fuels are near extinct. There is an immediate need of reliable and sustainable
alternate energy source as the world is facing the dangerous energy crisis.
Biofuel is most promising and eco friendly alternative energy source. Biodiesel extraction from various
vegetable non edible seeds and animal fats is gaining sufficient momentum in
India. Sustainability of biodiesel plants and current biodiesel
technologies are the issues of concern. Biodiesel plants in India require both monitoring and
intelligence of human operators in several aspects and stages. A
sustainable biodiesel production must utilize energy-efficient non-conventional
process stages, online calculation of Free Fatty Acid (FFA) in raw seed oil,
continuous online monitoring of extraction stages and faster/efficient
esterification process. Challenges
and difficulties in transesterification process, and various automation
issues for a biodiesel plant are presented here. In this paper automation method for the complete
transesterification process from crude oil handling stage to the biodiesel
production is proposed and the practical implementation is initiated.
