Aims

To understand the need for thorough planning and work monitoring when executing complex tasks, and to have students actively plan and monitor their own design projects.

To understand methods of plant costing and process economics and use the techniques for equipment and process selection.

To understand how to design as a chemical or separation process.

To further develop skills in computer aided process design.

To develop an understanding of the principles of standard and optimisation techniques.

To understand where the techniques can be beneficially applied within the context of process design and operation.


The module covers aspects of process design methodology including design processes and decision making. Design optimisation lectures are supported by a practical exercise utilizing a process flow sheet simulator. Tools for economic evaluation of projects and decision making are introduced and interlinked to the design projects that students have been assigned in CME3039.

Outline Of Syllabus

Introduction to a range of basic decision-making methods from a theoretical as well as practical point of view. Use of software tools to enable practice and exploration of the methods.

Methods for assessing the economics of proposed designs, involving cost and time estimation, leading to financial appraisal.

Revision session on the use of HYSYS process flow sheet software. Development of process flow diagrams, selection of process steps. Computer aided optimisation of process flow sheets.

Unconstrained multivariable optimisation (gradient based techniques, gradient free), Constrained optimisation (Lagrange multipliers, penalty functions etc.), Linear Programming, Application areas (e.g. Optimisation of Reactors, Distillation trains, Predictive Control). Basic scheduling methods

Teaching Rationale And Relationship

Students are introduced to techniques for planning and estimating the cost of complex projects. Design as a process is also discussed and the acquired knowledge is then applied in an assessed assignment. Knowledge and skills are also transferred as a practical set of tools for undertaking the major Stage 3 Plant Design project (CME3039).

Assessment Methods

The format of resits will be determined by the Board of Examiners

Formative Assessments

Formative Assessment is an assessment which develops your skills in being assessed, allows for you to receive feedback, and prepares you for being assessed. However, it does not count to your final mark.

Assessment Rationale And Relationship

The formative online test assesses knowledge acquired and problem solving in a timed environment. The assignment and formative online test provide an opportunity to put acquired knowledge into practice.
