CHEMICAL ENGINEERING DEPARTMENT

INTRODUCTION

Chemical Engineering is the application of principles of fundamental sciences, engineering, economics, computer technology and human relations to practical situations in fields dealing with processes and equipment in which matter is treated to produce something that is beneficial to the society. Training in Chemical Engineering requires the provision of knowledge, skills and understanding of these principles for the planning, optimum design, construction and operation of new chemical plants and processes, expansion and revision of existing ones with due consideration to the assessment of performance of process and equipment as well as the environment.

The need for the establishment of a Department of Chemical Engineering was recognized, and priority of consideration was accorded it in 1970 at the founding of the Midwest Institute of Technology, Benin, which subsequently became the University of Benin, Benin City.  The establishment of the Department in 1973 with the offering of a programme for the degree of Bachelor of Engineering in Chemical Engineering as one of the two-degree programme in the Department of Chemical and Petroleum Engineering. The programme for Bachelor of Engineering in Petroleum Engineering was the other programme.

Chemical Engineering graduates have numerous employment opportunities in Nigeria. Most of them presently employed in both private and government owned industries which manufacture cement, soaps and detergents, alcoholic and non-alcoholic beverages, pharmaceuticals, textiles, pulp and paper, fertilizer, paints, steel billets and petroleum products, to name a few.

PHILOSOPHY AND OBJECTIVES OF CHEMICAL ENGINEERING DEPARTMENT

The philosophy of the Department of Chemical Engineering includes the contribution to knowledge and material development through full training of first rate moral, academic, physical and entrepreneurial future leaders in technology and socio-economic development in Nigeria. The department has forged extensive links with industries and undertakes tasks for multinational companies and smaller organizations, foreign institutions and professional bodies.

The objectives of the department include the thorough training of highly skilled chemical engineers, the provision of high quality research and consulting services for the need of engineering developments in Chemical, Petroleum and allied industries in Nigeria.

Presently, the department offers the following programmes:

  1. Bachelor of Engineering degree programme (Full Time)
  2. Postgraduate diploma programme (Full Time)
  3. Master of Engineering degree programme (Full Time)
  4. PhD degree programme

The postgraduate diploma programme provides the opportunity of studying chemical engineering for graduates in other field of engineering and the Physical Sciences pursuing careers in Chemical, Petroleum and Allied Industries. The Master of Engineering degree programme provides opportunity for chemical engineers to further enhance their knowledge in the discipline as well as prepare those interested to continue up to PhD level.
