Aqueous A at a concentration CA0 = 1 mol/liter is introduced into a batch reactor where it  reacts away to form product R according to stoichiometry A --> R. The concentration of A  in the reactor is monitored at various times, as shown below: t, min 0 100 200 300 400 CA, mol/m3 1000 500 333 250 200 For the above reaction, what size of plug flow reactor would be needed for 80%  conversion of a feed stream of 1000 mol/hr at CA0 = 1.5 mol/liter?

A reactor is used for oxidation of a chemical compound. The reaction rate constant k is 0.8 h HRT is 4 h. The oxidation efficiency is 96%. Determine the flow regime in the reactor.

A series of reactions carried out in separate containers at a constant volume and a constant pressure. For each reaction, what is the ratio of the final temperature to the intial temperature? (enter answers as simplified ratios) 1) 2CH4(g) + 2O2(g) --> 2CO(g) + 4H2O(g) 2) S(g) + H2(g) --> H2S(g) 3) C2H4(g) + H2(g) --> C2H6(g) 4) 2C2H2(g) + 5O2(g) --> 4CO2(g) + 2H2O(g)

The formation of NO from Na and O is to be carried out in a small batch reactor. As a first approximation, we shall consider that the reaction time is more rapid than the time of cylinder compression, consequently, the reaction takes place isothermally in car eylinder at 2700 K, in a constant volume reactor (cylinder) and under a pressure of 20 atm, the initial concentration of N2 is 0.0696 mol/liter. By a specifying constant volume, we are assuming that reaction take place rapidly with respect to the movement of the piston in the cylinder. Consider that the feed consists of 77% N2, 15% Oz and 8% other gases, which may be considered inert. At this temperature the equilibrium constant (Ke-0.01). The reaction is reversible: Na + 0z + 2NO With a rate equation: Cho -TN, = k ( CN, Co, Ke Calculate: a) The equilibrium conversion of N2. b) The time required to achieve 80% of the equilibrium conversion. The formation reaction rate- constant k at this temperature is 1.11 liter mol.h' Hint: dx…

A binary distillation is performed so that a distillate 94% and bottoms 8% in of the more volatile Component A results. The process shown below reflects one operating condition of a feed stream. Rectification, Stripping and the q-line are all provided on the x-y diagram below. Aling with expected stage for the distillation.. What is temperature of the liquid stream leaving the reboiler? What is the temperature of the vapor stream leaving the feed stage? What is the temperature of the liquid stream leaving stage 2? What is the temperature of the liquid reflux returned to the column? Note: A total condensor is installed.

The following reaction takes place in a catalytic reactor: NO2+O2 → NO3 In the process 1000 mol/s of NO3 are produced. The reaction has 90% conversion and air with 20% excess is supplied. Calculate the flow rates of the system.

In the separation process illustrated below, fresh feed stream F consists of 20% A and 80% B on a mass basis. F mixes with recycle stream R to produce mixed stream M, which enters the separator. The mass ratio of A:B in stream M is 2:3. Product stream P, which leaves the separator at 100 kg/h, is pure A, while waste stream W is 5 mass % A. Recycle stream R is 80 mass % A. (a) Find all unknown stream flow rates. (b) Calculate the recycle ratio.
