It's
no secret that the world today is yearning for renewable energy sources that
can combat issues like harmful emissions, depleting fossil resources and
spiraling fuel prices. Ethanol
Industry is being viewed as a viable alternative which is expected to
play a critical role in meeting the growing demand for renewable energies and
cleaner fuels.
While
initiatives are being taken at different levels, the introduction of one of the
latest technologies Enfinity is the
breakthrough that is likely to take the bio-refinery sector by storm. Enfinity is the brainchild of Praj Industries
which is one of the most trusted names in the bioenergy spectrum, known for
delivering the best ethanol plant solutions.
Enfinity Ethanol Technology
 |
| Ethanol production process |
It is the 2G or
second-generation cellulosic ethanol technology that utilizes the available
renewable sources for bio-fuel solutions that successfully meet the
environmental and energy challenges. The smart Bio-Refinery system based on
Enfinity technology is equipped with multi-feed capability and improved
biological processing ability.
Unlike the first-generation ethanol
production process that depends on food crops, typically corn and sugar
cane as raw material, Enfinity uses agricultural wastes like rice husk, palm
residue, wheat stalks, corn cobs, and other ligno cellulosic biomass. It
utilizes different kinds of enzymes to break these organic wastes into glucose or carbon sugars from
which ethanol is extracted. The complete production process encompasses
enzymatic hydrolysis, co-fermentation, and distillation and is a thermally
integrated system that facilitates optimum energy consumption.
Features of 2G Ethanol Technology

Higher yield
●
Lower reaction time
●
Higher tolerance to solids
Other HIghlights of the Technology
1.
Optimum Capacity – 1 million liter
per annum
2.
Capability to process multiple feedstock - corn cobs & stover,
rice & wheat straw, cane trash, cane bagasse, cotton stalk, empty fruit
bunches (EFB)
3.
A holistic approach with an end to end offering; from feedstock
processing till end product and wastewater
treatment.
4.
Process integration facilitating optimization of energy & water
consumption.
5.
Efficient wastewater management with Zero
Liquid Discharge system
6.
Operating cost at par with global competition.
7. The technology is
designed to produce Bio-ethanol, Bio-gas with provision for the set-up of
Bio-CNG unit
Another Milestone Achieved
Praj
Industries has spread its wings far and wide and is a name to reckon with in the
global biofuel technology solutions. Its 2G ethanol technology will now be used
for USA’s bagasse-based biorefinery. ‘Enfinity’ will be deployed to produce ethanol and other
co-products using sugarcane bagasse in the bagasse-based bio-refinery. The
bio-refinery will be jointly promoted by Florida based Omega Energy USA, a
developer of renewable energy projects, while Louisiana based Lasuca Sugar, a
producer of cane sugar, will supply bagasse feedstock. With Enfinity gaining
global recognition and acceptance from developed markets like that of USA, it
reinforces the position of Praj industries as a global leader in the advanced
bio-economy.
