  2. Outline • The origins of chemical engineering • What was it? • What has it become? • What kinds of courses do you take to become a chemical engineer? • What are the opportunities for research? • What kinds of careers do chemical engineers follow? mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept

  3. Overview • Chemical engineering is the discipline that uses a molecular understanding of matter to produce from raw materials in useful quantities, all of the synthetic materials that are used by humankind. • In addition to chemistry and biology, the primary subjects that make this possible are molecular thermodynamics and transport phenomena. • The design part of chemical engineering often involves invention of new materials based on molecular knowledge and creation of new cellular level processes -- yes we use bacteria as chemical factories. mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept

  12. An academic joke • http://www.jokes-for-all.com • At Cambridge University during an examination one day a bright young student popped up and asked the proctor to bring him Cakes and Ale. The following dialog ensued: • Proctor: I beg your pardon? • Student: Sir, I request that you bring me Cakes and Ale. • Proctor: Sorry, no. • Student: Sir, I really must insist. I request and require that you bring me Cakes and Ale. • At this point, the student produced a copy of the four hundred year old Laws of Cambridge, written in Latin and still nominally in effect, and pointed to the section which read (roughly translated): "Gentlemen sitting examinations may request and require Cakes and Ale." Pepsi and hamburgers were judged the modern equivalent, and the student sat there, writing his examination and happily slurping away. • Three weeks later, the student was fined five pounds for not wearing a sword to the examination. mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept

  13. What is chemical engineering? • Chemical Engineering originated with the need to transform raw materials into useful products through chemical reactions. • The reactions were discovered by chemists starting in the 1600’s and by the end of the 1800’s, there was a need to produce large quantities of an ever increasing number of materials. • The “scale-up” of a laboratory reaction (~grams) to a profitable commercial process 106grams) is usually not a matter of just making bigger laboratory equipment (flasks, beaker and Bunsen burners). mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept

  14. (Aside) What is engineering? • “To define it rudely but not inaptly, engineering is the art of doing that well with one dollar which any bungler can do with two dollars.” • -Arthur M. Wellington, The Economic Theory of the Location of Railways, Introduction (6th ed.,1900). mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept

  15. We can also say about chemical engineering ... • Chemical engineers use the principles of engineering analysis and knowledge of chemistry to design, build and operate processes that provide society with items such as: • petroleum fuels, toothpaste, low fat potato chips, paint, plastic for athletic shoes or carpeting, insecticides, pharmaceuticals, computer chips, etc. • If nothing sticks to Teflon, how does it stick to the pan? • How can you make carpet from crude oil? mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept

  18. ... the future of chemical engineering ... • In the future we might expect: replacement bones, tendons, skin and other organs, superconducting integrated circuits, ceramic and plastic automobiles, nonmetallic bridges and building structures and clothes that don’t get dirty!! mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept

  23. Bad sports clichés • http://www.sportscliche.com • They wanted it more than we did. • We beat ourselves. • We didn't maintain the intensity for the entire 60 minutes. • We brought our A-game. • I'm really proud of the way our guys hung in there. • He's an impact player. • He's some kind of player.   (Mind telling us what kind?) • You can't say enough about him. • He’s the real deal! mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept

  24. Not a cliché ! • “Chemical Engineering is what chemical engineers do!” J. Wei, Dean of Engineering at Princeton • Chemical Engineers and Chemical Engineering are not defined by what we make, but by the body of knowledge that we learn, our view of the world and the mathematical tools that we use. mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept

  25. What do students take to become chemical engineers? • First let us try still harder to see what chemical engineers need to understand to be able to do what we have seen. mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept

  26. Primary characteristics of chemical engineers • Most all of the products of the world are made of materials that are in a different form from the raw materials from which they were made. • Chemical engineers understand matter in terms of its fundamental nature, • i.e., molecules, • can describe molecules or groups of molecules quantitatively • They use molecular understanding to deal with processes involving chemical, biological and physical transformations of matter • To effectively do this, they can answer the important questions necessary to bridge the gap from molecular sizes up to the dimensions of everyday life. mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept

  27. Comparing different engineering disciplines • A way to think of which kind of engineer you might want to be is to connect with your “inner self” • You know, ... from when you were 10 years old. • Or at least sometime before education changed who you are. • What about the world did you find most fascinating? mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept

  28. Comparing different engineering disciplines • If: • Mechanical engineering inherently deals with all of the mechanical devices of humankind. • Then: • Chemical engineering describes the processes of nature • If • Civil engineering involves the design and construction of large structures. • If • Electrical engineering deals with the materials and processes that allow communication systems and computers. mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept

  29. What do chemical engineers learn about to become one? • Fundamental Science, • Mathematics, Chemistry, Physics, Biology • Engineering science topics: • Chemical Thermodynamics • Transport Phenomena • Integration of these in courses such as • Reaction Engineering, Separation Processesand Process Design mjm@nd.eduhttp://www.nd.edu/~mjmhttp://www.nd.edu/~chegdept
