Energy and Environmental Engineering Systems Air Pollution Modeling, Simulation, and Control Refinery modeling, planning, and optimization Sustainable Development of the Petrochemical Industry Planning and Scheduling of Process Operations Dynamic Modeling and Optimization Combinatorial Optimization Soft Computing Uncertainty in Optimization Process Modeling and Simulation Computer-Aided Product Formulation and Design Traditionally, PSE has been concerned with the understanding and development of systematic procedures for the design and operation of chemical and biochemical process systems, ranging from microsystems to industrial scale. Recently, the scope of PSE has been broadened to include systems at larger scales such as supply chains and the business enterprise, and at much smaller scales such as molecular and atomic systems. The use of PSE enables companies to operate inherently safe processes while at the same time reduce production costs, improve quality, increase efficiency, reduce pollution, and bring products to market faster. The long term research objective of my group is to further extend upon the existing PSE toolset and integrate environmental impact assessment tools. Unlike the traditional approach that focuses on man-made systems and treats environmental requirements as constraints, we will stress on the interactions between process systems and the natural system with the aim of establishing a harmonious social-economical-technological combined systems. Our focus will be on improvements of the existing methodologies in order to create and operate processes which will have minimum environmental impacts and maximum economic benefits in order to reach sustainable development. The consideration of economics along with environmental issues is essential in order to preserve profitability; otherwise investment will not occur and environmental protection will be eroded. Models and tools that can be used to improve the efficiency and sustainability of products and processes will be investigated. These methods will stress on the interactions between the industrial and ecological systems and will treat them as networks of interconnected flows. Our ultimate goal is to contribute to the development of advanced process systems analysis tools that are able to deal with sustainability in a systematic way and will be able to produce ecologically and economically conscious process systems. We envision a set of robust tools that can be used at a variety of decision points in product and process design; including: (1) Process modifications on existing processes to reduce waste and energy consumption, improve efficiency, and use renewable resources (2), Scheduling process operations to minimize pollution under adverse environmental conditions or under changing regulations, (3) Selection of appropriate pollution reduction options from a superstructure of available technologies, (4) Development of new sustainable processes that abide to economic, safety, and environmental considerations, and (5) Suggest robust green energy and power production pathways. At all decision stages, the focus will be on the use of less energy, lower amounts of non-renewable resources, less waste generation, and an increase in the use of renewable resources while at the same time taking into consideration the contribution of ecosystems and hence adopting a broader view which requires an expansion of the analysis boundaries.
