilized lipase needs to be reused for more than 320, 210, 160, 50, and 20 batch reactions without significant loss of catalytic activity [61]. Sotoft et al [62] also investigated TEA of enzymatic biodiesel production. The estimated biodiesel price was 0.73-1.79 €/kg based on enzyme price of 762.71 €/kg and 0.05-0.75 €/kg with enzyme price of 7.63 €/kg.…”

Production of Biodiesel from Microalgae

“…99-125) immobilized on macroporous resins at a concentration of 30% (g/g lipid, 12000 U/g lipid) at 38˚C during 12h (Li et al, 2007;Xiong et al, 2008). However, enzymatic biodiesel production is often seen expensive due to the cost of the catalyst from 236 to 836 $US/ton biodiesel (Sotoft et al, 2010). In comparison, the price of acid catalysts like H 2 SO 4 (98%, w/w) is as low as 100 $US/ton H 2 SO 4 (Tao & Aden, 2009) for a price of catalyst for biodiesel production from 1.4 to 5.3 $US/ton biodiesel (1 and 5% (w/w) catalyst, respectively) (Lotero et al, 2005).…”

Biodiesel Fuel Production by Enzymatic Transesterification of Oils: Recent Trends, Challenges and Future Perspectives

“…A very interesting and important study was conducted by Sotoft et al They carried out the process simulation and economical evaluation of an enzymatic biodiesel production plant (Sotoft et al, 2010). Since there is, to date, only one plant in the world that uses enzymatic transesterification of biodiesel these kinds of studies are very important to make a correct evaluation of the industrial potential of a particular process.…”
