EfficientSugar: A Perspective on Low Carbon
Opportunities in Sugar IndustryBackground
India has been known as the original home of sugar and
sugarcane. It is the second largest producer of
sugarcane, next to Brazil. This is a concept note put together
by us at EfficientCarbon to explain the potential for
conservation of energy and using renewable energy in the Sugar
Industry. With our experience in providing
energy efficiency services across industries and with our
linkages in Waste Heat Recovery and energy efficiency
products, we can guide you strategically in seizing low carbon
opportunities and help you in achieving the
maximum potential for energy efficiency in your unit.
Energy Consumption Pattern in Sugar Mills:
Energy consumption in sugar plants depends on various factors
such as its
Capacity Steam generation parameters Vintage and Equipment
used.
Apart from improving the end use efficiency in the plants, the
energy consumption in Indian sugar mills range
from 0.7 to 0.87 GJ/ tonne of cane against a world average of
0.5 to 0.6 GJ/ Tonne of cane crushed.

Co- generation:
Apart from energy efficiency patterns the other most promising
energy conservation measure for the sugarindustry is to set up
high-pressure cogeneration systems. This not only has the potential
of opening up additional
revenue streams for the sugar plants by way of sale of
electricity, it can effectively contribute in reducing the
ever widening gap between demand and supply of electricity in
various power deficit regions in the country. This
has also a significant reduction in carbon emissions.
Energy efficiency targets:
The estimated energy saving potential in the Indian sugar
industry is about 20%. This offers potential of about 650
MW of electrical energy. Energy efficiency in sugar industry
offers the following benefits:
In plants having cogeneration facility and where the state
utility is able to purchase additional powergenerated from sugar
plants, any improvement in energy efficiency levels of the plant
results in increased
export to the grid.
Specific Electrical Energy consumption 30 units/tonne of cane
with electric motors &
DC Drives
24 units / tonne of cane with diffusers
Specific Thermal Energy steam consumption 38% on cane

In plants, which do not have cogeneration facility, energy
efficiency directly results in reduced powerdemand from the state
utility. This results in higher profitability to the plant as well
as significant reduction in
GHG emission. These plants, however, are very few in number.
Waste heat recovery:
Nearly all types of engines, furnaces, boilers, and other
combustion devices release a substantial portion of the
energy they consume as heat. These wasted heat, can be harnessed
and put to productive use.
Renewable Energy uses:
The renewable energy generation technologies such as small
roof-top photovoltaic (PV) installations tomulti-MW wind farms
generated electricity can be feed into main supply of the sugar
plant.
Bagasse is the crushed remaining of sugarcane stalks left after
the extraction of juice. It can be used assource fuel for biomass
plant that to generate additional revenues.
Case study:
Installation of Thermo-compressor for use of Low Pressure
Steam
Before improvement After improvement
In a typical 4000 TCD sugar mill in Maharashtra,
the turbine exhaust steam at 20.40 kg/cm was
continuously vented out. The quantity of the steam
vented, amounted to about 6300 kg/h. There were
no process users in the sugar mill or the distillery,
which could utilize this exhaust steam of 0.40 kg/cm.
The distillery required 10 TPH of steam at 1.5 kg/cm.
A separate boiler was meeting the steam
requirements of the distillery. The sugar mill boiler
met any additional requirement of steam. In boththe cases, steam
was generated 2 2at 8 kg/cm and
reduced to 1.5 kg/cm through a pressure-reducing
valve.
A thermo-compressor system was installed, for
reusing the turbine exhaust steam, in the distillery.
The resultant MP steam saved in the distillery was
passed through the power generating turbines, for
generation of additional power.
The resultant 1.5 kg/cm steam obtained by thermo-
compression of exhaust steam was directly used in
the distillery. This reduced the passing of high/
medium-pressure steam through the pressure-reducing valve.
