DESIGN METHODOLOGY: INPUT-OUTPUT DECISIONS goaL-- Choose the process chemistry and feedstock most appropriate to the plant to be designed and determine the associated economic potential

DESIGN METHODOLOGY goaL-- Produce design for chemical plant that: Is economically acceptable and Is operable,ie., eIs safe → Is controllable Is reliable,and Is environmentally acceptable

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

WHAT IS ASPEN? A computer program for steady-state process simulation (a.k. process Flowsheeting) Developed for the simulation of Chemical Petrochemical Processes Coal-based Processes Petroleum Refining Polymer Processes One of many commercially available flowsheeting programs such as PROII (Simulation Sciences) HYSIM (Hyprotech) ChemCad(Chemstation)

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

Our research program involves the design, synthesis, and detailed physical investigation of novel molecular and nanoparticle materials which display unique self-organized hierarchical structures and specific optical, electronic, andor magnetic properties. Emphasis is placed on materials with potential applications in light-emitting devices, optical memory devices, molecular level and single particle level switching devices, and chemosensory devices
