(169b) Novel Control Technique to Optimize Industrial Energy System and Reduce Carbon Footprint

Most large chemical and petrochemical facilities have power and steam generation onsite to reduce operational cost as well as to provide “operational insurance” in the case of a power disturbance from the grid. As a result, these facilities require a sophisticated balance between power generation, purchased power, and power usage to balance loads throughout the plant and ensure safe, reliable operations. In recent years, due to the increased price volatility of power and fuel, the optimum operating scheme for a utility plant will change on an hourly basis. As a result, a plant can take advantage of this fuel and electricity profitability to reduce its operating costs and increase overall steam plant and boiler availability. In addition, the facility’s carbon footprint will be reduced! The objective of this paper is to examine the technical, economic, and process-related challenges in achieving efficient operation of a plant's energy system. Additionally, this presentation will present examples of different cost-reduction projects where advanced automation technologies were utilized.
