HEAT EXCHANGER DESIGN GOALS: Role of heat exchangers in chemical processing Basic concepts and terminology Types of heat exchangers Design methodology Sizing Design Rating

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

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

INTRODUCTION A. Types of Material Balance Problems B. Historical Perspective I. CONSERVATION OF MASS 5 A. Control Volumes B. Holdup or Inventory . Material Balance Basis D. Material Balances II. PROCESSES

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

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

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

.Unsteady, aperiodic motion in which all three velocity components fluctuate→ mixing matter, momentum, and energy. Decompose velocity into mean and fluctuating parts:

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