The petroleum industry has recently shown interest in the development of in
novative alternatives to the conventional vessel-type separator. One such a
lternative is the gas-liquid cylindrical cyclone (GLCC) separator,,which is
simple, compact, and low weight, and has low capital and operational costs
. A new mechanistic model is proposed, for the first time, to predict the a
spect ratio of the GLCC, based on its complex hydrodynamic multiphase flow
behavior This model incorporates an analytical solution for the gas-liquid
vortex interface shape, and a unified particle trajectory model for bubbles
and droplets. A simplified GLCC design methodology, based on the foregoing
mechanistic model, is developed and specific design criteria are proposed
as user guidelines for GLCC design. A summary of four actual field applicat
ion designs is provided to demonstrate the capability of the aspect ratio m
odeling and the impact that the GLCC technology may have on the petroleum i
ndustry.
