An efficient and robust algorithm for the calculation of gas-liquid critical point of multicomponent petroleum fluids

摘要: The calculation of critical points in petroleum fluids and other multicomponent mixtures is important for practical theoretical reasons. For certain applications, there a need the point as many 10 8 times with change composition. There currently no algorithm that enjoys both robustness efficiency (that is, speed) to be used such purpose. In this work, we propose simple has remarkable robustness. It orders magnitude faster than existing algorithms which are known robust. © 2006 Elsevier B.V. All rights reserved.
