The growing demand for energy combined with increasingly limited natural resources are challenging energy suppliers, industry as well as consumers to use energy as efficiently and sustainably as possible.
Energy-efficient industrial solutions
Considerable energy is used in manufacturing of products before they reach consumers’ hands. In fact,industry is responsible for roughly 34 percent of worldwide greenhouse-gas emissions. This gives industry a special responsibility to continuously improve its efficiency in energy and resource utilization. On the business side, rising prices for energy and raw materials are making efficiency an even more urgent competitive requirement.
Siemens helps its industrial customers to improve their saving potentials with the intelligent combination of consistent, end-to-end processes, targeted services,and an integrated technology portfolio. In this way the entire automation and drive technology of the Henan Zhongfu aluminium hot rolling mill is supplied.The systems and components provide fast production run-up and safe, low maintenance operation.
Intelligent automation
With its open Totally Integrated Automation architecture, Siemens offers a unique suite of products and concepts for optimizing industrial plants. The SIMATIC industrial automatic system and SIMATIC PCS 7 process control system both play a central role. These two systems link and process information from sensors,improve the flow of information and make all types of industrial processes more energy-efficient.
Energy-saving drives
Electric motors like those used for pumps, fans, and centrifuges account for two-thirds of the electricity used in industrial processes. The use of energy-efficient drives can reduce this amount by 15 percent. Drives that use electronic speed control can reduce a pump’s energy demand by up to 70 percent. Siemens offers its customers highly efficient motors for a wide range of uses that can reduce power loss by 40 percent compared to standard motors.
Energy management
Systematic,targeted energy management of existing industrial plants allows the ongoing evaluation of energy flows, making it possible to optimize them. To uncover all potential energy savings in an industrial operation, Siemens has developed a three phases concept : identifying, evaluating and implementing. In the identifying phase, hardware and software identify the energy flows in the plant and uncover the energy-wasters. In the evaluating phase, the potential savings are calculated. Energy-saving programs like SinaSave and SIMATIC Powerrate help provide exact figures on the savings potential. In the implementing phase,specific steps are taken to realize the assessed savings.
