Q1: UNIVERSITY OF LEEDS School of Chemical and Process Engineering CAPE3300 Process Engineering Operations 2023/24 Semester 1 Name:........ Introduction The reports you will be writing in this module are based on experiments already undertaken by others, so it is difficult to be completely original. However, it is worth trying to convey your own interpretation of the experiment and the associated data. Although each report will be distinctively yours, you are required to adopt certain conventions in presentation and format. Guide to Report Writing Presentation Use MS Word to write all reports in A4 format using a 12pt font (Times New Roman) and 1.15 spacing, adding tables and Excel files as graphs as appropriate. For tables, use the Insert Table tool in MS Word to create the table. Always use the standard title page (available on Minerva) for each report and include the following information: ● ● Your name Your ID number The experiment number and title The date the experiment was undertaken The date of the report submission You are required to upload all reports as electronic versions to the VLE Turnitin Submission to allow for plagiarism checking, verification and archiving of the submissions. Always write in an impersonal way, e.g. "The pump was started and its speed was adjusted", not "I started the pump and adjusted the speed." You should normally write in the past tense, although present tense may be used when discussing results. Try to be as concise as possible and remember to paginate the report and apply heading numbering. Format of Reports Specifying an exact number of pages for each report is not practical, as this depends on the experiment performed and the author. However, reports should be written as concisely as possible and limited to the page limits provided below, consisting of the following sections (page limits are indicated within the brackets): 1. Cover page - provided on Minerva. 2. Abstract - max a half page section giving an overview of the experiment and your findings. 3. Table of Contents – an outline of the headings and sub-headings and the pages of each section. Also, include List of Figures and Lists of Tables. 4. Nomenclature - list and define all symbols used in equations. 2 5. Introduction (1 page) — a summary of what you set out to do, mentioning the generic background information and science, together with its relevance to the industry and the intended scope (or objectives) of the experiment. 6. Literature Review (2 pages) – a review on the significance of the experiment in chemical engineering applications; background information, including types and existing technologies; operational concepts; relevant background theory should also be included, not just lists of equations; include figures/diagrams as required; cite enough references. NOTE: Do not copy the information in the handout (mark of zero will be returned). 7. Methodology (2 pages) (a) Equipment - a Pipeline and Instrumentation Diagram - P&ID (showing all the streams or pipes, pumps, valves together gauges/metres). Note: Use the appropriate British Standards Institution (BSI) standard symbols in the Appendix. Include a numbered title caption. Do not copy the diagram in the manual (mark of zero will be returned). (b) A one-page summary of what you actually did, using the third person passive voice, not the procedure given in the manual not. 8. Results (3 pages) – provide an account of data obtained, usually in the form of spreadsheets and/or graphs (again, numbered and captioned). Include curve fitting, error bars, line equation, R2, etc., where applicable. Include sample calculations where appropriate, but not every single one. - 9. Discussion of results – this main section of the report (2-3 pages) should be used to assess the significance of your findings, by critically appraising your results. Any shortcomings and errors should also be noted. That is, comprehensively discuss the results explaining "WHY" the trend of results was obtained. Develop arguments logically and support with theoretical concepts and references, and include discussion on errors. 10. Conclusions - a half page section stating what was done, the essential findings of your work, which can be in the form of an introductory paragraph followed by bullet points if appropriate. 11. References (about a page more than 10, from external sources such as textbooks, journal papers, etc) – list all the references you have cited in the text. Note: It is best to use the Harvard referencing method. Use reliable sources such as textbooks, technical papers and a few web sources. Marking scheme Each report is worth 100 marks and the marking scheme is as follows: Abstract (5 marks) Introduction (5 marks) Literature review (15 marks) Methodology (10 marks) Results (25 marks) Discussion (25 marks) Conclusions (5 marks) References (5 marks) Style/presentation of report (5 marks) 3 Submission and Assessment Both reports should be uploaded to the correct VLE Turnitin Submission before 14:00 hrs on the deadline. Each report will be given appropriate feedback and a provisional grade. Any late submissions (excluding those with approved mitigating circumstances) will be subject to the normal University penalty scale. Health and Safety Procedures Introduction All of the experiments in this module involve some degree of risk, so the following health and safety guidelines are provided to ensure that all students work in a safe and responsible manner. Please read these and make sure that you are familiar with them before starting work. You are expected to follow these safety procedures and to ask instructors if you are unsure about appropriate actions. You must wear a laboratory coat and safety glasses during the experimental sessions, as well as any other equipment provided (such as gloves). Every experiment has been assessed for potential risks and hazards, so make sure that you are aware of these before starting each experiment. Risk assessment forms for each experiment are kept in the laboratory. Although you will be guided through each experiment by a trained instructor, it is your responsibility to read the relevant experimental procedure before starting. The instructor will ask you about the experiment and associated risks at the start of the session; if they consider that you are not sufficiently familiar with these, they are authorized to prevent you from performing the experiment (and, hence, submitting a report), resulting in a mark of zero being recorded for that session. If you fail to obey specific instructions, you will be excluded from the session and a mark of zero will be recorded for that experiment. Legislation and terminology The legislation governing health and safety in the workplace is the Health and Safety at Work Act, 1974. This act represents a framework setting out the scope of the legislation. It is called an enabling act, as it does not contain detailed procedures and regulations. Any relevant procedures and regulations are written under the act and are legally binding. Another important and relevant piece of legislation is the Control of Substances Hazardous to Health, 2002 (known as COSHH), which sets out the duties and responsibilities of employers to their employees as well as the duties of people handling the substances. The COSHH guidelines apply to virtually all substances, except asbestos, lead, substances which are radioactive or have flammable properties, and biological agents. For the vast majority of chemicals (including those used in these experiments), the presence of a warning label will indicate whether COSHH is relevant. Complying with COSHH involves a number of important actions, including: Assessing the risks to health arising from your work; Deciding what precautions are necessary; Preventing or controlling exposure to any hazardous materials or substances; Ensuring that control measures are used and maintained properly; 5See Answer
Q2: 3MS Multiphase Systems Problem Sheet 2024 Maximum THREE pages excluding cover page and references. The figures and table below present data from a study of a mixing vessel operated either with gas sparging or with solids. The details of the set up are shown in Figure 1 and Table 1. Experimental Setup and Data Air in Perspex Baffle Ring sparger Rushton 6-Blade Turbine ERT Linear Probe Electrode strip Figure 1. Experimental set up equipped with Linear Electrical Resistance Tomographic Apparatus. This geometry is different to the circumferential geometry used in 2nd year labs. The liquid is conductive (assume the density and viscosity are that of water and an interfacial tension of 0.04 N m¹), and the probe measures the distribution of conductivity in a 2-D radial slice from the impeller axis to close to the vessel wall. When a conductive aqueous solution is sparged with (non-conductive) gas bubbles, the conductivity distribution can be converted to a tomogram showing the distribution of voidage (air bubbles). Table 1. Tank Dimensions.

IMPORTANT: you must state your ID and the corresponding parameters on the cover page of the submission). Figures 2 and 3 show observations and measurements of gas distribution at various characteristic conditions as impeller speed increases for fixed gas volume rate. Figure 2 shows an image of the gas in the vessel and the corresponding tomogram of voidage (εg). (a) Flooding (b) Loading (c) Loading (d) Completely Dispersed/Recirculation (e) Completely Dispersed/Recirculation The average voidage vs depth has been determined from the tomograms and is shown in Figure 3. 2 70 (a) (b) (c) (d) (e) εg (%) 0.00 3.75 7.50 11.25 15.00 Figure 2: Vessel and tomogram images at increasing impeller speed (left to right) and constant gas volume rate.

Using your value for vvm, estimate the likely ranges of impeller speeds for each of the three conditions observed in Figures 2 and 3. [25%] 2. Pick a speed in each range (flooding, loading and complete dispersion/recirculation) and at each determine the power input, assuming no losses due to gassing. [15%] 3. Estimate the maximum bubble size at each of your three speeds [HINT - see UNIT 10 of Prof. Simmons' notes]. Compare qualitatively with Figure 2. [15%] 4. For ERT to work it is necessary that the liquid is conductive. If we are using water, then electrolytes must be added. Discuss the effect on bubble size versus a pure liquid. [15%] Stainless steel balls were added to the vessel and mixed without sparging. In this case the particles are conductive. Figure 4 shows mean conductivity in the radial plane vs height for three impeller speeds NJS, 2/3NJs and Njs.
