SIMATIC PCS 7 Optimization of Energy Efficiency 1/2 Challenge: § Many process control applications are characterized by facts like: start-up / shutdown procedures, change of operating points, or process-related dependency in closed-loops. This has a negative impact on the energy balance. § Normally, too much energy is used, and this by reduced yield, less throughput and long service life Solution: § Intelligent energy optimization with SIMATIC PCS 7 Advance Process Control Benefits: § Energy consumption is clearly reduced (3 to 10%) because the standard deviation is minimized (up to 200%) and can be adjusted fast § Yield is increased (about 2 to 10%) while energy consumption remains stable § Transition between different operating points is optimized, which leads to faster operating point changes – this reduces energy consumption Page 35 © Siemens AG 2010. All Rights Reserved. Industry Sector

SIMATIC PCS 7 Water & Wastewater Treatment Challenge: § Industrial wastewater treatment plants (e. g. at starch production) require thinning / neutralizing processes with long „dead times“, which are difficult to control from the closed loop controlstrategy point of view § There are processes in industrial wastewater treatment plants, which are represented and automated with standard libraries only in a restricted way § Water / wastewater plants are geographically distributed over a wide area (sewer network, pump stations). The integration of these distributed plants into an comprehensive automation solution is a challenge. Solution: § Intelligent plant optimization with Advance Process Control § Optimized solution based on water libraries § Efficient plant management due to the integration of Tele. Control Benefits: § Thinning-/neutralizing-processes are optimized without wasting recourses § The Water Library provides an optimal solution for industrial and commercial drinking water and wastewater treatment plants § The distributed areas of plants are integrated into the total plant configuration in the same Look&Feel. This helps to reduce operating failures by the operators (Tele. Control) Page 39 © Siemens AG 2010. All Rights Reserved. Industry Sector

SIMATIC PCS 7 Reducing emissions Challenge: § Processes that run at a sub-optimal operating point or take too long to switch between operating points waste energy, creating additional and unnecessary emissions. § Faults and malfunctions can have fatal consequences in the process industry, so it is vital to do everything possible to eliminate them. The number one priority is to minimize the potential threats to people, plant and the environment by technical means without any negative effect on the industrial production process. Solution : § Emissions control and prevention with Advanced Process Control § Integration of process safety into SIMATIC PCS 7 Benefits : § Standard deviation is minimized (typically by up to 200%) and optimally controlled lower emissions § Energy consumption is significantly reduced (typically by around 3 to 10%) reduced consumption means lower emissions (COx, NOx, etc. ) § Safety: greater safety for people, plant and the environment (dioxin disaster in Seveso) Page 40 © Siemens AG 2010.
