BIOFUEL PRODUCTION LINES
- Biodiesel
- Bioethanol
Bio diesel is renewable and does not contribute to global warming due to its closed carbon cycle. Because the primary feedstock for bio diesel is a biologically-based oil or fat that can be grown season after season, bio diesel is renewable. And, since the carbon in the fuel was originally removed from the air by plants, there is no net increase in carbon dioxide levels.
Transesterification process:
Transesterificcation of neutral oils is carried out for the purpose of producing bio-diesel.
The process is fully contiuous and can also accept as part of the feed low grade materials as UFO (Used Frying Oils) or greases. The unit includes a glycerine treatment section that gives high quality crude glycerine.
Bioethanol fuel is mainly produced by the sugar fermentation process, although it can also be manufactured by the chemical process of reacting ethylene with steam.
Ethanol can be produced from biomass by the hydrolysis and sugar fermentation processes. Biomass wastes contain a complex mixture of carbohydrate polymers from the plant cell walls known as cellulose, hemi cellulose and lignin. In order to produce sugars from the biomass, the biomass is pre-treated with acids or enzymes in order to reduce the size of the feedstock and to open up the plant structure. The cellulose and the hemi cellulose portions are broken down (hydrolysed) by enzymes or dilute acids into sucrose sugar that is then fermented into ethanol. The lignin which is also present in the biomass is normally used as a fuel for the ethanol production plants boilers. There are three principle methods of extracting sugars from biomass. These are concentrated acid hydrolysis, dilute acid hydrolysis and enzymatic hydrolysis.
