Chemical Engineering is one of the most versatile of the engineering programs. It prepares students for employment in many diverse fields, such as production of pharmaceuticals, polymers and plastics, semiconductors, heavy industrial chemicals, synthetic fuels, petrochemicals and petroleum refining. Chemical engineers also work in biological engineering, environmental engineering, enhanced oil recovery, corrosion control, metallurgy and microelectronics. Undergraduate chemical engineering training has been found to be an excellent background for graduate work not only in engineering, but also in a number of other fields, including medicine, law, business, and the natural sciences.

The chemical engineering curriculum is based on a sound background in chemistry, mathematics, physics, and biology. The essentials of engineering are added to this foundation, including fluid dynamics and thermodynamics. In order to develop the individual’s social consciousness and to broaden the student’s educational background, an integrated program of study in the humanities and social sciences is included in the curriculum. Chemical engineering courses in multicomponent thermodynamics, transport phenomena, kinetics, process control and process design are concentrated in the junior and senior years. This program provides training for engineers to enter production, research, product and process development, process design, technical sales and engineering management positions. Training in chemical engineering equips the graduate to solve many of the problems facing society today: human health, energy shortages, synthetic fuels production, water and air pollution, toxic chemical control, and food production. Furthermore, our program prepares students interested in a career in medicine or the life sciences and is suitable for pre-medical and pre-dental students.

The department offers an 18-credit-hour block of approved technical electives. Students select an emphasis in Biological Engineering, Environmental Engineering, Materials Science and Engineering, Chemical Process Industry, Petroleum Engineering, Graduate School Preparation, and Pre-Medicine. Students can also pursue a concurrent major in Chemistry, minors in Physics, Chemistry, Math, Computer Science, Molecular Biology and Business. See department for details. Students are required to take a minimum of 3 credits of Chemical Engineering Technical electives. The Chemical Engineering Program requires that the number of credits of upper division courses be satisfied (ie.,. 10 credits of Technical electives must be 3000+). The Chemical Engineering program requires 48 hours of 3000 and 4000-level coursework. This is fulfilled by required courses and approved technical electives.

Chemical Engineering degree candidates must meet the academic requirements of the college and, in addition, must have a GPA of 2.000 in Chemical Engineering courses attempted at UW that are applied toward graduation for the B.S. degree from the department.

Students must achieve a C- or better in all chemical engineering courses serving as a prerequisite for another chemical engineering course.

Chemical Engineering Program Educational Objectives

Three to six years after graduation, graduates who choose to practice in Chemical Engineering should:

  • Successfully practice the profession of Chemical Engineering;
  • Demonstrate successful career growth

Chemical Engineering Program Outcomes

During the course of study in Chemical Engineering, the student should demonstrate:

  • an ability to identify, formulate, and solve complex engineering problems by applying principles of engineering, science, and mathematics;
  • an ability to apply engineering design to produce solutions that meet specified needs with consideration of public health, safety, and welfare, as well as global, cultural, social, environmental, and economic factors;
  • an ability to communicate effectively with a range of audiences;
  • an ability to recognize ethical and professional responsibilities in engineering situations and make informed judgments, which must consider the impact of engineering solutions in global, economic, environmental, and societal contexts;
  • an ability to function effectively on a team whose members together provide leadership, create a collaborative and inclusive environment, establish goals, plan tasks, and meet objectives;
  • an ability to develop and conduct appropriate experimentation, analyze and interpret data, and use engineering judgment to draw conclusions;
  • an ability to acquire and apply new knowledge as needed, using appropriate learning strategies.

Graduate Study

The Department of Chemical Engineering offers graduate programs leading to the M.S. and Ph.D. degrees in chemical engineering. The M.S. degree is offered under Plan A and Plan B. In addition, an environmental engineering program, run jointly by the Department of Chemical Engineering, the Department of Petroleum Engineering, and the Department of Civil and Architectural Engineering, offers graduate programs leading to an M.S. in environmental engineering under either Plan A or Plan B.

Program Specific Admission Requirements

Admission Process and Requirements

Standard Admission

Admission is open to students with at least a bachelor’s degree who meet the minimum requirements:

  1. A GPA of 3.000 (A = 4.000), or equivalent;
  2. A GRE score (there is no minimum GRE score requirement) 
  3. For international applicants who did not attend an English-speaking program in an English-speaking country for all years of their highest degree:

A TOEFL score of 600 (paper-based), 250 (computer-based), or 80 (Internet based) or an IELTS score of 6.5.

Unofficial transcripts of all prior college-level coursework, test scores and recommendations from three references must be uploaded as parts of the application.

If admission is granted, then official transcripts, GRE and TOEFL scores are required.

Applications submitted by February 1 will be given priority consideration for the fall semester. 

The application will not be processed until all the necessary documents have been uploaded.
