BASIC LEVEL II DECISIONS Choice of reaction chemistry Choice of raw material feedstocks Determination of need for vapor recycle Evaluation of economic potential for process

ESIGN METHODOLOGY III: RECYCLE STRUCTURE OF THE PROCESS goAL-- Determine alternate recycle structures for the process based on reactor operating requirements

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 ESTIMATING THE PROFITABILITY OF A CHEMICAL PLANT Estimating Investment Estimating Cost of Production Profitability Evaluation Return on Investment (ROD) Payout time(Tpay) DCF Rate of Return(DCFROR) Transfer Price

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?

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)
