Analysis Of A Vertical Gas Liquid Separator Simulation

Two-phase vertical separators are generally used in the oil and gas industry for gas liquid separation,and efficient gas liquid separation is important to avert downstream process equipment problems and also to meet required export quality.This paper presents a compact vertical gas liquid separator design with an inlet cyclone and a perforated baffle plate internal configuration.The effects of inlet volume fraction variation at 0.75 m/s inlet velocity on the separation performance were investigated for four different inlet liquid volume fractions(0.1,0.15,0.2,and 0.3)by means of Computational Fluid Dynamics(CFD)method.CFD 2019 R3 was used to simulate the turbulent two-phase flow using Eularian mixture and RNG K-epsilon models to evaluate the complex multiflow separation.The simulation results then revealed that the separation efficiency decreases with an increase in inlet Liquid Volume Fraction(LVF).The highest separation efficiency is obtained as 99.9% when the inlet LVF is between 0.1 and0.2,and 11.63% when the LVF is 0.3.Hence,the inlet fluid volume fraction for this study separator was identified regarding the inlet conditions and compact geometry design.
