Approaches to Asymmetric Catalysis Organometallic catalysis Broad scope Ligand control Inert conditions -Cost and toxicity Bioorganic catalysis Highly selective High rate of reaction Limited scope
HEAT EXCHANGER NETWORK SYNTHESIS 1: TARGETING OBJECTIVES: 1 Determine the minimum energy inputs required for a process 2Determine the minimum number of heat exchangers required to transfer this energy 3Develop a methodology for determining where these heat exchangers should be placed in the process
MAJOR PROCESS TYPES CONTINUOUS STEADYSTATE- Used for world-scale production of commodity chemicals Large, centrally located plants BATCH Used for small-scale production of high value-added chemicals JIT MINIPLANT Used for on-site production of hazardous or difficult to transport chemicals Continuous Steady-State is the dominant process type
WHATIS DESIGN??? A DESIGN IS PLAN FOR: Manufacturing an artifact refrigerator or a rug Building the mean of manufacture A factory or a chemical plant Building structure A bridge or a baseball stadium Implementing an organization A hospital emergency room A air transportation system
