Over the years with the great expansion of scientific knowledge, the basis of applying science particularly chemistry to develop technology has increased tremendously. This has lead to the development of the profession of chemical Engineering. Chemical Engineering involves the design and maintenance of chemical plants and the development of chemical processes for converting raw materials or chemicals into valuable forms including those to remove chemicals from waste materials, to enable large-scale manufacture. It combines knowledge of Chemistry and Engineering for the production of chemicals and related by-products. This branch of engineering is a varied field, covering areas from biotechnology and nanotechnology to mineral processing. It covers various fields of chemical technology in mineral based industries, petrochemical plants, pharmaceuticals, synthetic fibres, petroleum refining plants etc. Chemical engineers design and operate chemical plants and improve methods of production. Chemical Engineering is the apt career for those who have an aptitude and interest to work with chemicals. However Chemical Engineering is different from chemical technology. The former is concerned with the designing, supervision, construction, installation and operation of plants and equipments for manufacturing chemical products and developing new methods of production while the latter deals with the actual production of substances with new properties which require new methods of production in the fields of petroleum refining, fertilizer technology, processing of food and agricultural products, paints and dyes; recycling metals, glass and plastics; cosmetics, mineral based industries and prevention and control of environmental hazards. The work of Chemical Engineers, the most versatile of all engineers, involve the invention, development, design, operation and management of processes in industries. So they combine the work of several fields such as those of chemists, industrial engineers, materials engineers as well as electrical engineers. Chemical engineers are responsible for the availability of modern high-quality materials that are essential for running an industrial economy. They design equipments and operate chemical plants as well as determine the problems and find the best methods of production. The scope for chemical engineers is tend to grow in future due to industrial expansion and the related scarcity of resources needed. They may be demand as they work to create synthetic replacements for those natural materials and resources that are in short supply. Overall chemical engineers could make very important contributions for the improvement and maintenance of the quality of life. Eligibility To become a chemical engineer one should have a graduate degree (B.E / B.Tech) or postgraduate degree (M.E) in Chemical Engineering. There are both degree as well as diploma courses. One can go for the 3 year diploma course after the 10th standard (SSC). The basic eligibility criteria for a BE / B.Tech is 10+2 or equivalent examination, with Physics, Chemistry and Mathematics. Duration : BE / B.Tech courses are of 4 years' duration. Academic Programme : The focus of the BE/B.Tech programmes in Chemical Engineering is on Industrial Chemistry, Polymer Technology, Polymer Processing, Polymer Testing, Polymer Synthesis etc. The ME level course generally offers specialized training and research in the areas like computer aided plant design, petroleum refining, fertilizer technology, processing of food and agricultural products, synthetic food, petrochemicals, synthetic fibres, coal and mineral based industries etc. Selection : Selection to the graduate courses ( BE / B.Tech ) is based on merit i.e the marks secured in the final exams of 10+2 and through entrance exams. Entrance to the IIT's is through JEE (Joint Entrance Exam)and for other major institutions through AIEEE (All India Engineering/ Architecture Entrance Examination) OR their own separate entrance exams and other state level and national level exams. There is also the AMIE (Associate Membership Examination of the Institute of Engineers) which enables working people in the private and public sector, or diploma holders to acquire a Bachelor's degree through distance education for career advancement. Personal Skills : A successful chemical engineer must posses strong technical ability and high motivation. Excellent analytical, communication and teamwork skills is a necessity and the candidate should be hardworking, good at organizing and solving problems. It is also necessary to like working with tools, drawing sketches of complex things and operations, and conceptualising forms and structures. Good computer skill is also essential as they use computer technology to optimize all phases of research and production. As the knowledge and duties of chemical engineers overlap many fields, they must be aware of all aspects of chemicals manufacturing and how it affects the environment, the safety of workers and customers.
