Electives further allow students to tailor their education. Examples include advanced transport phenomena, process control, reactor design, and polymer engineering. Choosing the right specialization and electives can significantly enhance career prospects in specific industries.

B.Tech Chemical Engineering differs significantly from other engineering branches:

• Mechanical Engineering: Focuses on the design and manufacturing of mechanical systems and devices. While both fields involve problem-solving, chemical engineering emphasizes chemical processes and reactions, whereas mechanical engineering focuses on physical systems and motion.
• Electrical Engineering: Deals with the design and development of electrical systems and electronic devices. Chemical engineering involves the application of chemical principles to solve engineering problems, while electrical engineering focuses on electrical circuits and systems.
• Civil Engineering: Concentrates on the design, construction, and maintenance of infrastructure projects. Chemical engineering is more concerned with the transformation of raw materials into valuable products through chemical and physical processes.
• Biotechnology: While overlapping with biochemical engineering, biotechnology is broader, encompassing various biological sciences. Chemical engineering provides a strong foundation in chemical principles and process design, which are crucial for biotechnology applications.
• Environmental Science: Environmental science is interdisciplinary, covering a wide range of environmental issues. Environmental engineering, a specialization within chemical engineering, applies engineering principles to solve specific environmental problems related to chemical processes.

Choosing the right branch depends on individual interests and career goals. Chemical engineering is ideal for those passionate about chemistry, process design, and materials science.

The history of chemical engineering is rooted in the industrial revolution, evolving from industrial chemistry to a distinct engineering discipline. Key milestones include:

• Early Industrial Chemistry: The late 18th and early 19th centuries saw the rise of industrial chemistry, focusing on large-scale chemical production. This period laid the groundwork for chemical engineering.
• Emergence of Unit Operations: In the late 19th century, George E. Davis formalized the concept of 'unit operations,' such as distillation, evaporation, and filtration. This marked a shift towards a more systematic and engineering-oriented approach.
• AIChE's Formation: The American Institute of Chemical Engineers (AIChE) was founded in 1908, solidifying chemical engineering as a recognized profession.
• World War I & Process Intensification: The demands of World War I spurred advancements in chemical processes, leading to process intensification and improved efficiency.
• Post-War Expansion: The mid-20th century saw the expansion of chemical engineering into new areas, including polymer science, biochemical engineering, and environmental engineering.
