One of the big enough problems in contamination of air is gas emission result of combustion of fossil fuel. This research focussed at equipments of tower column packed countercurrent, a system equipments of cleaner of air with usage of water as absorbent. Usage of tower column packed countercurrent in period of selected time can degrade water pH of absorban used. using parameter changes of pH and measurement of removal efficiency, hence will know by most optimal appliance efectivity of system performance for the absorbed of yielded gas emission from combustion. Base from research result are got that sprayer with height (H) 15 cm at countercurrent tower column packed reactor have acquirement of efficiency of removal SO2 larger ones if compared to height 25 cm and 45 cm that is equal to 96,78% at static media and 97,62% at moving media, comparison of performance of system variation of countercurrent tower column packed seen from influence of situation height of sprayer to acquirement of efficiency removal most effective SO2 is at height of sprayer 15 cm good at static media and moving media while system of single tray with moving media condition have performance of removal SO2udKeywords : Countercurrent packed column tower, SO the highestness and effective equal to 97,62%.ud2 removal.
