Skillful and creative applications of the principles of chemistry, biochemistry, biology, mathematics, and physics are needed to solve the problems now confronting society. Whether these problems involve energy, food, health, materials or environmental quality, the modern chemical engineer is the professional concerned with finding economically and socially acceptable solutions. The program prepares graduates for employment in a great variety of industries including specialty chemicals, petroleum, pharmaceutics, paper, fibers, plastics, food, electronics, consumer products, and environmental remediation. Students may customize their academic program around an industry of interest by judiciously selecting electives. Courses in chemistry, polymers, biotechnology, marketing, and green engineering are common choices.
The objective of the undergraduate program is that within five years of completing their BS degrees, graduates will be successful in a variety of professional careers, including those outside of traditional chemical engineering fields as evidenced by one or more of the following achievements:
- Sustaining a career as a problem solver in engineering or other fields that require analytical skills
- Professional advancement in positions of increasing leadership and/or responsibility within their chosen career field
- Attainment of an advanced degree or advanced certification leading to a career in engineering or science, business, law, medicine, or academia
- Bettering society through professional or personal service
The curriculum has been developed to meet the department goal and the objectives for the graduates. The curriculum is demanding and a GPA of at least 3.0 is recommended for transfer into the program at the sophomore level. An average GPA of at least 2.00 in all CHE courses attempted (except CHE 4144) is required for continued enrollment in the department. The department has specific grade policies for continuation in the program and for graduation. For further information on these policies, please contact the department.
The chemical engineering curriculum integrates studies in thermodynamics, fluid mechanics, heat transfer, mass transfer, process control, reaction kinetics, plant and process design, verbal and written communications, and reaction kinetics, along with professional ethics and environmental awareness. Throughout this curriculum students learn the fundamentals of chemical processing equipment design and operation. In addition, students gain hands-on experience with the equipment during the summer Unit Operations Laboratory. The experience culminates in participation in either a national senior-level design contest or a design project with a local industrial mentor. The laboratory and the senior design courses are recognized as two of the high points in the undergraduate program. The computer is a necessary tool in all the courses and the same software used in industry is used in the design courses.
In addition to the basic undergraduate program outlined here, more sophisticated and specialized programs leading to the M.S. and Ph.D. in chemical engineering also are offered (see Graduate Catalog).
The department participates in the Cooperative Education Program whereby qualified students may alternate periods of study with periods of professional employment.
A total of 131 semester credits are required for graduation in 2021 and 130 in 2022.
The graduation requirements in effect during the academic year of admission to Virginia Tech apply. Requirements for graduation are listed on checksheets. Students must satisfactorily complete all requirements and university obligations for degree completion. The university reserves the right to modify requirements in a degree program.
Please visit the University Registrar's website at https://www.registrar.vt.edu/graduation-multi-brief/checksheets.html for degree requirements.
The following are special focus areas students can use as electives. Lists of approved courses for these focus areas are available in the Department of Chemical Engineering.
- Marketing and Chemical Distribution
- Biochemical Engineering
As part of progress toward a degree, students must have a grade of C- or better in all CHE-prefix courses and maintain a minimum in-major GPA of 2.0 or above (not including CHE 4144). If the in-major GPA drops below 2.0 at any time, students will be placed on departmental probation. Students cannot remain on departmental probation for more than two consecutive semesters. In the case that a student has not achieved an in major 2.0 or better after two semesters, the student must transfer out of the department, is prohibited from registering for CHE courses for at least one semester and, after that, only with permission of Chemical Engineering department head. All CHE credits (except CHE 4144) are used to calculate in-major GPA. Questions concerning progress to degree should be directed to Dr. Whiting.
Students who plan to co-op should talk with Dr. Whiting of the Chemical Engineering department.
For additional information about the Chemical Engineering curriculum, please contact Dr. Goldstein.
The B.S. degree in Chemical Engineering at Virginia Tech is accredited by the Engineering Accreditation Commission of ABET, www.abet.org.
