The
Distillary st Vaidyanath SSK, Pangri has ushered in the era
of Smart Distillary in the world. The plant which has been
inspired by Praj, will run on molasses as well as Secondary
Cane Juice. The Smart aspect of the distillary lies in its
ability to switch over from one raw material to another at
the flick of the knob to produce a wide spectrum of Rectified
Spirit (RS), Export Quality Rectified Spirit (EQRS), Extra
Neutral Alchohol (ENA) and Fuel Ethanol. The concept of blending
two or more feed stock for production of alchohol streams
from the fact that Distillaries would like to operate round
the year instead of 6 months/year, as in case of India. At
the same time the intention is to minimise the effluent levels
so as to use the available facilities. It is also desirable
not to depend on external/bought out sources of raw materials.
Also the return on investments is far more attractive as compared
to distillaries operating during half the year. Vaidyanath
SSK had spelt out this requirment and Praj designed a plant,
which would run on captive foodstock. The plant runs on: HIFERM
GR Technology (30,000 litres per day) ECOMOL Molecular Sieve
Plant for production of 45,000 litres per day Fel Ethanol.
Plant highlights are:
- Use
of secondary juice as well as cane molasses feedstock
- Ease
of switching from one raw material to another
- Multiple
grades of alcohol from the same plant: RS, EQRS, ENA
- Reduction
in process water consumption
- Energy
saving due to multipressure system
- consistency
in product quality
- Fully
automated multipressure distillation & fuel ethanol
plant
- Common
effluent treatment plant
- Reduction
in effluent volume
Secondary
juice is a stream for alcohol production. Because it has a
very low concentration of baggable sugar in it & lot of
non-sugar solids in it, it does not produce very high quality
of sugar. Secondary juice being a dilute stream of sugar,
also consumes high quantity of steam for its evaporation.
However the non sugar solids in Secondary juice do not cause
any problem for fermentation and thus can be very easily taken
for fermentation. On the contrary it has a very high Fermentable:
Non Fermentable ratio, which is good for fermentation as compared
to that of molasses.
