Chemical and petrochemical engineering is a branch of engineering that focuses on the transformation of raw materials into valuable products through chemical, physical, and biological processes. This course combines principles of chemistry, physics, mathematics, biology, and economics to design, optimize, and operate processes that produce fuels, chemicals, plastics, pharmaceuticals, and other industrial products. Students learn how to develop and manage large-scale manufacturing systems, ensuring efficiency, safety, and environmental sustainability. The course also emphasizes the role of catalysts, process control, reaction engineering, thermodynamics, and material science, especially in the context of the petrochemical industry, which deals with the conversion of crude oil and natural gas into usable chemicals. Graduates are equipped to work in various industries, including energy, materials, pharmaceuticals, and environmental management, contributing to innovations in cleaner production and resource conservation.
