Chapter 1, Problem 1.5P

(a)

Interpretation Introduction

Interpretation:

Volume of the CSTR and PFR reactor had to be determined.

Concept Introduction:

A continuous stirred tank reactor (CSTR) is a vessel to which reactants are added and products within the vessel are vigorously stirred using internal agitation or by internally recycling the contents.

Design equation for a CSTR is

$V=\frac{F_{j0}-F_j}{-r_j}$

Plug-flow reactor (PFR) consists of a hollow pipe or tube through which reactants flow. Water at a controlled temperature is circulated through the tank to maintain constant reactant temperature.

The general equation is

$\frac{d{F}_A}{dV}=r_A=k$

Interpretation Introduction

Interpretation:

Volume of the CSTR and PFR reactor had to be determined.

Concept Introduction:

A continuous stirred tank reactor (CSTR) is a vessel to which reactants are added and products within the vessel are vigorously stirred using internal agitation or by internally recycling the contents.

Design equation for a CSTR is

$V=\frac{F_{j0}-F_j}{-r_j}$

Plug-flow reactor (PFR) consists of a hollow pipe or tube through which reactants flow. Water at a controlled temperature is circulated through the tank to maintain constant reactant temperature.

The general equation is

$\frac{d{F}_A}{dV}=r_A=k$

Interpretation Introduction

Interpretation:

Time necessary to consume 99.9% of species A reactor had to be determined.

Concept Introduction:

A continuous stirred tank reactor (CSTR) is a vessel to which reactants are added and products within the vessel are vigorously stirred using internal agitation or by internally recycling the contents.

Plug-flow reactor (PFR) consists of a hollow pipe or tube through which reactants flow. Water at a controlled temperature is circulated through the tank to maintain constant reactant temperature.

Time can be calculated by using the below equation,

$t={\displaystyle {\int }_{N_A}^{N_{A0}}\frac{dN}{-r_{A}V}}$
