Chapter 9, Problem 9.17P

Interpretation Introduction

(a)

Interpretation:

The feed rates of the SO₂ and air feed streams and the extent of reaction, e should be calculated.

Concept Introduction

The feed rates and extent of reactions can be better explained on the basis of flow chart formed from the given data.

Interpretation Introduction

(b)

Interpretation:

Calculate the standard heat of the SO₂ oxidation reaction in kJ. Taking molecular species at 25? as references, an inlet-outlet enthalpy table should be prepared and filled in. Write an energy balance to calculate the necessary rate of heat transfer (kW) from the reactor to the cooling water.

Concept introduction:

The standard heat of formation will be helpful to solve the problem as:

$\Delta H_r^0=\Delta H_f^0{}_{(product)}-\Delta H_f^0{}_{(reac\tan t)}$

Interpretation Introduction

(c)

Interpretation:

Calculate the minimum flow rate of heat transfer (kW) from the reactor to the cooling water.

Interpretation Introduction

(d)

Interpretation:

The result if element species is taken into calculation in part (b) should be stated.
