Is it possible to produde biodiesel using liquid – liquidfilm reactors?

If it is possible, is the productivity higher than theobtained in typical industrial process, where CSTR areused implementing three or more reaction-separationstages?

Why did we propose the use LLFC in biodiesel production?

Chemical and Environmental Engineering Department Bogota Campus

- To promote the contact of two phases (ester and alcohol– rich) without dispersing one phase into the other.

- To reduce separation time required in separators(decanters) downstream the reactor.

- To increase conversion and yield by simultaneousextraction of glycerol produced duringtransesterification reaction.

Why use LLFC in biodiesel production?

Chemical and Environmental Engineering Department Bogota Campus

- Because biodiesel production is mainly aheterogeneous reaction requiring dispersion of alcoholrich phase into ester rich-phase

- Because smaller the droplet size higher the residencetime in decanters and higher energy consumption

- Because chemical equilibria limit biodiesel yield. Thusseveral reaction stages are required to accomplishglycerol free and bonded specification 10

Conclusion

It is possible to produce biodiesel accomplishingspecifications defined in product standards using LLFRoperated in two different configurations: counter-currentand co-current using HFM implementing only one reactionstep, reducing separation time and, as a consequence,increasing process productivity. In co-current two reactionsteps are required.

The highest productivity was obtained for the LLFRoperated in co-current (with and without membranes).
