Professors R. Bethea, Mann, Parker, Riggs, and Tock; Associate Professor Desrosiers and Heichelheim; Assistant Professor Wiesner; Adjunct Faculty: N. Bethea; Visiting Assistant Professors Iyer and Krishnan.

This department supervises the following degree programs: CHEMICAL ENGINEERING, Bachelor of Science in Chemical Engineering, Master of Science in Chemical Engineering, Doctor of Philosophy. The undergraduate degree requirements appear in the accompanying curriculum table.

Along with the degree of Bachelor of Science in Chemical Engineering, a student may declare a minor in a field of his or her choice. Any required or elective courses in the chemical engineering curriculum may be applied toward the minor, with the approval of the minor department. While declaration of a minor is not required, it is strongly recommended. A minor in chemistry or mathematics can be earned with very few additional hours. An approved minor in Business Administration with a B.S.Ch.E. permits a student to enter the MBA program at Texas Tech with no additional leveling in B.A. or Economics courses.

An agreement has been reached between the Department of Computer Science and the Department of Chemical Engineering whereby degrees in both fields can be earned. The additional semester hours are specified as follows:

Semester hours

MATH 2360, Linear Algebra--3

EE 2372, Modern Digital System Design--3

CS 1462, Fundamentals of Computer Science I--4

CS 1463, Fundamentals of Computer Science II--4

CS 2350, Computer Org. and Assembly Lang. Programming--3

C S 2365, Software Engineering--3

CS 2382, Discrete Computational Structures--3

CS 3352, Introduction to Systems Programming--3

CS 3375, Computer Architecture--3

CS 3461, Concepts of Programming Languages--4

CS 4311, Senior Project Design--3

CS 4312, Senior Project Implementation Laboratory--3

CS elective--3

Total additional specified hours--48

Six of these hours may be used as free electives in the B.S.Ch.E. curriculum, resulting in an additional forty-two hours for the B.S.C.S.

Several substitutions are made in the B.S.C.S. curriculum:

Semester hours

CHE 4343-- for--Math. Prob. & Stat. elect.--3

CHE 2343-- for--Computer sci. elect.--3

CHE 4353, 4153-- for--Computer sci. elect.--4

CHE 3306, or

PETR 3308--for--ENGL 2311--3

Technical or professional development electives required for the B.S.C.S. degree may be selected from required CHE courses. Oral communication is included in CHE 3306, 4121, 4232, 4233, 4354, and 4355.

A minor in chemical engineering consists of 18 or more hours in chemical engineering courses, including CHE 1311, 2311, 3225, 3226, 3321, and 3322. Prerequisites for all of these courses will be enforced.

The profession of chemical engineering combines the principles of physical and chemical sciences with the discipline of engineering to solve modern technological problems, and be of effective service to society. The chemical engineer is largely responsible for the continual development of new processes and new products that have a direct impact on improving the quality of life and the environment. To this end, the Department of Chemical Engineering provides a broad-based program with individual, academic, and professional counseling.

The importance of professionalism in engineering cannot be overemphasized. Chemical engineering students are presented with a code of expected professional behavior and ethics at each academic level, and are required to adhere to it. Copies of these codes are available on request.

The senior-year courses, as indicated in the list of courses in chemical engineering, are taught as a year of professional practice. Professional behavior constitutes a significant portion of grade evaluation in these courses.

The chemical engineering curriculum is sufficiently general that upon completion the student is prepared for a career in any of the process industries which involve chemical transformations. Employment opportunities cover a wide spectrum which includes, among others, petroleum refining, petroleum production, plastics production, basic chemicals, petrochemicals, pharmaceuticals, metal production, textiles, semiconductors, and various biomedical and biological specialties. Many chemical engineers also are directly involved in the design of systems to minimize pollution of our environment or are active with governmental regulatory agencies which set environmental standards.

Continuing advances in the practice of chemical engineering include extensive use of computer simulation and computer control of chemical processes. The Department of Chemical Engineering at Texas Tech has well-established programs in both of these areas. All chemical engineering students must have access to a personal computer running the Windows operating system, including Microsoft Word, Excel, and Mathcad software. Many on-campus classes have their own Internet sites, and some classes are available only on the Internet. For this reason, access to an Internet provider is strongly recommended.

In order to be prepared for professional training as well as to practice chemical engineering professionally, it is essential that the prospective engineer have a good background in the physical sciences, namely mathematics, physics, and chemistry, in addition to the engineering sciences which include basic civil, electrical, and chemical engineering. Summer experience in a chemical processing industry is strongly recommended as part of the preparation for professional practice. In order to illustrate the application of engineering principles, visits to processing installations may be required as part of academic course work.

In accord with the Dynamic Enrollment Management Plan of the College of Engineering, the progress of each chemical engineering student is carefully monitored to ensure that all prerequisites for upper-level courses are satisfied, and that degree requirements will be met in a timely manner. A grade of C or better is required in any course applied toward the B.S.Ch.E. degree. The department uses outcome assessment to monitor quality. Students should expect periodic assessment of technical competence.

Students earning a grade lower than a C in any course will be required to meet with their advisor before the start of the next semester. Any course or prerequisite completed with an unsatisfactory grade must be repeated. Students with unremoved unsatisfactory grades will not be permitted to register in CH E 3226, 3306, or 3322.

Students transferring into this department from other institutions or from another department at Texas Tech must have an overall grade-point average of 2.00 or better, as well as a grade-point average of 2.00 or better in all science, mathematics, and engineering courses. All grades assigned in the matriculation of these courses will be included in the computation of grade-point averages.

In addition to scholarships offered through the University Financial Aids Office and the College of Engineering, the Chemical Engineering Department also offers scholarships to qualified students. The awards are based on consistent academic performance of maintaining a GPA of 3.00 (on a 4.00 scale) or better.

Specification of prerequisites implies all prior prerequisites must have been met.

The following table gives an eight-semester sequence of required courses which must be taken in the order shown as partial requirements for the B.S.Ch.E. degree. The remaining requirements can be taken as the student's load permits, provided all prerequisites are met.
