CONCEPTUAL DESIGN OF SIMPLE DISTILLATION COLUMNS Goals: Determine feasibility of proposed separation Estimate tray and reflux requirements Estimate column diameter and height

EQUILIBRIUM STAGED SEPARATIONS Single Stage Flash [Flash Drum] Distillation Simple Distillation Complex Distillation Non-Ideal Distillation Gas Absorption and Stripping Liquid-Liquid Extraction Multi-Effect Evaporation

THE TWO BASIC INVESTMENT CONCERNS PROFITABILITY (HOW MUCH MONEY WILL I MAKE?) risK (WHAT ARE MY CHANCES OF MAKING IT?)

DESIGN METHODOLOGY: CHOICE OF PROCESS TYPE goaL-- Choose the process type appropriate to the plant to be designed

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