Q1. Scaleup of reactors in a chemical process involves two, somewhat interdependent aspects; selection of the type of reactor to be used and the actual design of the selected type of reactor. List and describe the uncertainties and problem areas involved in the scaleup of homogeneous reaction systems and heterogeneous reaction systems. Q2. Diagrams are used extensively by all disciplines of engineers to convey ideas and data. The process flow diagram is usually the first drawing that will be produced by the process engineer for an engineering or development project. List and describe the ten essential elements of a typical chemical engineering process flow diagram. Q3. A firm is evaluating two competing projects. The first is a new inorganic chemicals plant, while the second is the expansion of a textile fibers facility. The process engineers have estimated the projected annual revenue, total capital investment, and total annual cost (without capital recovery) for each project as follows: Both the new and expanded plants would have an estimated life of 20 years. The firm's marginal acceptable rate of retum is 12.5% before tax, and its marginal federal and provincial income tax rate is 52%. Assuming straight-line depreciation with zero salvage and that 100% of the investment is depreciable, determine which project the firm should fund uning internal rate of return method
