Waste Heat Recovery Plant – acquisition of green technology!
In any Industrial process heat is wasted as a result. If not used efficiently, waste heat is released into the atmosphere. A Waste heat recovery (WHR) plant utilizes residual heat, consuming no fuel, and lowering dust emissions and temperature of discharged flue gas thus having a positive impact on the environment.
Lucky Cement has five Waste Heat Recovery Plants: Three in Pezu and two in Karachi. The WHR plant at Pezu are on line AB and CD with a capacity of 10MW and 15MW respectively. The third is used for Power Generation with a capacity of 6MW. Karachi has a WHR unit on line EFG with a capacity of 15MW and a power generation plant with a capacity of 6MW.
The company has significantly reduced its cost by co-generating electricity by the wasted heat. The WHR unit does not need any externally fed fuel to operate, but it uses the wasted heat from the system as fuel.
The design of these plants hinges around the idea of encapsulating all the wasted heat from the production system and using this heat to generate steam from boilers which eventually runs the turbine engines, thus producing electricity.
Being one of the leading cement manufacturers in Pakistan, Lucky Cement has the responsibility and opportunity to contribute in bringing sustainability in the cement industry. Lucky Cement has extensively invested in implementing projects that reduce energy consumption and address issues of environmental degradation. Projects like Waste Heat Recovery (WHR), Tyre Derived Fuel (TDF) and Refused Derived Fuel (RDF) have not only reduced our production costs, but have significantly reduced carbon emissions.
With these technological developments in place, Lucky Cement has earned precious carbon credits as per the Kyoto Protocol, under the United Nations Clean Development Mechanism for its environment friendly operations and green projects. It is also one of the few companies in Pakistan to report its sustainability performance in shape of a sustainability report, and was the first company in Pakistan to receive an A+ ranking on its sustainability report by the Global Reporting Initiative (GRI) Netherlands.
