3. Irreversible consecutive reactions A-Boccur in a jacketed, stirred-tank reactor as shown in Fig. E2.10. Derive a dynamic model based on the following assumptions: (i) The contents of the tank and cooling material in the jacket and in the tank do not vary with time. (ii) The reaction rates are given by iii) The thermal capacitances of the tank contents and the jacket contents are significant relative to the thermal capacitances of the jacket and tank walls, which can be neglected. (iv) Constant physical properties and heat transfer coefficients can be assumed. Feed Coolant out 4-T, Coolant in leir Tei Jacketed reactor Product Figure E3

Question 1) The gas phase reaction (A→ B+C) must be carried out in a fixed-bed tubular reactor using a solid catalyst in a spherical shape of 0.4 cm in diameter. The reactor must operate isothermally at 573 K and an inlet pressure of 1 atm. The reaction is first order and the reactor is fed with pure A at a molar flow of FA0-1 g-mol/s. The internal diameter of the reactor must be 2.54 cm.It is known: -The reaction on the surface of the catalyst is of the type r₁=kCA.; -The particle density gp=2 g/cm3; -The porosity of the bed gl= 0.40.-This reaction, when carried out using the catalyst in powder form, obtained a speed of R 1 10-3 g-mol/g-cat.s, at a temperature of 573 K and pure reagent A at a pressure of 1 atm .-Consider that the reactor is being operated under conditions free from resistance to external mass transfer to the particle.-The effective molecular diffusivity in the gas phase (DAB) to solve this exercise must also be considered constant with the temperature and composition…

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…

You are designing a reactor for a process that has the following decomposition reaction: A →D + 2F The rate law for this reaction is unknown and must be determined by an experiment. Since the reaction takes place in the liquid phase, you choose to build a CSTR reactor. You allow the reactor to fill to a certain volume, V, and then adjust the inlet and outlet volumetric flow rates to equal values, vo, to allow the system to reach steady state. Once the system is at steady state you measure the outlet concentration, CA. The residence time (t = V/v.) is increased by turning off the outlet flow, which allows the volume to increase, then setting the outlet flow to its original value and waiting until steady state is reached. You measure the concentration again and repeat this procedure multiple times to obtain the following table.
