CES Wetted Wall Gas Absorption Column Didactic Equipment Vocational Education Equipment Chemical Engineering
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 in a vertical orientation. The deoxygenating column is of similar overall size to the wetted wall column, standing vertically adjacent to it. Beside the column 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. In operation, water is sparged with nitrogen in the deoxygenator before entering the top of the wetted wall column. Air is pumped by the integral diaphragm-type air pump into the base of the column. The air passes up the column, giving up the oxygen to the water. Dissolved oxygen at inlet and outlet can be measured in rapid succession. The water drains into the storage tank to be recycled to the deoxygenator.
