What is Chemical Engineering? | Q & A

Chemical engineering is a branch of engineering that combines principles of chemistry, physics, mathematics, biology, and economics to design, develop, and operate processes for the production, transformation, and utilization of chemicals, materials, and energy.

Chemical engineers work on a wide range of projects, including the design and operation of chemical processes for the production of fuels, pharmaceuticals, food, plastics, and other materials. They are involved in all stages of process development, from conceptual design and optimization to construction, operation, and maintenance.

Key areas of focus in chemical engineering include:

• Chemical process design and optimization
• Reaction engineering
• Separation processes
• Transport phenomena
• Thermodynamics
• Process control and instrumentation

The field of chemical engineering emerged in the late 19th century with the development of chemical industries and the need for systematic methods to design and operate chemical processes. Here's a brief overview of how chemical engineering began:

1. Emergence of Chemical Industries:

   • 
     
   • The Industrial Revolution in the 18th and 19th centuries led to the rapid growth of chemical industries, including the production of chemicals, pharmaceuticals, fertilizers, and food products.
   • As chemical processes became more complex and large-scale, there was a need for systematic methods to design and operate these processes efficiently.
   • 
     

2. Foundations of Chemical Engineering:

   • 
     
   • The field of chemical engineering began to take shape in the late 19th century with the work of pioneers such as George E. Davis, Lewis M. Norton, and William Hultz Walker.
   • These early chemical engineers developed systematic methods for the design and operation of chemical processes, including the use of mass and energy balances, chemical kinetics, and thermodynamics.
   • 
     

3. Development of Academic Programs:

   • 
     
   • The first academic programs in chemical engineering were established in the early 20th century, including the School of Chemical Engineering at the University of Manchester in 1888 and the Department of Chemical Engineering at the Massachusetts Institute of Technology (MIT) in 1888.
   • These programs provided formal education and training in chemical engineering principles and practices, and helped to establish chemical engineering as a distinct discipline.
   • 
     

4. Advancements in Process Technology:

   • 
     
   • Throughout the 20th century, chemical engineering continued to evolve rapidly with advancements in process technology, materials science, and computational methods.
   • Chemical engineers played key roles in the development of new chemical processes, materials, and products, and in the design and operation of large-scale chemical plants.
   • 
     

Since its inception, chemical engineering has played a crucial role in the development of chemical industries and in addressing global challenges such as energy sustainability, environmental pollution, and public health. It is essential for the design, development, and operation of processes for the production, transformation, and utilization of chemicals, materials, and energy.
