Case Study - Upgradation of an
existing Evaporator Station
Our client has a Beet
Sugar Factory processing 4,000 tons of beet per day
for 110 days per year, with Evaporator station providing the following
performance based on Diffuser Juice having Brix of
13º and Draft juice at 115% Beet.
Brix of thick juice - 40º
Steam Consumption - 110 t/h
He set us the task of upgrading
his station to provide the following performance;
Brix of Thick Juice - 65 - 70º
Steam Consumption - Less
than 35% on beet.
After implementing our
proposed system changes, the following performance was achieved from the
upgraded Evaporator Station with same feed conditions i.e,
Diffuser Juice Brix of 13º and Draft juice at 115%
Beet.
Brix of Thick Juice - 65 - 68º
Steam Consumption - 65 – 70 t/h
Capacity - 4,500 TBD (see note below)
Note – the
upgraded Evaporator Station was designed to allow future expansion of the plant
to 6,000 TBD without any additional investment.
Net savings from the upgradation
project
On account of Fuel Oil - 64 tons per day
Cost of Fuel Oil for
Boilers - 148 USD / ton
Number of operational
days - 110
Total saving on account of Fuel Oil: 64 x 110 = 7,040 tons
x 148 USD / ton = 1,041,920 USD per
campaign.
Our client was also able to eliminate his Water Treatment
Plant due to the additional amount of Condensate Water exiting from the
upgraded Evaporator Station. The savings on account of this – 1,900
USD / day x 110 days = 209,000 USD per year.
Total saving in one
campaign = 1,250,920 USD
Return on investment - 1 year
