Illustrates how triangular diagrams can aid in presenting some of the rather complex transient interactions that occur among gas and surface species during heterogeneous catalytic reactions. The basic equations and numerical examples are described. Classroom use of the triangular diagram is discussed. Several diagrams and graphs are provided. (YP)

This paper describes the development of a software program which incorporates interactive graphics techniques into a teaching and research environment at the Department of Chemical Engineering, Technion, Israel, and the experience of transferring the software from mainframe to personal computer (PC) operating systems at the California Institute of…

Discussed is a method to teach undergraduate students how to complete a conceptual design. Presents three tools to use: (1) how to use order-of-magnitude arguments to simplify problems, (2) how to derive design heuristics, and (3) how to decompose large problems into a set of small, simple problems.

Describes the Heat Exchanger Network Synthesis (HENS) program used at Worcester Polytechnic Institute (Massachusetts) as an aid to teaching the energy integration step in process design. Focuses on the benefits of the computer graphics used in the program to increase the speed of generating and changing networks. (TW)
