1) Chemical process technology
2) Biochemical Engineering
3) Petrochemical and poly technology
4) Petroleum processing technology
In the final year of the course, students are given the opportunity to select an elective course from one of the areas of specialization given above. In the same year, students work on research project topics which are also selected from the above.
In their project work, students are encouraged to develop indigenous Chemical processes which are appropriate for our specific needs and environment and which utilize our natural raw materials and resources. They are likewise encouraged to design, assemble and construct the equipment needed for their research projects Emphasis is placed on the construction of pilot plan and mini pilot scale equipment in order to afford students the opportunity to work with units which approximate those used in industry.
h) SKILLS ACQUIRED:
A study of our academic programme demonstrates that attention has been paid to Chemical Engineering fundamentals as well as to Chemical Engineering Applications. As is usual in the teaching of Chemical Engineering, we start with Chemical process calculations. This is because the mass Balance and the Energy balance are among the most important fundamental principles in Chemical Engineering. The solution of any Chemical Engineering problem involves the setting up and the solution of a mass balance or an energy balance or both. After this, we introduce the student to Thermodynamics and the unit operations in the second year. Because of the changes in energy which accompany Chemical Processes, thermodynamics is a very important tool in Chemical Engineering to describe such operations in chemical processing as: distillation, crystallization, filtration, size reduction, extraction, absorption, heat transfer, momentum transfer such as in pumping and compression of fluids, fluidization of solids with gases or liquids, two phase transportation of solids by liquids, etc. The term “unit operations” comes from the fact that in a chemical process, which usually contains many of the operations listed above, these operations may be regarded as separate units which may be analysed separately.
Alternatively a chemical process may be synthesized by putting together some of the unit operations listed above. One advantage of the unit operations approach of teaching Chemical Engineering is that analogies are observable in the various unit operation for example, Newton’s law of viscosity in momentum transport, Fourier law of heat conduction in heat transport, and Fick’s first law of diffusion in mass transport, are analogous descriptions of different transfer processes. One will notice that at the time, we introduce a lot of advanced mathematics called Chemical Engineering Analysis which is simply advanced mathematics taught from the point of view of the Chemical Engineer. All these are essential if one is to be a Chemical Engineer capable of facing the challenges in the process industries. These courses continue in the final year after the mandatory 4 months industrial training complemented with a research project which introduces the student to independent research. At this time too, there are elective courses which help to broaden the students’ view of the scope of Chemical Engineering.
i) JOB/EMPLOYMENT OPPORTUNITIES/CAREER PROSPECTS OPEN TO OUR GRADUATES.
Chemical Engineering is that branch of the engineering profession which deals with the manufacture on an industrial scale of useful products from raw material by suitable applications of controlled chemical and physical processes.
Chemical Engineers are employed in a myriad of industries, which may be subdivided as
i. Those that manufacture basic chemicals such as acids, alkalis, metals, salts, and other organic chemicals.
ii. Those that manufacture Chemical intermediate products which are used in further manufacture. Example of such products are: synthetic fibres such as terylene (Dacron), nylon textiles finishing, etc, plastics materials such as polyethene film, styrene for making shoe heels, etc; crude animal and vegetable oils; dyes and pigments.
iii. Those that manufacture finished chemical products which are ready for consumption. Examples are: drugs, cosmetics, soaps, paints, fertilizers, explosives, etc.
iv) Those that engage in the manufacture of iron and steel, petroleum and petro chemicals, pulp and paper, rubber, glass and ceramics, wood processing, leather tanning, dyeing of clothing, etc.
v) Those that engage in food manufacture: This involved refined foods processing e.g. conversion of raw materials into forms more, suitable as food with longer shelf storage and shelf, life. Examples are the Coffee and tea processes, bread manufacture, sugar manufacture, beer, and wine production, milk production industry, rice and cereals, portable water production etc.
vi) Those in the Biochemical Industries and Environmental Control:
these include manufacture of bio-chemical synthesized products, sewage/effluent disposal and water resources management including water treatment plants.
vii) Those that involve nuclear reactions e.gs, the nuclear power plants etc. The scope of the industries mentioned above is large and this is an indication of the versatility of the Chemical Engineer. A fresh chemical Engineering graduate cannot always choose in which of these industries he or she would like to work. The training is broad enough, however, a good chemical engineer should be able to tackle and solve any chemical engineering problem whether he or she is working alone or as a member of a team. This is the reason why in the training of a Chemical Engineer, as is the case with all Engineers, emphasis is placed on fundamental principles. If one knows the fundamental one can tackle and solve new problems when they arise.
In addition to the above opportunities, a chemical engineering graduate can go into design; he can go into teaching; he can go into sales and maintenance; he can go into management, he can go into consulting.
Alternatively, he can establish his own company and become an employer of chemical engineers, rather than an employee Chemical Engineer.
The future for chemical engineering graduates in this country is bright.
With our enormous natural resources there will always be a high demand for chemical engineers. Our oil and gas reserves, our minerals, vegetable resources, etc, will be utilized mainly with the help of chemical Engineers. You only need to be hard-working, imaginative, and unafraid to try new things, enthusiastic, and progressive in your outlook, to be an outstanding Chemical Engineer. The economical disposal of all the waste that spoils our cities is a Chemical Engineering problem. There is no reason why the graduates should not be able to solve this waste-disposal problem, using the Chemical Engineering approach. The sky is the limit for him if he can make use of his potentials.
Chemical Engineering is that branch of the engineering profession which deals with the manufacture on an industrial scale of useful products from raw materials by suitable applications of controlled Chemical and physical processes. It is closely allied with, and considerably overlaps, such other branches as, mechanical Uremic, petroleum, and metallurgical engineering.
Chemical Engineering utilizes the basic principles of mathematics, physics, and Chemistry. The practice of the profession is developed from a combination of these subjects with other specialized branches of the engineering profession as well as the applied, biological and social sciences.
j) PROFESSIONAL BODIES REGISTRABLE:
As students, they are registrable as student members of our profession body- The Nigerian society of Chemical Engineers (NSCHE) which is a division of the Nigerian society of Engineer (NSE).
On graduation, they become professional members after one year of practice in the relevant areas of profession when they apply.
When they further their education and obtain higher certificate they can then apply to become members of the council for the regulation of engineering in Nigeria (COREN).
