The liquid‐phase mass transfer in sprays has been measured with carbon dioxide desorption by collecting and analyzing samples of the spray. Experiments were conducted with laboratory‐ (0.009 to 0.13 L/s) and pilot‐scale (6.4 to 12.8 L/s) centrifugal hollow‐cone spray nozzles at pressure drops from 34 kPa to 138 kPa. Significant mass transfer occurred during sample collection, and a quench sampling method was developed to minimize this effect. The number of liquid‐phase transfer units (N L ) due to spray impact onto walls and liquid pools was often as much as the spray N L . Approximately 60% of the spray N L occurs in the liquid sheet before droplet formation, and the droplet region can account for less than half of the total N L of the spray.
