(A) CONSERVATION OF ENERGY
(i) Steps Taken or Impact on Conservation of Energy:
ʀ Enhancement of bromine plant throughput and cement mill efficiency at Mithapur
ʀ Improve low grade heat recovery in soda ash plant and produced sweet water generation at Mithapur
ʀ Converted double effect evaporation to triple effect evaporation in (Make Up Water) MUW-4 Reconfiguration Phase III at
Mithapur Integrated Report
ʀ Replacement of pre-heater of ammonia still to reduce the heat load across the stack cooler at Mithapur
ʀ New capital projects being done with energy efficient motors, energy efficient lighting, high efficiency distribution
transformers and Intelligent Motor Control Centers at Mithapur
ʀ Replacement of super heater coils at Sulfuric Acid Plant (SAP2) and use of medium pressure steam from Sulfuric Acid Plant
(SAP1) in Turbo Generator (TG) motive section by modification of Pressure Reducing Device System (PRDS) loop resulted
in improvement of TG generation rating from 750 KwH to more than 1,100 KwH leading to increased power generation at
Haldia
ʀ Replacement of MV Lamps with LED lights at old and new warehouse leading to saving of energy at Haldia
ʀ Installation of capacitor bank at Haldia resulting in total savings of ` 34 lakhs during the year based on rebate of power
factor improvement
ʀ Reuse of the Evaporator Process condensate resulting in saving of 10% of ground water in terms of Kilolitres at Sriperumbudur
ʀ Saving of energy by installation of Variable Frequency Drive (VFDs) for Evaporator product circulation, sugar charging Statutory Reports
system and cooling tower fan by varying its speed based on temperature at Sriperumbudur
ʀ Synchronisation of DG set at Innovation Centre, Pune resulting in reduction of diesel consumption
ʀ Replacement of low efficiency High Pressure Sodium Vapour (HPSV) and Plug-in Light fittings with efficient LED light fittings
at Babrala
(ii) Steps taken by the Company for Utilising Alternate Sources of Energy:
ʀ Use of wind mill at Mithapur
ʀ Use of solar light at Mithapur
ʀ Solar power having 10 KwH are used for street lights at Innovation Centre, Pune
ʀ Replacement of conventional borewell system with solar borewell system at Sriperumbudur
