Utility Systems

CHEN64351 Utility Systems 15 Semester 1 Postgraduate Taught Level 6 Simon Perry Unit coordinator School of Chemical Engineering and Analytical Science 1 FHEQ level (Framework for Higher Education Qualifications) ' Masters/Integrated Masters P4 ' European Credit Transfer & Accumulation System Rating : 7.5 <div> <div> Recent increases in the costs of fuels and power and new restrictions on fuel related emissions (both legislative and financial), have provided additional incentives to examine the provision of heat and power for industrial processes. New and advanced practical tools are now available for targeting, design and operation of utility systems (including cogeneration). This course examines the design and operation of fuel consumers (such as furnaces, boilers and gas turbines) and power generators (such as steam turbines and gas turbines) in the context of the provision of heat and power to a variety of end users. Models and tools are developed that can be easily applied in the design and operation of utility systems in order to minimise operational costs and, where appropriate, to maximise the effectiveness of capital expenditure. In addition, methods and tools are available to examine and optimise these systems in the context of the overall and changing requirements of process users and generators, thereby maximising effectiveness, flexibility and profitability of total sites. Targeting tools, as a basis for utility system design in the supply of heat and power, are also examined and evaluated.Contents            Introduction            Fuels, Combustion, and Emissions            Boiler Feedwater Treatment            Boilers            Basic Steam Calculations            Basic Gas Turbine Calculations            Steam Turbines            Gas Turbines            Gas Turbine Heat Recovery            Steam Use and Distribution            Steam Balances and Energy AuditsOptimising Utility Systems             Utility System / Process Interface            Steam Pricing            Total Site Composite Curves            Cogeneration Targets for Steam Turbine Systems            Optimising Steam Levels            Conclusions</div></div>  <div> <div> Recent increases in the costs of fuels and power and new restrictions on fuel related emissions (both legislative and financial), have provided additional incentives to examine the provision of heat and power for industrial processes.

including cogeneration, in the context of integration with on-site processes.The course will focus on the individual components of the site utility system, targeting for energy use and cogeneration potential, selection of the most appropriate utility system (accounting for cogeneration), the integration of site processes and the utility system, and the minimisation of site energy costs.</div>

lectures, problem solving sessions, and the use of software in solving larger scale problems during timetabled practical sessions. All materials are available via Blackboard including virtual lectures which can assist in the learning process. Communications outside of teaching slots also make use of the Blackboard system.Coursework has been designed in order to demonstrate subject knowledge and competency in methodology, evaluation and interpretation of results, and communication/presentation skills. You will be required to make use of engineering calculations, the use of software, and general problem solving skills. Coursework is required to be submitted via Blackboard and in the form of a hardcopy.</div>   1 Written exam 75% 2 Written assignment (inc essay) 25% Exam: Via examination scriptsCoursework: Via returned papers and within 15 working days CHEN20082 Process Integration Pre-Requisite Compulsory MSc ACE MSc ACE PGDT Taught Component Optional MSc Adv Proc Integration & Des MSc Adv Proc Integration & Des PGDT Taught Component Mandatory N <div> Smith R, Chemical Process Design and Integration, 2005, WileyKemp I C, Pinch Analysis and Process Integration, Second Edition: A User Guide on Process Integration for the Efficient Use of Energy , 2007, Butterworth-Heinemann</div>   Lectures 36 0 118
