Chapter 9, Problem 9.34P
Interpretation Introduction

(a)

Interpretation:

The flowchart of the process needs to be prepared, considering absorption and distillation as a single unit.

Concept introduction:

Flow chart is diagrammatic representation of the reaction taking place in the reactor.

ELEM.PRIN.OF CHEMICAL PROC.-W/ACCESS, Chapter 9, Problem 9.34P

The calculation of flowchart is based on the relation

Input-Output=Accumulation

It helps to determine the amount of product formed with respect to the amount of reactant fed to the reactor.

Interpretation Introduction

(b)

Interpretation:

The operating temperature of methanol vaporizer needs to be determined.

Concept introduction

Raoult’s law: This law implies that a given temperature the value of vapor pressure is equal to the product of mole fraction of components and total pressure.

The relationship is gives as

ym×P=Pm×(Tm)

Here,

ym is the number of moles of components

P is the total pressure of components

Pm is the vapor pressure with respect to the temperature (Tm)C

Antoine equation used to determine the temperature using partial pressure in mmHg

log10(P)=ABC+T

P is the vapor pressure in mmHg

T is the temperature in C

A, B and C are the constants with respect to components and temperature

If the vapor pressure in mmHg the calculation of temperature by using relation

T=BAlog10(P)C

This relationship correlates the temperature with vapor pressure.

Interpretation Introduction

(c)

Interpretation:

The feed rate of stream in Kg/hr and product gas composition along with molal flow rate needs to be determined.

Concept introduction:

Mole fraction (yi) of any components given by:

yi=nini

Here, ni is the moles of component i and ni is the total moles of all the components present in the mixture.

The below equation used to calculate the amount of heat transfer

ΔH=ΔH^f+T2T1(cp)dT

Q= Amount of heat transfer

cp is the heat capacity of components

Interpretation Introduction

(d)

Interpretation:

The steam rate generation in kg/hr for waste heat boiler needs to be determined.

Concept introduction:

Relation gives the amount of heat generation:

Q=outnH^iinnH^i

Here,

outnH^i is the heat of formation of product.

innH^i is the heat of formation of reactant.

Enthalpy of reactant and product depends upon the specific heat and the temperature difference.

Interpretation Introduction

(e)

Interpretation:

The impact of steam on outlet temperature needs to be explained.

Concept introduction:

The amount of heat transfer

ΔH=ΔH^f+T2T1(cp)dT

Q= Amount of heat transfer

cp is the heat capacity of components

The concept is based on heat exchangers.
