Pieces Letter of Transmittal. This letter on professional letterhead is normally directed to the supervisor who requested that the design work be done. It should be signed by all members of the design team. Abstract. This is a brief description of the design report, focusing on its key conclusions, special features, and assumptions in one or two paragraphs. These include projections of any applicable economic measures (e.g., the return on investment and the net present value) and recommendations to management. Care should be taken to report only significant figures.

Project Report Process Flow Diagram and Material Balances. This is the detailed process flow diagram discussed in Section 2.5 and shown for a vinyl-chloride process in Figure 2.17. All of the streams are numbered clearly and all of the process units are labeled. At some point on the arc for each stream, the temperature and pressure should appear or the information should be tabulated (e.g., see Table 2.7). Note that, as mentioned in Section 2.5, many software packages are available to simplify the preparation of flow diagrams, most notably those associated with the process simulators. Description of the Process. This report item provides an explanation of the flow diagram. The detailed description describes the function of each equipment item and discusses the reasons for each particular choice. Energy Balance and Utility Requirements. List of Equipment and Unit Description. In this report item, every process unit in the flow diagram is described in terms of its specifications and the design methodologies (e.g., the methods for estimating the heat-transfer coefficients, the rigorous design of a distillation tower by means of a simulation program, the recommendations of industrial consultants), and the data employed (e.g., to characterize the reaction kinetics and vapor liquid equilibria). The important approximations should be discussed as well as any difficulties encountered in performing the design calculations (e.g., in converging equilibrium-stage calculations with a simulator). In addition, the materials of construction should be indicated with the reasons for their selection. In addition, the drawing should contain a material balance block similar to the one shown for the vinylchloride process in Table 2.7, that is, a table showing for each numbered stream: (1) Total flow rate (2) Flow rate of each chemical species (3) Temperature (4) Pressure

Questions for the Week Fewer Questions This Week How do I design an Adsorption Column in Aspen? Aspen Plus does not have an Adsorption Column as it is a dynamic unit operation. Hand Calculations will be fine. An analytical solution for a transient Adsorption column is available in your Mass Transfer book. Equation 17.69 Wankat, P.C., Separation Process Engineering, 2ndEd., Prentice Hall p. 680 note: 1-erf(x) solution This analytical solution assumes a simple linear equilibrium relation between adsorbed amount and concentration in the gas phase. The solution gives the outlet gas concentration as a function of time assuming an empty bed at the beginning. It can also be used to determine the removal of a full bed of adsorbed species as a function of time to account for the regeneration of the bed. See Equation 17.74, note: 1+erf(x) solution We have done and Absorption Column in Aspen in HW 5 Amine Absorber for CO2.

Questions for the Week Can you drive a compressor with excess steam? Yes, you can drive a compressor with any high pressure gas or steam. This is called an expander (a compressor but operated in reverse) that would be mechanically connected to your compressor. In Aspen, there are 3 types of streams - material, work and heat. You can use a workstream to connect the expander to the compressor. Ammonia Reaction Kinetics I have not been able to get Dyson and Simon (or Sanchez and Martin) kinetics to work in Aspen Plus (PFR with Powerlaw Kinetics) Please use Kinetics in HW 3 which come from Tempkin, M. and Pyzev, V., Kinetics of Ammonia Synthesis on Promoted Iron Catalyst, Acta Physicochim, USSR, 12(3)327,(1940)
