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.
A floor standing apparatus, used for demonstration and determination of liquid film mass transfer coefficients.
The deoxygenating column is 1570mm long, 26mm internal diameter, and made of clear acrylic.
The wetted wall section is 900mm long, 32mm internal diameter, and made of glass.
The equipment is used to study absorption of oxygen from air into deoxygenated water, specific demonstrations include:
Calculation of liquid film mass transfer coefficient
Determination of the power law relationship
Variation of this coefficient with mass flow rate.
The column demonstration apparatus is a small scale vessel that models the operation of a gas contactor or distillation column using air and water as working fluids. Column staging internals show:
Tray columns using sieve, valve and bubble-cap trays
Packed columns using both random and structured packing
Function:
The process has manual control valves with rotameters and is intended to demonstrate contactor distillation principles with basic visual manual operation.
Gas Contactor Distillation Column Demonstrator process uses air and water to emulate column dynamics. Water is recycled; the air is vented to atmosphere.

The panel has a thin sheet metal absorber backed by riser tubes and insulating material to reduce heat loss to the rear. The collector has a purpose designed and built panel for quality and reliability. A sturdy mobile frame supports the collector. To allow users to adjust its angle, the frame has a hinge. A box with a clear cover encloses the panel, forming the collector.
It allows students to measure and find the efficiency and heat losses of a flat plate solar energy collector. This equipment shows how a flat plate solar energy collector works.
