Design of portable biodiesel plant from waste cooking oil

The design of portable biodiesel plant from waste cooking oil has been done simultaneously based on biodiesel standard of SNI 7182: 2012. Design of biodiesel production involves several processes including esterification, transesterification, decantation, vacuum evaporation, and ultra-filtration. Production of biodiesel has been simulated using several software packages. Based on the simulation conducted, the esterification process was able to convert 92.8% of FFA into FAME by using sulfuric acid as the catalyst with 10% w/w of FFA. Transesterification showed the biodiesel yield of 90% by using NaOH as the catalyst with 1% w/w of triglyceride. Evaporation on vacuum system was able to obtain biodiesel with methanol content less than 0.5% with lower energy consumption. Purification of biodiesel using ultra-filtration requires considerable energy but it was able to produce the purity rate of biodiesel up to 99.8% with relatively shorter time.
