The srsintl process uses a multistep transesterification
response accompanied through neutralizing and washing steps. The multistep
transesterification reaction converts almost one hundred% of the triglycerides
in the oil or fats to biodiesel.
The methyl ester is then stripped to get rid of the water
and methanol. The very last step is to kick back and filter out the methyl
ester so as to take away impurities that shape at low temperatures. This
filtered methyl ester now meets the definition of transesterification
biodiesel and may be used as a gas, heating oil or other packages. The
glycerin byproduct separated from the methyl ester is in addition processed
with the aid of casting off methanol and a number of the water in order that it
that could easily be subtle in a glycerin refining plant.
