Chapter 5, Problem 5.57P

Interpretation Introduction

(a)

Interpretation:

The volumetric flow rate of gas leaving the tower and the partial pressure of ammonia in this gas is to be calculated.

Concept introduction:

The volume flow rate of the gas produced is calculated by the formula,

${\stackrel{·}{V}}_{\text{prod}}=\frac{{\stackrel{·}{n}}_{\text{prod}}RT}{P}$

Interpretation Introduction

(b)

Interpretation:

An explanation of the given process, in terms of a first year student, of chemistry is to be stated.

Concept introduction:

The separation of ammonia from wastewater takes place in two steps. In the first step, lime is added to the wastewater which gives ${\text{Ca}}^{2+}$ and ${\text{OH}}^{-}$. The hydroxyl ions then allows that removal of ${\text{NH}}_4^{+}$ as ${\text{NH}}_{\text{3}}$.

Interpretation Introduction

(c)

Interpretation:

An explanation for installing two-part process by the company and the ultimate fate of the ammonia is to be stated.
