Sour water purification method

CHE 482 Chemical Process Design II FALL 2015 SECOND INDIVIDUAL WRITING ASSIGNMENT Discuss sour water stripping with natural gas versus stripping with air. Use only simple text. Show no tables, equations, figures or calculations. This writing assignment must have between 350 and 500 words by “word count.” Divide the second individual writing assignment into the two parts shown below. 1. Write in general terms of the advantage and disadvantages of each method. 2. Discuss how well the ABET “Design Project Assessment Rubric” measures your success on the AIChE project. Design Project Assessment Rubric Course No.: Date: Team/Student: Reviewer: Topic (Weight) Unacceptable (0) Marginal (1) Acceptable (2) Exceptional (3) Points Design Problem and Boundaries Weight: 1 ? Little or no grasp of problem. Incapable of producing a successful solution. ? Some understanding of problem. Major deficiencies that will impact the quality of solution. ? Overall sound understanding of the problem and constraints. Does not significantly impair solution. ?Clear and complete understanding of design goal and constraints, including health and safety. Alternative Designs Weight: 2 ?Only one design presented or clearly infeasible alternative given. ? Serious deficiencies in exploring and identifying alternative designs. ? Alternative approaches identified to some degree. ? Final design achieved after review of reasonable alternatives. Use of Computer–Aided Tools Weight: 2 ? Serious deficiencies in understanding the correct selection and/or use of tools. ? Minimal application and use of appropriate tools. ? Computer–aided tools used with moderate effectiveness to develop designs. ? Computer–aided tools are used effectively to develop and analyze designs. Application of Engineering Principles Weight: 2 ? No or erroneous application of engineering principles yielding unreasonable solution. ? Serious deficiencies in proper selection and use of engineering principles. ? Effective application of engineering principles resulting in reasonable solution. ? Critical selection and application of engineering principles ensuring reasonable results. Final Design Weight: 3 ? Not capable of achieving desired objectives. No implementation of resource conservation and recycle strategies. ? Barely capable of achieving desired objectives. Minimal utilization of resource conservation and recycle potentials. ? Design meets desired objectives. Moderately effective utilization of resource conservation and recycle potentials. ? Design meets or exceeds desired objectives. Effective implementation of resource conservation and recycle strategies. Process Economics Weight: 1 ? No or totally erroneous cost estimates presented. ? Reasonable cost estimates presented, but no profitability analysis included. ? Reasonable profitability analysis presented, but no interpretation of the results. ? Effective use of profitability analysis leading to improvement recommendations. Interpretation of Results Weight: 2 ? No or erroneous conclusions based on achieved results. ? Serious deficiencies in support for stated conclusions. ? Sound conclusions reached based on achieved results. ? Insightful, supported conclusions and recommendations. OVERALL PERFORMANCE ? Unacceptable ? Marginal ? Acceptable ? Exceptional TOTAL POINTS REQUIRED 0–9 10–19 20–29 30–39 ABET Student Outcome (c): an ability to design a system, component, or process to meet desired needs within realistic constraints such as economic, environmental, social, political, ethical, health and safety, manufacturability, and sustainability
