COURSE CONTENT

:

Batch sedimenta
tion, motion of particles in a fluid (Terminal Ve
locity),

Screen analysis, distribution co
-
efficient of Benzoic acid in Benzene

and water
.


COURSE JUSTIFICATION
:

To carry out experiments in any area of Chemical Engineering.

To
d
evelop a
nd prepare technical report. To analyze and interpret data so as to
establish theoretical
principles. To also provide experience on variety of measuring instruments, learn how to handle them
with skills and appreciate their limitation
s
.

To prepare them for their future research works.


COURSE
OBJECTIVE
:
The main objective

of this co
urse is to assist students to carry out

experiments
base
d

on fundamental laws and principle
s

of

Chemical Engineering processes.


COURSE REQUIREMENT:

Students will be
organize
d

into group of seven (7
)

persons. Each group is to
perform each ex
peri
ment at the appointed time under the supervision
of
technologists
.


COURSE DELIVERY STRATEGIES:

Direct interaction between the students and
lecturer
s
/
technologist
s. I
t
is expected that theoretical principles must have been discussed in class.
Lecturer/
Tec
hnologist will
guide the students during
the
course of the experiment. Students are expected to submit technical
report
s

as
at the
week after the end of the experiments.

Week 1
-
3: Batch sedimentation


Objective
: To determine the sett
l
ing velocity as a function of concentration from batch
sedimentation test.


Description
:
Sedimentation is one of the methods of separation tech
niques
.

It involves
the tendency for particles in suspension or molecules in solution to settle out of fluid
and come to rest again
st

the wall.


Week 4
-
6
: Motion of particles in fluid (Terminal velocity).


Objectives
:

To verify
S
toke

s Law


Descriptio
n
:

When a flow occurs around an immersed body, it experiences a force
known as drag force. The drag remains
the
same when the body moves through the
fluid as the relative motion remain the same. Stokes’ law is valid for NRE
<
1 and can be
mathematically ex
pressed as:

F
D

=3
П
D
P
µU where

D
P
= particle diameter,

µ= viscosity of fluid= velocity of particle,

F
D

= drag force



Week 7
-
9:

Screening Analysis


Objective
:

To
introduce the students to

the use of standard sieve in analysis of
particulate fluids
.
To determine efficiency fo
r the screen
s
.


Descriptions
; Screening analysis is a method of separating particle
s

according to size
alone. Material pass through a series of screens of different size and are separated into
sized fractions .i.e. fractions in which both the maximum and
minimum particle sizes are
known.


Week 10
-
12
: Distribution co
-
efficient of Benzoic acid in Benzene and water.


Objectives
: To determine distribution of benzoic acid and between water and benzene.

To
determine
the
degree of association of
the
acid in ben
zene.

Description
: Solute distributes itself between a pair of solvents according to the
partition or distribution law which states that the ratio of concentrations in the two
solvents at equibrum is a constant, known as the partition or distribution coeff
icient, k,
i.e. C
A


⁄ C
B
=K


Where C
A

and C
B

are the concentrations of the solute in the solvent A and B respectively




WEEK 13
-
14
: Write
-
up of Technical report.


Description: Write
-
up of entire Technical report.


WEEK

15: Submission of Technical report
s

by the students and
grading
of

the
reports.
