Gas Absorption Column

Model HV-EXP1735
Gas Absorption Column This apparatus is used to determine the air pressure differential across the column as a function of air flow rate at different water flow rates down the column, and flooding point can be noted..          Absorption process of carbon dioxide from air-CO2 mixture into caustic soda solution, is also studied using this system. 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.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. 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.     Chemical Engineering Laboratory lab equipment manufacturers,exporters and Chemical Engineering Laboratory Lab suppliers
