Use of Process Simulation in Detailed Design

Process Simulation softwares are used in detailed design to finalize or revise sizing based on inputs from vendors and supplier,

  • To finalize process schemes
  • To review and finalize utilities or other process requirements
  • To review and finalize the unit operations required to get the desired product quality
  • To review and finalize the heating and cooling requirement to meet the process requirement
  • To review and finalize the power requirement to meet the process requirement
  • To review and finalize rates of by-products and treatment required for by-products
  • To review and finalize heat and material balance for different cases
  • To review and finalize inputs to various sizing calculations, if applicable, but not limited to
    • Separators
    • Pumps
    • Compressors
    • Heaters
    • Coolers
    • Heat Exchangers
    • Control valves sizing
    • Relief valves
    • Rupture discs
    • Blowdown valve
    • Reactors
    • Furnace
    • Vent/flare header
    • Distillation columns
    • Absorbers columns
    • Stripping columns
    • Condenser
    • Reboiler
    • Flash vessel
    • Pipe sizing
    • Pipeline sizing
    • Flow elements and flowmeters sensors
    • Pressure gauges and sensors
    • Temperature gauges and sensors
    • Level gauges and sensors
    • Interface level gauges and sensors
  • To review and finalize Inputs to other system calculation , if applicable, but not limited to
  • Provide inputs to engineering disciplines such as Mechanical, piping, Instruments, Electricals, Pipeline, safety, etc
  • In some specialize cases; the dynamic process simulation is performed to optimize the system. Few examples are safety system optimization for process safety time, compressor system optimization for control system finalization and review requirement of hot gas bypass, etc.
  • Finalize the design basis, operating philosophies and other documents as necessary
