Abstract
ENGLISH ABSTRACT: There is a lack of hydrodynamic data under supercritical conditions, in particular in systems that attempt to
isolate hydrodynamics from mass transfer. This paper presents hydrodynamic data focusing on the
characterization of flooding. Two different flooding phenomena are identified using the column overheads,
pressure drop and liquid hold-up of the system. It is further noted that the saturated fluid properties of density
and dynamic viscosity play a significant role in flooding. A density difference of less than 250 kg/m3 between
phases and a decrease in liquid viscosity causes a shift from classical gas-liquid flooding to behaviour more
analogous to that of liquid-liquid extraction columns.
