Hallo.. You might consider to add esterification reaction using Sulphuric Acid to reduce FFA Content. Or directly into transesterification, but it seems only acceptable if FFA is lower than 5% (but lower BD quality), it means you must use best quality of crude palm oil.
There is another option (in order to have best quality of BD): - Combining Biodiesel Plant with CPO refinery - Put side stream after deodoriser prior to cristalization (using steam with vacuum condition, so you will have less content of FFA). - And BD processing begin with Transesterification. This scheme will describe Keith comment (removing FFA and beta-caroten). FFA will be removed by deodorization, and beta caraten will be removed during bleaching and degumming. Still, I prefer to use waste edible oil (Palm Oil based) as BD raw material for Malaysia or Indonesia. I'm waiting further comment.. Thanks, Best Regard, A.

FFA levels range from 9-22%, not so easy. You might have to refine it first anyway. Also the beta-carotene content can interfere with the reaction in some processes.
