Introduction Data extraction relates to the
procedure of obtaining the information required
for Pinch Analysis from a given process
flowsheet. It is possible to perform heat
integration analysis for a new project or as part
of a retrofit analysis of an existing process,
which is the case in this paper. The main source
of information is a converged simulation, but
other sources of information such as equipment
placement, automated control strategies, safety
hazards should be considered.
The Main GUI Tab Sheets

• Objectives
• establish the rules for transferring data from
  process simulation software to process
  integration software
• - establish the communication mode with HYSYS
  server and with DPI-UMIST (SPRINT and STAR )
  applications
• - create the software engine for automatic data
  extraction from HYSYS simulation for use in
  DPI-UMIST process integration software
• - checkout the results acquired with the new
  interface (case study)

Stream in process simulation

• Stream in process integration
• The stream data for a process is defined as the
  information relating to the streams which require
  heating and cooling.
• The information required for a stream includes
• supply temperature (TS)
• target temperature (TT)
• heat capacity (CP) (CP m.Cp
• where m mass flowrate).

Conclusions

• PinchTech is a evolutive instrument, which can
  be easy used for extracting
• data from HYSYS simulation
• PinchTech extracted data are in good
  concordance with manually extracted
• data
• For complex HYSYS simulations the time required
  for data extraction is
• significant reduced
