Droplet entrainment was investigated in the feed section of distillation columns for multiple feed inlet devices under different flow conditions. Entrainments from two-phase flow regimes were measured in the feed section of a column with an air and water system. A new feed inlet device named demister flash box was developed. Measurements with two-phase flow regime in the feed pipe indicated that the demister flash box had the lowest entrainment. Experiments with a surfactant in water due to low surface tension demonstrated that the entrainment was higher compared to water. In addition, entrainment determinations with high droplet flow rate from a spray nozzle in feed were conducted. The results indicated that the V baffle had the lowest entrainment.
