ENGINEERING ECONOMICS II INVESTMENT ANALYSIS Companies(and individuals) invest money in order to earn money Examples Build a factory to make washing machines and dryers → Open laundromat Write novel(what is being invested here?) Get a degree in chemical engineering

ENGINEERING ECONOMICS I TO INVEST, OR NOT TO INVEST, THAT IS THE QUESTION. (With apologies to William Shakespeare) Given one or more potential projects, how do we decide in which to invest, if any? What criteria do we use to evaluate potential projects?

CHEMICAL REACTOR CHARATERIZATION GOALS: Outline basic concepts Review reaction chemistry Develop basic definitions of performance Identify important reactor variables Review reaction thermodynamics
