At a recent technical seminar hosted by Mining and Industrial Energy Optimisation (MIEO), experts in energy saving strategies in the industrial and mining sectors shared their ideas. They presented practical options for engineering professionals to implement cost-effective and sustainable energy saving measures in industrial and mining operations.
Delegates learnt about energy saving solutions in pumps and pumping systems; variable speed drives; materials handling systems; compressed air; mining and industrial fans; energy measurement and monitoring; steam systems; and electric motors. In addition, opportunities presented by Eskom’s Demand Side Management (DSM) funding process were covered.
ABB
Robert Fitchet, ABB Drives services manager, showed how energy savings can be achieved through the use of modern variable speed drives. Marthinus Greeff, ABB’s Local business manager for LV Motors, looked at the life cycle cost of an electric motor and concluded that the use of a high quality electric motor can contribute to substantial energy savings in the long term. Another ABB contribution came from Edith Kikonyogo, consulting services manager, who described how ABB’s Global Consulting business helped ArcelorMittal in Europe to realise R150 million in annual energy savings at its integrated steel mill. This was done through the application of a structured Industrial Energy Efficiency programme.
Endress+Hauser
Evan Dent, Business Development at Endress+Hauser, demonstrated the energy saving potential in industrial processes in key energy-using utilities. He presented a monitoring and targeting strategy which can assist in realising sustainable energy savings.
ISO 50001
Ian Langridge, principal electrical engineer at Anglo American, spoke about the new energy management standard, ISO 50001. This will establish a framework for industrial plants, commercial facilities and entire organisations to manage energy, and will have broad applicability across national economic sectors.
The purpose of the standard is to ensure that a credible and effective management process is in place to reach energy use goals. Organisations can set their own goals in accordance with their operational requirements and vision. ISO 50001 will enable businesses to systematically set and reach energy use goals and realise energy cost savings.
The ISO 50001 Management System for Energy (MSE) is on track to become the universally accepted standard. It is estimated by the International Standards Organisation (ISO) that the standard could ultimately influence up to 60% of the world’s energy use.
In the future many government and utility energy programmes will require that an effective MSE be put in place to qualify for programme benefits. While ISO 50001 is only set to be published in 2011, many organisations, among them Anglo American, are already preparing so that they can be certified as soon as the final document is released.
