Wetted Wall Gas Absorption Column

Wetted Wall Gas Absorption Column .

Specification of  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
• Determination of the power law relationship
