Abstract

Optimization of the operation of the Direct-contact Counter-current Falling Film Evaporator for the crude Jatropha curcas L. oil refining was done in this study by varying the vacuum pressure and steam flow rate. The evaporator column was run under 5 inHgand 10inHg pressure and with half open valveand fully open valve saturated steam supply at 110ºC and 15psi. The degummed and stripped Jatropha curcas oil were analyzed for FFA content using titrimetric method and thin layer chromatography (TLC) method. The column was able to reduce the FFA content in the oil to about 38.5%on average based on titrimetric method and 57.2% on average based on TLC method at 10inHg and fully open valve configuration. The effect of varying the steam flowrate was evident on the results from titrimetric method whole both steam flow rate and pressure affects the result from TLC. The highest reduction of FFA with 46.3% for titration and 86.9% for TLC was at fully open valve configuration for steam flowrate and 10inHg for pressure. Results showed that at vacuum pressure condition higher FFA content was reduced.
