Chemical Engineering

Chemical Engineering definition according to BetaEQ:

“To be a chemical engineer is to deal with processes, projects, quality management, control and optimization. To be a chemical engineer is to manage people, manage a classroom or even a refinery. To be a chemical engineer is to contribute to the growth of the planet. It’s to undertake without forgetting sustainability. It’s to inovate, search and seek for new technologies. It’s to build reactors or even your own company. To be a chemical engineer it’s to believe in the future in the middle of a crisis and win it. It’s to be the thing you wishes the most. It’s to be you.”               (Kaique Santos Teixeira, criador da BetaEQ)

Knowing about BetaEQ’s part in the chemical engineering national scenario, we prepared a series of videos that elucidates absolutely everything about this lovely area. It’s unprecedented, it’s free, it’s exclusive! Excellence is to be BetaEQ!

 “The chemical engineer is the engineer who elaborates projects, installs, operates industries and develops new physico chemical transformation processes. In other words, it’s the professional who participates in every step, since de conception and new industries projects, until the operation, control and optimization of the productive processes.

If chemical engineering could be defined in just one word, it would certainly be “transformation”. The chemical engineering it’s the engineering branch responsible for composition transformation, physical state ou energetic content of raw materials in a series of useful products to the human being.” (DEQUI UFRGS)


The American Institute of Chemical Engineers (AIChE) defines chemical engineering as the “area/profession who dedicates itself to conception, development, sizing, improvement and application of processes and it’s products. This area includes economic analysis, sizing, construcion, operation, control and management of the industrial units that implement these processes, as well as the investigation and formation in these domains”.

The image of the chemical engineer is wrongly linked to pollution, for being responsible of projecting and helping in the chemical industries’s operations, which are potencial generators of pollution.

“Besides this ascription, the chemical engineer possess few professionals capable of decreasing the environmental impact of many industries, not only talking about residues in the industries, but also projecting processes and optimizing the operation in order to decrease the effluent generation and the consumption of important components to the human being, like the water.

The future of industries requires the development of so called clean technologies. Within this scope, a series of actions where the chemical engineer has an important part has been developed in order to decrease the industrial impact on the environment. Some examples can be mentioned like the green plastic, biofuels, and many other actions.

The future perspective for the chemical engineer it’s very promising, not being limited to actions to decrease the human impact above nature. Many currently acting areas, like petroleum, paper and cellulose, and others, will keep their spotlight for the next generations. On the other hand, a series of opportunities sets up as future challenges to our profession:

  • Nanotechnology: it’s associated to the composts production in atomic scale (or nano), where structures and new materials are projected from atoms. Currently, many nano structured products have been studied, among which are medicines, new materials, cosmetics, and others.
  • Bioprocesses: biomaterials processing from agents like enzymes, bacterias and yeasts is the core of bioprocesses. The development of these processes requires not only biological knowledge, but chemical engineer as well in order to approach them to the industrial area.
  • Metabolic Engineering: focus on the compounds production through manipulation of signal transduction paths, through genetics engineer.
  • Green Engineering: products and processes developments where the impact over the environment it’s null or very small. Besides that, the raw materials are renewable sources. An example it’s green plastic, which is being produced from ethanol.
  • Cryogenic Engineering: processes that involve low temperatures. There are cryogenic engineering applications in many areas, like air compounds separation, hydrogen production, and others.
  • Tissues Engineering: this field worries with modeling of the functioning of organs of the human body, like lungs and heart. Besides that, there is the development of biocompatible polymeric materials, which can be uses in the development of tissues and organs.” (DEQUI UFRGS)

CHEMICAL ENGINEERING according to Regional Chemistry Council of 5ª Region.


“It’s important to emphasize that chemical engineering, like all the other engineering fields, applies physical principles while being obliged to apply simultaneously economical principles and human relations. It would not matter for a chemical engineer to design an efficient process in the theoretical point of view, but economically feasible or that it’s forbidden in the environmental point of view or that disrespects security rules of the workers who will enventualy be employed in the processes or yet that it’s against other principles and laws that refers to human coexistence.

The most strong feature of chemical engineering, in comparison with other fields of engineering it’s it extent, a feature that results from it’s peculiar e wide physics, chemistry and mathematics base.” Fonte: CREA-RS.
