Professor Kokossis holds responsibility for three modules in the five-year Diploma undergraduate course, all related to IPSEN research activities. A number of undergraduate dissertations are carried out every year under the supervision of the IPSEN team. Modules taught are:
Chemical Process Design I (7th Semester, 3 ECTS)
This module presents the use of systems and computational methods in the design, synthesis and flowsheeting of chemical processes. Part I – Process modelling and flowsheeting. Classification of flowsheeting technologies. Sequential modular, simultaneous and equation-oriented approaches. Review of basic numerical methods. Precedence order, system decomposition and partitioning. Steward’s method, tearing and popular methods in successive substitution algortihms. Part II – Optimization and synthesis. Basic concepts in constrained, unconstrained and mixed-integer optimization. Superstructure optimization. Synthesis of utility systems. Synthesis of Heat Exchanger Networks. Synthesis of distillation systems. Selection and integration of chemical paths. Syntesis of chemical reactors. Process Operability and flexibilty. The module is assessed by assignments and project work. Computer labs are separately devoted to flowsheeting and synthesis. Using Aspen Plus, computer labs familiarize with basic and advanced functions in flowsheeting. Using GAMS as a platform, simple synthesis problems are explained to familiarize students with optimization and to prepare them for the assignments.

Environmental Assessment and Optimization of Industrial Processes (9th Semester, 6 ECTS)
The aim of the course is to analyze the environment as a recipient of pollution. Mechanisms and familiarizing students with the methodology of industrial processes design to minimize the use of raw materials and energy while maximizing the production of products using environmental criteria. Contents: Criteria and “tools” for environmental assessment in the design and operation of industrial processes. Introduction to the logic and necessity of rational use of raw materials and energy in industry. Environmental Technologies and Reuse and Recycling Technology. Water and carbon footprint. Circle of life. ‘Boundary point’ analysis as a ‘tool’ for the evaluation and environmental optimization of industrial processes. Design of “clean” industries based on the “limit” of water use. Methodology for designing industrial processes to minimize waste generation. Methodology for the design of industrial processes for the re-use of generated waste. Design methodology for the recycling of processed waste through the analysis of the boundary point. Integrated industry design methodology to minimize the production of liquid waste while optimizing the required heat loads. Integrated Design to minimize waste generation and value-added production. By-products of bio-refineries. For more information in Greek visit the School’s website.
