Abstract

Abstract: Aiming at the problem of solid-liquid separation of quench oil and coke particles in a million ton ethylene plant, simulation software was used to optimize the design of large-scale quench oil hydrocyclone with the diameter of 2 meters and the internal flow field and performance of the cyclone were also analyzed by numerical simulation. The large-scale hydrocyclone with the above optimized design has been applied in a million-ton ethylene plant successfully. Combining with the actual application, this paper carried out a study on the characteristics of the equipment under variable operating conditions, and compared the actual operating parameters with the numerical simulation results under the designed operating conditions. The results show that the actual operating parameters were consistent with the numerical simulation results, which indicates that the design method is of great practical value for engineering.

Key words: quench oil, large-scale hydrocyclone, numerical simulation, engineering application
