Chapter 8, Problem 8.104P

Interpretation Introduction

(a)

Interpretation:

Calculate the feed rate of the crystallizer.

Concept introduction:

The energy is transferred from higher temperature body to the lower temperature body.

For enthalpy balance of in and out from the process as follows:

$\Delta H_{solution}=\sum _{out}{n}_i{H}_i-\sum _{in}{n}_i{H}_i$

Where, n = moles and H = enthalpy

Interpretation Introduction

(b)

Interpretation:

Calculate the production rate of trihydrate crystals and the mass flow rate of the liquid solution.

Concept introduction:

The energy is transferred from higher temperature body to the lower temperature body.

For enthalpy balance of in and out from the process as follows:

$\Delta H_{solution}=\sum _{out}{n}_i{H}_i-\sum _{in}{n}_i{H}_i$

Where, n = moles and H = enthalpy

Interpretation Introduction

(c)

Interpretation:

Calculate the rate at which heat must be transferred to or from the crystallizer.

Concept introduction:

The energy is transferred from higher temperature body to the lower temperature body.

For enthalpy balance of in and out from the process as follows:

$\Delta H_{solution}=\sum _{out}{n}_i{H}_i-\sum _{in}{n}_i{H}_i$

Where, n = moles and H = enthalpy
