CHEMICAL PLANT DESIGN

Scope: Training on technical and economic design studies of chemical and related process plants

Contents: the framework of designer's activities, the evolution of the design project, analysis of system structure, degrees of freedom in a design problem, criteria and methods for selecting design variables, economic design criteria, cost estimation, accounting for risk, utilization of economic criteria, optimization etc

Contents: Usual phases of a design project, technical characteristics of flow sheets, optimum design of distillation columns,  Design of process equipment, rapid, approximate size specification methods for process equipment, heat exchanger networks, energy conservation, piping arrangement, safety, risk assessment, technicall report writing etc

Preliminary design project: the project is carried out by student teams to get direct exposure to various aspects of designing a process plant. Emphasis is given to the early stages of project development. Main activities include a brief market survey, gathering data for raw materials and products, selection of production process as well as preliminary technical and economic calculations allowing assessment of project profitability.

Economic design project: Carrying out this project, on an assigned product, is the basic obligation of students, working as four-member teams. The project is at the "feasibility" level and requires, among other activities, collection of required physico-chemical and other data, selection and/or development of process f1ow diagram, process analysis and simulation, selection of design variables and efforts for process optimization.

Process simulators: Methods of process simulations. The commercial simulator ASPEN is available for special training and use by students.
