Module Description: This module is concerned with the methodologies to synthesise a safe and effective process design satisfying specific needs, with particular emphasis on sustainability criteria: economic, environmental and social.
Learning Outcomes
On successful completion of this module the learner will be able to:
LO1 Devise a conceptual process flowsheet for a specified objective, e.g. product manufacture;
LO2 Estimate the total capital investment and cost of manufacturing for a process.
LO3 Assess the economic viability of a process plant.
LO4 Assess the environmental impacts of a project, process or product.
LO5 Assess the sustainability of a process.
Pre-requisite learning
Module Recommendations
This is prior learning (or a practical skill) that is strongly recommended before enrolment in this module. You may enrol in this module if you have not acquired the recommended learning but you will have considerable difficulty in passing (i.e. achieving the learning outcomes of) the module. While the prior learning is expressed as named CIT module(s) it also allows for learning (in another module or modules) which is equivalent to the learning specified in the named module(s).
Incompatible Modules
These are modules which have learning outcomes that are too similar to the learning outcomes of this module. You may not earn additional credit for the same learning and therefore you may not enrol in this module if you have successfully completed any modules in the incompatible list.
No incompatible modules listed

Requirements

This is prior learning (or a practical skill) that is mandatory before enrolment in this module is allowed. You may not enrol on this module if you have not acquired the learning specified in this section.

Module Content & Assessment

Indicative Content
Process design strategy
Synthesis of elementary process flowsheets. Use of hierarchical technique (input-output, functions, operations) to generate base case designs and flowsheet alternatives for realistic processes. Adaptation of the hierarchical procedure to address multi-phase, e.g. solids processes, or to address specific concerns, e.g. waste minimisation. Criteria for success: technical, economic, safety, environmental, social. Information flows in process plant projects. Inter-relationships between engineering disciplines. Stages in a design and associated timings and level of detail.
Batch processes
Determination of schedule for an elementary batch process. Calculation of cycle time and makespan. Impact of structural flexibility: parallel units, transfer policies, intermediate storage. Impact of scheduling policies: campaign strategy, duration of production cycles, product sequences. Calculation of batch size, vessel sizes and inventories. Optimum conditions for cyclic operations.
Costing
Cost estimation of process plant. Levels of estimate: timing, data requirements, accuracy. Capital cost estimation: power factors, factorial methods, installation costs. Manufacturing cost estimation: raw materials, labour, utilities, overheads, supervision, insurance, etc. Life cycle costing.
Economic assessment
Measures of profitability. Elementary measures: payback period, return on investment. Cumulative cash flow diagrams. Time value of money: present and future worth of single and regular cash flows. Measures considering time-value: net present worth, equivalent annual worth, discounted cash flow rate of return. Application of profitability measures to projects with equal lives, unequal lives, replacement analyses, consideration of salvage value, incremental and mutually exclusive investments. Capital rationing. Sensitivity analysis of profitability measures: single-parameter variation, multi-parameter variation, scenario analysis.
Environmental impact assessment
Objectives and principles of EIA. Methodology of environmental impact assessment of a project: project phases, environmental topics, comparison of existing environment and proposed development, determination of impact significance. Examination of a scoping study. Public communication. Critical evaluation of recently published environmental impact statements.
Product life cycle assessment
Stages in a product life cycle. Methodology of life cycle assessment. Standards. Strengths and weaknesses. Sources of data. Merits of qualitative life cycle assessment. Software to support life cycle assessment. Evaluation of impacts: environmental themes, eco-points. Assessment of different evaluation schemes. Use of life cycle assessment for process selection and process management. Product improvements: introduction to eco-design, environmental product declarations.
Sustainability assessment
Sustainability dimensions: environmental, economic and social. Environmental aspects: resource consumption, cumulative energy demand, wastes and emissions. Greenhouse gases and carbon footprinting. Economic aspects: eco-efficiency, climate change adaptation, reliance on ecosystem services, altered site and process design criteria. Social aspects: water scarcity and footprinting,
