COURSE CONTENT
:
Batch sedimentation, motion of particles in a fluid (Terminal Velocity),
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
develop and 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 limitations. To prepare them for their future research works.
COURSE OBJECTIVE: The main objective of this course is to assist students to carry out experiments
based on fundamental laws and principles of Chemical Engineering processes.
COURSE REQUIREMENT: Students will be organized into group of seven (7) persons. Each group is to
perform each experiment at the appointed time under the supervision of technologists.
COURSE DELIVERY STRATEGIES:Direct interaction between the students and lecturers/ technologists. It
is expected that theoretical principles must have been discussed in class. Lecturer/Technologist will
guide the students during the course of the experiment. Students are expected to submit technical
reports as at the week after the end of the experiments.

LECTURE CONTENT
Week 1-3: Batch sedimentation
Objective: To determine the settling velocity as a function of concentration from batch
sedimentation test.
Description: Sedimentation is one of the methods of separation techniques. It involves
the tendency for particles in suspension or molecules in solution to settle out of fluid
and come to rest against the wall.
Week 4-6: Motion of particles in fluid (Terminal velocity).
Objectives: To verify Stoke’s Law
Description: 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 expressed as:
FD =3ПDPµU where DP= particle diameter, µ= viscosity of fluid= velocity of particle,
FD = 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 for the screens.
Descriptions; Screening analysis is a method of separating particles 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 benzene.
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 coefficient, k,
i.e. CA ⁄ CB=K
Where CA and CB 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 reports by the students and grading of the reports.
