Task # 3

CA=0.0672 mol/L

3.2

There is an operating accident where the feed flow with A is interrupted and the concentration of A drops to 0 inreactor. How long will it take for the feed to resume (ν0 = 0.12 l / s, CA0 = 0.3mol / l) before a steady state is obtained, i.e. the concentration A in the reactor is equal to thatfor the stationary state.

Answer #1

A homogeneous liquid phase reaction A -> R, rA = -kCA^2 takes
place with 50% conversion in a mixed reactor (CSTR). What will be
the conversion if this reactor is replaced by one 6 times as
large-all else remaining unchanged?

An isothermal CSTR with a first order irreversible reaction A
—> B and rA = 0.14 mol/(ft3*min) has a constant flow rate of 11
f3/min. The reactor volume is 100 ft3. The inlet concentration CAi
changes from 6 to 5.5 moles/ft3 (a step change). (a) Determine the
process time constant. (b) Determine the steady state gain.

Consider the CSTR with first order reaction and the process
parameters and variables are given by: The process parameters and
variables are defined as: CA0 = feed concentration = 2.7 mol/L. Cp
= heat capacity of the reactor feed and product (1000 cal/kg*K) =
Cv. E/R = normalized activation energy (20,000 K). F = mass feed
rate and product rate (10 kg/s). k0 = rate constant (1.97×10^24
1/s). Q = heat addition rate (initially 700,000 cal/s). T0 = feed
temperature...

Homework 3 Problem: A reaction A->R takes place in a
constant-volume isothermal CSTR. The component mass balances
are:
r= dCa/dt= Cai - Ca - KCaٍ
r= dCr/dt=Cri-Cr +KCaCr
where: CAi: feed concentration of A (input); CRi: feed
concentration of R (assumed constant); CA, CR concentrations of AR,
respectively, in the reactor and outlet; r,k, positive
constants.
a) Linearize the equations around the design steady-state (CAis
,CA, CR) and put them in deviation variable form.
b)Calculate the transfer function between CR...

A first order, liquid-phase reaction A ?products, is conducted
in a 2000 L CSTR. The feed contains pure A, at a rate of 300 L
min-1 , with an inlet concentration of 4.0 mol L-1 . The following
additional data are available:
cP = 3.5 J g-1 K-1;
? = 1.15 g cm-3 ;
?HRA = -50 kJ mol-1
(you can assume that these values are constants)
kA = A e-EA/RT = 2.4 x 1015e-12,000/T min-1 , with T in...

Problem 1 Consider the liquid phase reaction A à products
accelerated by a homogeneous catalyst dissolved in the solution.
The observed rate data follows the form:
-r=k1Ca/(1+K2Ca+K3(Ca^2))
You are asked to recommend either a steady CSTR or steady PFR.
Your reactor must reduce the feed composition of 0.6 mole/liter
down to 0.3 mole/liter in the effluent. • Create a plot of ordinate
1/(-rA) vs. abscissa CA. Use the data below. Use sufficient
resolution in your plot to get a smooth...

A liquid phase reaction A+B --> C+D is to be carried out in
an isothermal and well mixed batch reactor. The initial moles of A
and B are both 0.1 mole. The rate of destruction of A is
given by –rA = k*CA*CB, with k
= 6.0 L/ (mol*min). Calculate the amount of
time (in minutes) that the reaction must proceed within a 10 L
reactor in order to achieve a final concentration of A of 0.001
mol/L. Please express your answer to...

The elementary irreversible organic liquid-phase reaction, A + B
→ C, is carried out in a flow reactor. An equal molar feed in A and
B enters at 27 oC, and the volumetric flow rate is 2 L/s. The feed
concentration is CA0 = 0.1 mol/L. a) Calculate the PFR and CSTR
volumes necessary to achieve 85% conversion when the reaction is
carried out adiabatically. b) What is the maximum inlet temperature
