    What it covers

    Computers have revolutionized the way chemical engineers design and analyze processes, whether designing large units to make polyethylene or small microreactors used to detect biological agents. Nowadays, you no longer have to write your own software programs to use computers effectively. Computer programs can do the numerical calculations for you, but you’ll still need to understand how to apply these programs to specific engineering challenges and validate your solution.This book will:
    • illustrate the problems that you as chemical engineers may need to solve
    • compare the types of computer programs you can use and illustrate which ones are best for certain applications: Excel®, MATLAB®, Aspen Plus®, and Comsol Multiphysics®
    • describe how to check your work to ensure you have solved the problems correctly.

    Suggestions from you

    My plan is occasionally to add a new problem, or explain a new technique. If there are specific things that are unclear in the book, or you are faced with something that goes beyond the book (and is of general interest), please make the suggestion. Several documents are available from DOWNLOADS to make the process easier. Let me know if there are things you would like to see. Bruce Finlayson
