Detailed description of topics:

This course provides the fundamentals for conceptually designing processes of energy/chemical plants, where process topologies are derived along with their appropriate mass- and enthalpy-balances. The main focus is on continuous processes. The conceptual process design involves a rough-sizing of key-equipment and delivers a sound evaluation of economical and ecological process parameters, thus determining indicators of sustainability.

The course serves as a preparation for the project-work (‘Process Modeling and Simulation’).

 

The lecture is structured as follows:

1.         Introduction

1.1        Review of reactors and thermal unit operation

1.2        Structure and synthesis of Process Flow Diagram (PFD)

1.3        Choosing physical property models; their relevance for different depths of process-modeling

2.         The ‘Basis of Design’

2.1        Analysis of Basis of Design (conditions of special concern for the operation of separation and reactor systems. Analysis of important process conditions. Economic basis)

2.2        Modes of operation (plant capacities, catalyst activity, on-/off design operation, etc.)

2.3        Development of Block-Flow Diagrams

3.         Mass- and enthalpy balances using process simulation tools

3.1        The recycle-structure of processes

3.2        Specifying process conditions (use of intensive variables, numerical robustness)

4.         Analysis and evaluation of a process topology

4.1        Rough-sizing of key-equipment (key design parameters and rules of thumb for equip. sizing)

4.2        Cost estimation of key-equipment

5.         Optimization of a given process topology

5.1        (Multidimensional) Optimization of process parameters (equation oriented algorithms)

5.2        Process Modifications (Heat Integration, Exergy-Analysis and the Pinch-Method, Modifying operating conditions of unit operations, heuristics)

5.3        Integration of process equipment

5.4        Debottlenecking

6.         Topological optimization of processes

6.1        Optimization Strategies and Short-cut methods

6.2        Engineering- Experience in the Design Process - Heuristics and Guidelines

7.         Optimization of plant operation (using a steady-state framework)

7.1        Data mining and data analysis

7.2        Data reconciliation and validation

Course material:

  • A commented set of slides or course-notes supplement the lectures

References from literature:

  • various

Remarks assessment, entry requirements, etc.:

The evaluation is based on course-accompanying homework exercises and an oral examination

Learning goals:

  1. explain the conceptual layout of processes and to recognize the need for a structured approach

  2. identify the involved unit operations (reactors, heat-exchangers, compressors,…) along with their key design-properties and to list the thermodynamic limitations of the unit-operations

  3. develop a reasoning for the selection of thermodynamic models

  4. develop block-flow diagrams and to systematically approach the basis of design

  5. analyze and evaluate Process Topologies

  6. perform a rough-sizing and cost estimation of key-equipment, and to develop and evaluate process alternatives (Heat Integration, Exergy-Analysis and the Pinch-Method, heuristics)

  7. perform a systematic optimization of a given process topology

  8. describe the state-of-the art in topological optimization and process integration

Computer use:

Two lectures are given in a PC-room demonstrating the use of process simulation software. Example-simulations are regularly accompanying the lectures.

An extensive exercising of the course contents and its application to a real process takes place in a subsequent project 'Process Modeling and Simulation' (wbxxxx).
