CHEN30150 Chemical & Bioprocess Engineering Design

Academic Year 2022/2023

This module will introduce students to the basic principles of chemical engineering process design, with specific emphasis on equipment design and specification, in the context of a typical design project, in a manner consistent with IChemE-design guidelines. Topics covered include design methods to ensure the safe operation of equipment, selection of materials of construction, safety and loss prevention in equipment design and quality assurance techniques with which the integrity of the design process can be guaranteed. Emphasis will be placed towards sustainability and environmental impacts of design projects and their regulatory compliance, and all of these aspects will be embedded in a fundamental way in the course instruction and examples/case studies. A number of projects will be completed as part of this module. A summary of key conecepts is as follows:

Introduction
Basic principles for pressure-vessel design
Combined-stress analysis
Control of exothermic reactions
Pressure relief
Piping design
Selection of materials of construction
Regulatory aspects for process design and operation
P&IDs, PFDs and plant-layout and utility flowsheets, together with equipment-spec sheets
Control schemes
Safety, environmental and sustainability in process design
Quality assurance
Hazardous materials
Basics of Plant Layout & Economics
HAZOP

Learning Outcomes:

On completion of this module students should be able to:
1. Estimate the shell thickness for a standard pressure vessel, using relevant design codes.
2. Size a relief valve for a variety of upset scenarios.
3. Demonstrate knowledge of safety and loss prevention in process design and operation.
4. Select a material of construction for a specific application.
5. Complete a simple design project as part of a team.
6. Demonstrate an understanding of the regulatory framework for equipment design.
7. Show a detailed understanding of safety, loss prevention and design practice in the context of sustainability and ethics.
8.Carry out basic plant layouts and economics exercises.
9. Conduct a HAZOP.

Approaches to Teaching and Learning:
This course outlines fundamental aspects of chemical engineering design of equipment and processing plants delivered through a face to face lecture course, which is assessed via in class tests. The bulk of the assessment and application of this theory and practice is centred on project work which is intended to closely mimic design practices and processes used by engineers working in industry to design and commision individual pieces of process equipment. In class group process safety HAZOP exercise similarly is conducted using standard industrial methodology also.

Feedback Strategy/Strategies

• Feedback individually to students, on an activity or draft prior to summative assessment
• Feedback individually to students, post-assessment
• Group/class feedback, post-assessment

How will my Feedback be Delivered?

The taught components of the course are assessed through an in class tests where results are provided following assessment. The mechanical design project has initial feedback on the chemical design calculations and TA or Lecturer office hours to address questions relating to the project, throughout its duration with feedback based on a final project grade post assesment. Feedback session on in class HAZOP exercise is conducted following submission of HAZOP report and via assignment grade.
