The Reynolds number NRe is maintained at not less than 4000 irrespective of the type of the reactor. The mixture of ester and glycerol is subjected to separation by known method for a period of not less than 4 hrs and the top layer ester is purified by conventional method for a period of not less than 8hrs. The process of separation as well as purification is repeated for not less than three times in succession to get biodiesel. Fig. 1. Lab scale experimental setup In lab scale experimental setup RBO was taken in the continuous stirred tank glass reactor 1 l with reflex condenser temperature control and agitation control setup. In another reactor NaOH 50 g was dissolved in methanol 300 ml . This solution was added slowly at the reactor maintained at 65-70 C for 150 min. Then the entire mixture kept in the separating funnel. The top layer biodiesel is taken for the removal of methanol in the ROTO vacuum distiller. Then the methyl ester washed of distilled water 1 l in the same reactor for 30 min. After washing top layer in the separating funnel has to be washed with saline water for two times. Finally clear biodiesel was kept in the oven for 4 h at 100 C. The ready to use biodiesel few samples shown in . 320 Biodiesel - Feedstocks and Processing Technologies Fig. 2. Ready to use biodiesel samples In the bench scale level Rice Bran Oil RBO experiments were carried out with standardized process conditions in high-pressure Parr Reactor . inbuilt sophisticated controlling systems of reactor 20 l . Rice Bran Oil Biodiesel RBOBD 150 l was produced. Fig. 3. Bench Scale lab Parr Reactor In each lot biodiesel sample has been analyzed for the conversion fuel properties and composition. Quality consistency .
