ALEJANDRO-ANTONIO ROMERO is an academic who published a paper in 1989 entitled Phase-splitting prediction in isothermal flash calculations. ALEJANDRO-ANTONIO ROMERO published this work as part of a team: Romero, Alejandro Antonio. Here is a description of this work: The development of processes that operate at conditions where multiple fluid-phase equilibria may occur demands fast and reliable simulation algorithms. The success of these algorithms depends on the correct prediction of the number and compositions of the phases present at a given temperature, pressure and overall fluid composition. The most commonly used routine for this purpose is the isothermal (single-stage) flash calculation. A robust and efficient method to predict phase-splitting previous to performing an isothermal flash is implemented in this work. It is based on the thermodynamic stability analysis of the source phase using a Gibbs energy tangent-plane criterion. Depending on the outcome of the phase-split tests, the system may be declared stable as a single phase and thus no further calculations are needed, or unstable in which case a potential.
