Gas absorption is mass transfer operation where one or more species is removed from a gaseous stream by dissolution in a liquid. Packed tower with Rashchig Rings packings is used in the experiment. The main objective of the experiment is to examine the air pressure drop across the column as a function of air flow rate for different water flow rates through the column. The pressure drop is observed every 2 minutes at air flowrate of 20 LPM, 40 LPM, 60 LPM, 80 LPM, 100 LPM, 120 LPM, 140 LPM, 160 LPM and 180 LPM for water flowrate of 1 LPM, 2 LPM and 3 LPM, respectively. The experiment is ongoing for the respective water flowrate until flooding occurs. Then, the water flowrate is changed. The pressure drop increases as the air flowrate is increases. Comparing with their respective theoretical data, the pressure drop at 1 LPM and 2 LPM shows higher value but lower value at 3 LPM. The percentage error is determined at 12.50%, 33.33% and 20.00% for water flow rate of 1 LPM, 2 LPM and 3 LPM, respectively. Packing tower work efficiently at lower liquid flow rate. Low liquid flow rate enabling the absorption rate to be maximize. The objectives are successfully obtained, thus the experiment is successfully done. Turnitin : Percentage Similarity (28%)
