Course detail

Systems Engineering III

FSI-KS3Acad. year: 2011/2012

The course title "Systems Engineering (III)-integration and optimization" covers the number of activities focused on best solution of process plant, its subsystems and individual equipment by systematic way, for both cases - new design solution and retrofit solution for new purposes. Course, besides necessary theoretical background, introduce students through the illustrative practical industrial examples to the following process systems activities:
- initial evaluation of production and product cost based on results of process heat and material balance;
- selection of type of production plant (batch vs. continuous) and its apparatus compound (topology, flowsheeting);
- optimization of operating conditions of key process equipment and its performance (one vs. multistage solution) for selected apparatus composition of process;
- balance of suitable interconnection of process and surrounding plants (total site analysis);
- conceptual optimization of choice process topology with optimum operating conditions - i.e. process integration and integration (synthesis) of process subsystems (HEN subsystem, subsystems of hot and cold utilities);
- integration, optimization and detail design of important individual process equipment;
- application of optimization in common engineering practice (optimization of pipelines and insulations, algorithms for selection of suitable types of process equipment, etc.).
