4. For the same total initial feed rate Fao, which give the smallest total volume; two equal sized plug flow reactors connected in series or connected in parallel? (For the parallel system, consider the molar flow rates to each reactor the same.) FAO or FAO

1. You have been recently hired by a large Engineering & Construction company. The company has already prepared the following three principal diagrams; block flow, process flow, and piping and instrumentation diagrams (P&ID). Upon review, you came across a number of issues listed below. Explain what changes, if any, would have to be made to the three principal diagrams. a. The reactor outlet temperature has been incorrectly specified. b. The steam requirement for a heater was calculated incorrectly and is now 20% lower than before. c. Several globe valves have been added to the plant to facilitate manual control in case of issues with the control valves. d. There is a change in the control strategy for a distillation tower bottom level. It has been decided that the level of the distillation tower will be controlled by regulating an existing control valve at the feed line to the tower rather than the tower bottom outlet flowrate. e. A heat exchanger has been eliminated. 2. What type of…

Compare the performance of a PFR reactor to CMFR in series. Please state the similarities and differences

standard Continuous Stirred Tank Reactor (CSTR), fitted with the Rushton Turbine, is containing water at 140 ° C. The vessel diameter is 0.3 m and the impeller speed is 120 rpm. i) Find the specific power requirement. ii) Calculate the impeller speed, if the volume of the reactor increases by 64 times and having the constant specific power. iii) Explain the STR is adequate or not.
