![]() ![]() Of these two program types, the flash/Gibbs type is gaining pre-eminence because its predictions are available in the phase diagram interior (where many systems operate), whereas the incipient type provides the pressure/temperature (P/T) points of hydrate initiation. Those which predict all phases and amounts at higher pressures and lower temperatures than the incipient hydrate formation point (flash programs, or Gibbs energy minimization programs).Those which enable the prediction of the pressure and temperature at which hydrates begin to form (incipient hydrate formation programs).The most accurate predictions of hydrate formation conditions are made using commercial phase equilibria computer programs. 2.3 Hydrate formation on expansion across a valve or restriction.2.2 Estimating the total amount of MeOH or MEG to inject to inhibit hydrates. ![]() 2 Which hydrate conditions are calculable by hand?. ![]()
