The actual diameter chosen depends on a trade-off between smaller, more economic diameters, and the larger diameters needed to prevent re-entrainment of previously separated liquid droplets that can break away from the gas-liquid interface. The lower diameter limit has been previously determined by design guidelines based on the slenderness ratio of the vessel. This article presents a procedure for determining the lower diameter limit and for calculating the maximum gas capacity of a horizontal separator based on liquid re-entrainment. The method is based on correlations for predicting the onset of liquid re-entrainment developed previously by Ishii and GroImes. The procedure uses known and predicted liquid and gas properties and may be used in conjunction with normal design procedures for more economic horizontal separator designs.
