Inorganic Chemical Technology

By Prof. Nanda Kishore   |   IIT Guwahati
Learners enrolled: 69
This course is primarily on manufacturing processes of various inorganic chemicals at the industry level. For production of a variety of inorganic chemicals, the basic raw materials requirement, different processes available for the production, flowsheets for such processes, engineering problems associated with such production processes and economics of the processes/materials produced will be discussed. Prior to discussing the production of inorganic chemicals, details of Indian industry along with their current production status and possible improvements discussed in the course. In addition, at the beginning of the course, the discussion of various unit operations and unit processes that form a complete chemical plant, presented in the course.
