This Gas Absorption Unit (Model: BP 51-80G) has been designed for student laboratory experiments to provide a hands-on experience on gas absorption and desorption by means of gas-liquid contact using solvents. The unit comes complete with two packed columns, two sump tanks, two feed pumps, a pre-heater, a heat exchanger and an air pump. Instrumentation are provided for the measurement of liquid and gas flow rates, and column pressure drop. The unit will allow students to conduct experiments on the absorption of carbon dioxide into water, and also desorption of dissolved carbon dioxide from the aqueous solution. Sampling points are provided for liquid and gas analysis purposes.
