Original Abstract

A method for an evaluation of the critical velocity in case of two (vapor-liquid) phase mixtures transported in pipelines was developed. This method is based on a theoretical background of complex hydrocarbon mixture thermodynamics with respect to the application in petrochemical industry. Methods published so far are focused on applications in power industry where water-steam two-phase system is considered. The method presented allows to calculate pressure drop, velocity and temperature profiles for two-phase complex hydrocarbon systems and to identify the critical flow presence. In this method the critical condition means a singular discontinuity where the finite pressure and/or velocity change corresponds to an infinitesimal change in space coordinate. An example of applying the method in case of furnace-to-distillation column transfer line is shown. It can be observed that using this method can be considered as a contribution to solving practical industrial cases. This method was verified in the industrial practice for a long time, and satisfying results were obtained.
