Abstract: Among the various components that affect the performance of multi-phase separators, vane type demisters are particularly significant. In this study, we evaluate a chosen correlation by considering a gas-liquid separator pilot. In this paper, we utilised the Souders-Brown and Burkholz correlations to design the vane type demisters. We conducted laboratory experiments to investigate the performance of the manufactured vane type demisters under controlled conditions. To minimise the discrepancy between experimental and theoretical outcomes, an adjustment factor must be applied to the equations. Additionally, we developed a CFD model to simulate the vane type demister, which was then validated using the experimental data. We have generated additional supplementary data in order to develop a dimensionless curve to calculate the correction factor for the Souders-Brown and Burkholz correlations for field operations. This factor can be used to predict the performance of a vane-type demister under various operational conditions. [Received: May 1, 2024; Accepted: August 7, 2024]
