Wetted Wall Gas Absorption Column
- A floor standing apparatus, used for demonstration and determination of liquid film mass transfer coefficients.
- Comprises both wetted wall column and a
deoxygenating column, a water tank, two water pumps, an air pump and an
oxygen meter with two probes.
- The wetted wall section is 900mm long, 32mm internal diameter, and made of glass.
- The deoxygenating column is 1570mm long, 26mm internal diameter, and made of clear acrylic.
- The equipment is used to study absorption of oxygen from air into deoxygenated water, specific demonstrations include:
- Calculation of liquid film mass transfer coefficient
- Variation of this coefficient with mass flow rate
Description:
- The system components are mounted within a floor standing painted steel framework.
- The
wetted wall column is a glass column with water inlet and outlet
sections and is gimbal mounted to ensure that it can be set accurately
vertical.
- The
deoxygenating column is of similar overall size to the wetted wall
column, standing vertically adjacent to it. Beside the columns is a
control console housing flow meters, pump controls and oxygen analyser.
Situated between the columns are two special housings containing the
oxygen analysis probes which monitor the oxygen content in the water
entering and leaving the absorption column. The apparatus uses water as
the working medium, contained in a storage tank at the rear of the unit.
Pumps delivering water to the deoxygenator and the absorption column
are located at the base of the unit.
