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

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

DEFINITIONS EQUIPMENT RATING: Given the input streams, operating parameters, and size parameters, determine the equipment performance and output streams EQUIPMENT SIZING: Given the input streams and the performance specifications, estimate the economically important size parameters using approximate methods EQUIPMENT DESIGN: Produce a design in enough detail to guide the fabrication of the item of equipment
