Bharat Aluminium Company (BALCO) has made significant contributions as the1st PSU in India’s Aluminium sector Incorporated in 1965, BALCO is India’s firstintegrated Aluminium business.

One of the first disinvestments of the Government of India. It now a part ofVedanta Limited, with 51% stake held by Vedanta Limited and 49% held byGovernment.

Balco is based in Chhattisgarh State having Captive Bauxite mines in Mainpatand Kawardha, Captive coal mines in Chotia, 2010 MW power generationcapacity and 5.7 LTPA Aluminium Smelting capacity at Korba Complex.

Balco produces Wire Rods, Ingots, Alloy Rods, Alloy Ingots and Rolled Products.Balco is also selling Power to State Utilities & own sister concerns.

Balco has been India’s first to have - Captive Power Plant, to venture into +300kA Prebake pots, to produce Alloy Rods for conductors used in powertransmission industry, to roll material for Aerospace Industry, online riserreplacement, busbar insulation in Pot Room, single beam implementation andholds patent for aluminium cell fuse technology.

Innovation-Project 1

Project Title:

Utilization of LP compressed air for FTP Line-2 operation to reduce Auxiliary power consumption.

Project Details:

Modification done in HP(high pressure) pipeline and LP(low pressure) pipeline to run FTP operation by LP compressed air instead of HP compressed air which results into reduction in power consumption by 12 MWH/day.

Study of Pressure and flow (by internally and third party also) to run FTP operation by LP compressed air and its impact on FTP operation as well as power consumption.

Pressure setting of pressure regulating valves(PRVs) changed. Before 6 bar pressure from HP Line used for operation after modification it is changed to 4 bar.

Implementation

Action Plan

In-house modification with our own resources. MOC Making and approval for implementation in shop floor Fabrication of U bend to interconnect LP and HP pipeline. Arrangement of 350 mm butterfly valve Shutdown of FTP and alumina handling to interconnect pipeline Fitting of 350 mm valve in both the pipeline HP and LP line separately. Requirement of pressure for FTP operation is approx. 2.5 bar so change setting

of pressure regulating valves as per operation by LP compressed air.(from 6 bar to 4 bar)

Data calculation for Power consumption of compressor house. By these calculation and implementation we found that we can save approx.

12 MWH/day by utilizing low power consuming compressor for FTP operation instead of high power consuming compressor as used previously.

Graphitized Cathode with copper insert collector bar design

The Aluminum production is an energy intensive process. To be more costefficient, the process needs to be more energy efficient. Energy efficiencydepends mainly on the technology used and relining materials being used.In a electrolytic cell, energy consumption can be reduced by reduction ofvoltage drop & Increasing the pot life.

To collect the historical data, pots were chosen having same cell design,located within same pot line and similar age. Cathode voltage drop (CVD)and wear rate of cathode were taken as performance indicator.

1. In electrolysis process, generates horizontal & vertical component of electric current between anode & cathode. High Horizontalcomponent indicates high noise, Voltage swing. High vertical component indicates pot stability means high CE & high life. This verticalcomponent can be increased and horizontal component can be reduced by inserting the copper plate in Collector bar .Through this,collector bar resistivity will also reduce (improving the cell magneto-hydrodynamic (MHD) state).

2. Copper is high thermal conductive material so that heat dissipation will be more in copper insert collector bar so that new lining designkeeps the heat in the pot, i.e. reduces thermal losses.

Data Analysis, Countermeasures & validation

Accuracy and repeatability of measurements is important as data is input for calculations. The higher thermal conductivity of Copper insert collector bar cathode compared to normal collector bar cathode blocks required added insulation within the cell lining to maintain the same thermal balance without increasing the energy required to operate the pot.

This operating window is defined by the thermal limits (bath freezing and melting of the ledge) and the stability of the pot. Further constraints about minimum metal output or maximum specific energy consumption can be included to understand the regions where the operation of the pot is possible,

Cathode Voltage Drop and wear rate has been substantially lowered than reference graphitized cells and leading to reduction in Specific Energy Consumption and satisfying project target.

Previously the EMS (Electromagnetic Stirrer) was working on an Offline and stand-alone mode and there was no provision for capturing the Running hours and also no automated control over ON/OFF and totally dependent on Operator’s feedback which led to excess power consumption.(Minimum 1000 kWh/day)

Electromagnetic Stirrer is being used in order to improve the temperature distribution inside the furnace and chemical homogenization of alloying elements like Silicon, Titanium , Magnesium, Strontium for better quality of Primary Foundry Alloy (PFA) material for our prime customers

BEFORE - The running hours of EMS unit was noted manually and also it was running 24x7 as there was no automated control system over Start/Stop of the EMS and this in-turn led to excess Power Consumption.

AFTER - In order to overcome the above shortcomings we have integrated the Furnace and EMS unit and captured the Start and End bit of the EMS and calculated the time . We have installed a large LED at shop floor, a provision to display the Current status of EMS to the operator through Green and Red indicators . We have shown the critical parameters of BEFESA , Furnace, EMS so that anyone in shop floor can get a clear view of current status. Also programming in PLC has been made in such a way whenever furnace is in tilt position EMS stops immediately without any manual intervention through reed switch relay.

Project Effect

All the Stand-alone units like EMS, Furnace and Alloy ICM have now been integrated via common network platform in Historian server through critical tag values and using MES this automation has been achieved. Also programming has been made in such a way whenever furnace is in tilt position EMS stops immediately without any manual intervention through reed switch relay. One LED has been provided at Shop floor for the same.

Power saving of 300 MWH/Year which will give net saving of 0.23 $/MT/Year and fulfilled the Customer requirements of Hero MotoCorp ,Enkei, Kosei Minda for best practices in shop floor

Through Implementation of Automation of EMS following Cost benefits will be achieved:

As per OEM in Full capacity 6 Cast per day is proposed, Power requirement before project was 6*950=5,700 kWh . After completion of the project the Power consumption is expected to reduced by 6*780=4,700 kWh

Power saving= 1,000 kWh/dayApprox.it saves 25,000 kWh per month

Cost of Power=2.3 Rs./Watt

Therefore Total Cost Saving = 2.3*25*1000= Rs.57,500 per Month

Total Annual Savings = 57,500*12= 6.9 Lacs/Year

Net Savings = 0.23 $/T/Year
