Chemical Engineers (AIChE) Chemical engineers are highest paid! Bachelors Degree Chemical Engineering Mechanical Engineering Computer Science Electrical/Electronics & Communications Engineering Construction Science/Management Civil Engineering Finance Logistics/Materials Management Accounting Nursing Average Salary (2009) $65,466 $58,648 $58,419 $57,404 $52,837 $50,785 $49,794 $49,389 $48,334 $46,655 ~ $15,000 more than Civil Engineering U.S. Employment in 2008 (1,600,000 jobs) 2% of total Bureau Labor Statistics 2010-2011 Report Bureau Labor Statistics Predicted decrease in ChemE employment 2% 2008-2018 Major trends (cont.) Chemicals/Petrochemicals no longer dominant industries Many retirements are expected next decade (2% growth in jobs is expected) but effect of shale gas may revitalize petrochemicals Bioengineering area poses opportunities and challenges: - Perceived as “hot” area: most new faculty in bio area - Biomedical Engineering Depts, are “stealing” students and faculty (Whitaker Foundation provided funding to establish many new Biomed Depts.) Job market biomedical engineers? Many departments (~50%) have been renamed as: Chemical and Biomolecular Engineering (e.g. Cornell, U. Penn., Illinois, Georgia Tech) Chemical and Biological Engineering (e.g. Colorado, Northwestern, Notre Dame, Wisconsin) Major trends (cont.) Nanotechnology is another “hot” area Increasing emphasis on Science in Chemical Eng. Departments - Many professors are not chemical engineers and do not regard AIChE as their primary organization - Has increased multidisciplinary approach - Decreased emphasis on chemical engineering fundamentals - Process Design courses largely outsourced to retired industry people - Process Control no longer required at many universities New major emphasis: energy and sustainability Growing World Energy Demand Most Energy Growth in Developing Nations Sheppard, Socolow (2007) New areas: Energy and Sustainability Fossil fuels with low CO2 impact (petroleum, natural gas, coal) Biofuels (biodiesel, bioethanol, biorefineries) Improved energy efficiency of chemical processes Will require advances in catalysis, reaction engineering and process engineering Challenge: Environmental area was “lost” to Civil Eng. Renamed as Civil and Environmental Eng Departments Remark: Recent interest in Innovation Innovation courses at CMU: Process Design, Product Design, Transport Lab, Unit Ops Lab Impact of trends on curriculum Fewer courses (promoted by deans) Displacement of core subjects to make room for new courses: - 1st & 2nd Law and Phase/Chemical Equilibrium in one Thermo course - Reduction in Transport Phenomena - Elimination of Process Control as required course New courses: biology, biomolecular eng., product design More electives courses: both free / technical 03-232. Biochemistry I Spring: 9 units This course provides an introduction to the application of biochemistry to biotechnology. The functional properties of amino acids, nucleotides, lipids, and sugars are presented. This is followed by a discussion of the structural and thermodynamic aspects of the organization of these molecules into higherorder structures, such as proteins, nucleic acids, and membranes. The kinetics and thermodynamics of protein-ligand interactions are discussed for noncooperative, cooperative, and allosteric binding events. The use of mechanistic and kinetic information in enzyme characterization and drug discovery are discussed. Topics pertinent to biotechnology include: antibody production and use, energy production in biochemical systems, expression of recombinant proteins, and methods of protein purification and characterization. 06-463. Chemical Product Design Spring: 6 units Computer-aided design of a chemical product. Course involves design of molecular structure, microstructure, or devices/processes that effect chemical change. This is a project-based course, for which an extensive report must be submitted Product Design Syllabus: 6 week course Date Tu 3/17 Th 3/19 Tu 3/24 Th 3/26 Tu 3/31 Th 4/2 Tu 4/7 Th 4/9 Tu 4/14 Tu 4/21 Th 4/23 Tu 4/28 Topic Syllabus; Introduction to chemical product design Innovations in product design—History and approaches.

Emphasis is placed on fundamentals, problem solving, self-confidence for developing creative solutions, and techniques for communicating clearly and effectively. The aim is also to make students aware of modern tools and industrial needs, and gain an appreciation of broader societal issues. VISION (2006) Graduates in Chemical Engineering at Carnegie Mellon will obtain employment or attend graduate school, will advance in their chosen careers, and will be productive and fulfilled professionals throughout their careers.

Systems Chem Eng: The Frosh Experience Intro to Systems Intro to Molecular Systems Systems & The Marketplace The Business Connection One trillion dollar industry! Remarks 1. 2. 3. 4. Need to keep core Chemical Engineering Knowledge Need to emphasize fundamentals: basis life-long learning Forecasts are almost always wrong Need to introduce flexibility in curriculum Need to modernize curriculum • Increase exposure molecular level • Increase exposure to energy (alternative/renewable) and sustainability issues • Reflect current technology • Introduce product design but only as complement of process design • Emphasize process operations, enterprise planning • Increase link to other industrial sectors (pharma, electronics) • The curriculum must also emphasize professionalism and ethics • 5. Need to recognize that “bio-area”, while important, will not be dominant force in Chemical Engineering, and emphasis should be on bioprocessing 6. Environmental Engineering will be increasingly important and requires chemical engineering (water use efficiency, pollution control, etc.) 7. Need to provide excitement to recruit the very best young people to join the Chemical Engineering
