GUJARAT TECHNOLOGICAL UNIVERSITY
CHEMICAL ENGINEERING (05)
POLLUTION CONTROL & SAFETY MANAGEMENT
SUBJECT CODE: 2160504
B.E. 6th SEMESTER
Type of course: Chemical Engineering
Prerequisite: Environmental Science
Rationale: The Course focuses on types of pollution, its effects and control methodology along with
industrial law and acts. Safety management part includes engineering principles and methods required for
safety in Industries. This course would educate students to identify and assess hazards in any stage of
operation, to quantify and manage them as well.

environmental protection.
Be aware of the Industrial Laws and Act.
Know about environmental impact assessment and EIS.
Discuss methodology for environmental audit and safety audit.
Be aware of the factors that can lead to an accident.
Learn different methods of hazard analysis and control of hazards.
Discuss source models, dispersion models, fires and fire prevention, explosions and explosion
prevention, pressure relief systems, runaway reactions and risk analysis as they apply to chemical
process safety, and be able to solve corresponding problems.
How to characterize different types of fire and explosions and its control
List of Tutorials:
Students can select any type of industry and learn an existing process used for waste water treatment and
can suggest modifications in process to improve efficiency of treatment. Each group is expected to analyze
the process of manufacturing of the specific chemical assigned to his/her group, with a special emphasis on
safety issues. In addition, each group will be expected to give a power point presentation during last week
of semester. The presenter will be selected randomly just prior to the presentation.

ACTIVE LEARNING ASSIGNMENTS: Preparation of power-point slides, which include videos,
animations, pictures, graphics for better understanding theory and practical work The faculty will allocate
chapters/ parts of chapters to groups of students so that the entire syllabus to be covered. The power-point
slides should be put up on the web-site of the College/ Institute, along with the names of the students of the
group, the name of the faculty, Department and College on the first slide. The best three works should
submit to GTU.
