Rise velocities and chord lengths measured using a novel monofiber optical probe. High gas holdup conditions achieved with elevated pressure and surfactant addition. Narrow chord length distributions where 90% of the bubbles were 1.0 mm or less. Matching energy dissipation among distributor designs achieved similar gas holdups.
