2. Awards and Accolades
i. The steps taken or impact on conservation of energy:
3. Conservation of energy
• Power factor improved and maintained near to unity.
• High wattage conventional lights were replaced by low power consuming LED lights with expected annual power saving to the tune of more than Rs. 48 lakhs.
• 14 nos. 22.5 KW motors were replaced with EEF motors of 18 KW at MCP.
• Premium class IE-3 Energy Efficiency Motors were introduced in place of 30 to 40 yrs old conventional Motors in Flash Smelter & Refinery in phased manner at ICC.
• Separate Energy Meters have been installed for crushers, rod mills, ball mills etc and close monitoring is being done to reduce idling of these machineries at KCC.
• At KCC, Input size for rod mills have been improved by reducing the settings of all the crushers and replacing 50% of the screen panels of 30 mesh size with screen panels of 30 mesh size. Consequently, efficiency has improved and energy consumption has reduced by 0.8 KW/ Tonne of milling.
• At ICC, Furnace oil fired package boiler and DG sets have been installed as alternate to coal based captive power plant. In addition to the boiler and DG set electric driven motor blowers installed in place of steam driven blowers for converting operation of flash smelter and converter tilting mechanism has been modified with electro-pneumatic system (Dual drive system).
ii. The steps taken by the company for utilizing alternate sources of energy:
• 5.75 KWp solar power has been added to the existing 35.25 KWp Roof Top solar power plant at Malanjkhand Copper Project.
• M/s REIL has been entrusted to carry out the rooftop solar power feasibility study in all five units and Corporate Office.
iii. The capital investment on energy conservation equipment: Rs. 26 crores
i. The efforts made towards technology absorption:
4. Technology absorption
• Efficient furnace oil fired package boiler has been commissioned replacing old coal fired boiler at ICC.
• Modern electric driven blowers commissioned in place of steam driven blowers for converting operation of flash smelter,ICC.
• Converter tilting mechanism has been modified with electro-pneumatic system (Dual drive system) at ICC.
• New coiler with conveyor system is being installed at TCP to improve the product packaging.
• Modification in cleaner flotation circuit to arrest spillover of material with addition of sodium silicate for improving the quality of final concentrate (product) at MCP.
ii. The benefits derived like product improvement, cost reduction, product development or import substitution:
• Efforts made towards technology absorption has resulted reduction in energy consumption, improved environmental protection and ensured safety of operations.
iii. In case of imported technology (imported during the last three years reckoned from the beginning of the financial year) :
(a) The details of technology imported-
1. Modern electric driven blowers’ technology imported from China at ICC to fulfill the requirement of converting operations.
2. The EMEW technology imported from Canada. The technology will help HCL to recover LME-A grade cathode from lower concentration of copper in spent electrolyte which is otherwise not possible by conventional means. Besides this, the technology will also help HCL to recover nickel from the spent electrolyte at ICC refinery
3. Another technology of Acid purification Unit (APU) was imported from Canada. The technology will allow HCL to separate and recycle back the major part of the acid from the spent electrolyte at ICC Refinery. This eco-friendly technology will allow reduction of liquid effluent and help HCL to recover nickel in the downstream process.
