TINA is a collaborative project between IFP Energies Nouvelles and TOTAL. Objectives are to develop CAPE-OPEN Unit Operations in the field of flow assurance. Therefore, two different kinds of Pipe Unit operations have been developed:

Static pipe

  • Flow under steady-state conditions is solved through the whole pipe
  • Fully compositional calculations are performed
  • 2-phase and 3-phase hydrodynamic correlations are used
  • Thermal exchanges with the surrounding environment are taken into account
  • Several pipe insulation options are available

Transient pipe

  • DFM: Drift Flux Model
  • NPW: No Pressure Wave model
  • Main features
    • Mass, momentum and energy balances are solved
    • Models are fully compositional
    • 2 phase and 3 phase hydrodynamic module has been developed to ensure continuity and derivability of hydrodynamic functions for robust calculations

Furthermore a Simple Transient PI (Productivity Index) module has been developed that correlates the well production rate to the drawdown.

TINA applications have been validated within Aspen Hysys, Aspen Plus, PRO/II, COFE and IndissPlus especially for transient calculations, with also different CAPE-OPEN Thermodynamic Systems such as MultiFlash, Simulis Thermodynamics, TEA.
