The Various Fields of Chemical Engineering and What They Entail?

Introduction to Chemical Engineering?

Chemical engineering is an engineering niche that deals with the study of various chemicals, natural resources, and the transformation of raw materials into essential chemicals that are in commercial and public use every day. It is a complex field of engineering that delves solely into the principles of chemistry and chemical reactions. Chemical engineering is applicable in every aspect of our daily operations. Chemicals are everywhere, and in everything we use. Earth is a vast host of thousands of chemicals, found in different ways and forms throughout the planet.

With a diploma in chemical engineering, graduates learn the application of nanotechnology and nanomaterials in large-scale industrial processes that convert raw materials, living cells, and microorganisms into useful products. They also learn the art of designing equipment and processes that refine raw materials by mixing, compounding, and processing chemicals. The leading fields of chemical engineering, namely modelling, chemical reaction engineering, biological engineering, and nuclear engineering, are split into specializations that chemical engineering students can, later on, choose from.

Types of chemical engineering

Indeed, chemical engineering is a vast field of education and many aspiring candidates choose chemical engineering as their degree course. Basically, chemical engineering can be categorised into various parts such as chemical engineering biotechnology, nanotechnology, mineral processing, ceramics, fluid dynamics, environmental science, thermodynamics and material science.

What do chemical engineers do?

In simple terms, chemical engineers design processes that extract chemicals from raw materials and natural resources and convert them into products and services we use every day. The fuel in our vehicles, the makeup on our faces, and the medicine we consume are all products of chemical engineering. Chemical engineers work in labs and workshops to translate practical applications for the commercial production of forms of chemicals. They apply the principles of chemical engineering and study maths, physics, and chemistry.

As a chemical engineer, you'd work in large-scale research facilities, pilot plants, manufacturing plants, and cosmetic plants. The leading industries employing chemical engineers are food, processing, fuels, biological, medical, and pharmaceuticals. 21st-century chemical engineers also work in making sustainable and environmentally friendly factory production methods to minimize harm and costs.
