  3. @ IIT Madras The Institute Chemical Engineering The Indian Institute of Technology, Madras, is one among the foremost of institutes of national importance in higher technological education and in basic and applied research. In 1956, the German Government offered technical assistance for establishing an institute of higher education in engineering in India. The first Indo-German agreement in Bonn, West Germany for the establishment of the Indian Institute of Technology at Madras was signed in 1959. The Institute was formally inaugurated in 1959 by Prof. Humayun Kabir, Union Minister for Scientific Research and Cultural Affairs. In 1961, the IITs were declared to be institutions of national importance. The IIT system has seven Institutes of Technology located at Kharagpur (established. 1951), Mumbai (established. 1958), Chennai (established. 1959), Kanpur (established. 1959), Delhi (established. 1961), Guwahati (established. 1994) and Roorkee (established. 1847, joined IITs in 2001).   The IIT Madras is a residential institute with nearly 360 faculty, 4000 students and 1250 administrative & supporting staff, is a self-contained campus located in a beautiful wooded land of about 250 hectares. It has been growing from strength to strength ever since it obtained its charter from the Indian Parliament in 1961 and has established itself as a premier centre for teaching, research and industrial consultancy in the country. The Institute has fifteen academic departments and a few advanced research centers in various disciplines of engineering and pure sciences, with nearly 100 laboratories organized in a unique pattern of functioning. A faculty of international repute, a brilliant student community, excellent technical & supporting staff and an effective administration have all contributed to the pre-eminent status of IIT Madras. The campus is located in the city of Chennai, previously known as Madras. Chennai is the state capital of Tamilnadu, a southern state in India.

  4. @ IIT Madras The Department Chemical Engineering The Bachelor of Technology programme in Chemical Engineering was introduced as the first programme when the department was established in 1959. The first set of graduands were awarded their degrees in 1964. Currently the department offers degrees in undergraduate as well as postgraduate level. A strong research programme complements the academic activities. The chemical engineering department has a dedicated and motivated team of faculty actively involved in industrial consultancy and sponsored research at the fundamental level. The faculty is involved in a diverse fields of work including Transport Processes, Reaction Engineering, Environmental Engineering, Biochemical Engineering, Process Control, Polymer Engineering and Particle Science. Collaborations exist between the faculty of the department with those from other departments across the Institute as well as with Industry/Government Organizations on Research Based Consultancy Projects. Sophisticated experimental and computational facilities are available both with in the department and with in the institute.   • Academic Programs • The academic programs of the department include • B.Tech(4 -year program) • Dual Degree(5 year Integrated M.Tech. program) • M.Tech.(2 year program with emphasis on coursework) • M.S.(1.5 - 3 year program with emphasis on thesis) • Ph.D.

  5. @ IIT Madras Faculty & Research Areas Chemical Engineering The faculty, research scholars and students conduct research in a wide range of areas in chemical and related fields.
