Many of the themes introduced in Part I are developed further. For instance, they may be extended to systems in which many chemical species are involved, and there may be time dependency effects. All Part IIA material is "core" chemical engineering, and so the topics in this year are compulsory. The year concludes with a major Design Project.
Fundamentals: The Fluid Mechanics course covers more complicated systems than those described in the Part I course. It includes modelling of turbulent flows, compressible flow, and two-phase flow. The course on Thermodynamics describes phase equilibrium behaviour for mixtures. Radiative Heat Transfer is considered in more detail.
Process Operations: More advanced forms of continuous separations such as (de-)humidification, membrane separations and adsorption processes are considered. The Reactors course covers heterogeneous reactors and catalysts, and considers further the effects of temperature and non-ideal flows. The unit on Bioprocessing extends the Part I course on biotechnology, and includes coverage of downstream processing and purification of bioproducts.
Process Systems: The unsteady-state behaviour of process systems (and their safe operation) is taught in Process Dynamics and Control. The lectures on Heat Integration teach how to use pinch technology to use available energy on a process plant as efficiently as possible.
Enabling Topics: These include a unit on Corrosion and Materials and some other lectures to prepare students for the design project. Further mathematical techniques are also taught including Statistics.
Coursework and Examinations: There are fortnightly continually assessed exercises in the first two terms. These include 'mini-projects' such as literature surveys. The examinations take place at the start of the Easter Term.
Design Project: A full-time Design Project lasting five weeks is undertaken after the examinations. The project involves the conceptual and process design of a whole plant, such as a liquefied natural gas storage facility, a sugar refinery or a hydrotreater to meet the sulphur specification of diesel fuel. The project is performed in groups of about six students, and includes all the important aspects of Chemical Engineering design: process flowsheet development, equipment sizing, control, economics, safety, environmental considerations and reporting/communication. A major feature of the project is the use of modern IT tools such as process simulators, mathematical tools, drawing packages, materials databases and office software to tackle problems and generate reports.
