Specializations in Chemical Engineering

Introduction to Chemical Engineering

Chemical Engineering is a relatively new discipline that is considered interdisciplinary, combining various fields of study. This field initially emerged from Mechanical Engineering, which is why many of the undergraduate courses share similarities with fluid mechanics courses in mechanical engineering. However, there are also several specialized and unique courses tailored specifically for Chemical Engineering, which will be detailed further.

Like other engineering disciplines, Chemical Engineering requires a creative and active mind for designing, calculating, and implementing complex industrial processes. Unlike laboratory-centric fields, such as various branches of chemistry, this discipline, especially at the undergraduate level (and sometimes beyond), does not necessarily require extensive laboratory work; only a limited number of common laboratory courses are offered for introductory purposes during the undergraduate program. However, some concentrations, such as catalysis, thermokinetics, pharmaceuticals, and biotechnology, typically require laboratory work for the completion of theses. Other master’s and doctoral level concentrations may never involve laboratory work and instead focus on programming and computer simulation. Among the most common of these concentrations are simulation, control, optimization, certain separation processes, transport phenomena, and even thermodynamics.

Often, friends or acquaintances preparing for exams may ask about the differences between Chemical Engineering, Pure Chemistry, and Applied Chemistry. Answers to these questions can be found in the written document detailing the distinctions between these fields.

Relevant High School Courses for Chemical Engineering

Considering that some of the key concentrations in Chemical Engineering (such as control, simulation, and separation) often require numerical calculations and even programming, it is advisable for interested students to focus on these areas. It’s essential to have a solid foundation in mathematics, as this will benefit them significantly in their studies.

High school chemistry courses, particularly those related to industrial topics like electrochemistry, plating, and material science, are also vital. Additionally, since Physics courses 1, 2, and 3 are offered in the early semesters at university, it is crucial for aspiring students to have a solid understanding of high school physics, which covers mechanics, heat, and electricity, to avoid difficulties in their studies.

Furthermore, there are a number of ethical and religious studies courses that are commonly required for all engineering students, so all interested candidates are encouraged to familiarize themselves with these topics as well.

In conclusion, it’s important to note that the educational style, content, and classroom dynamics at universities can differ significantly from other educational institutions. What matters most is the effort put into achieving one’s goals; therefore, students are encouraged not to be restricted by past weaknesses (such as poor foundational knowledge or lack of interest) but rather make informed decisions based on a complete understanding of the field. Engineering ethics is often overlooked but is crucial, as negligence in this area can lead to significant consequences. All students are urged to regard this topic with serious attention.
