Absorption Of CO₂ In Biogas By Intermittent Bubbling Tower

The cost of alkali-containing substance was a great expenditure in treating with some waste water with carbohydrate by anaerobic biology. The fare that cost on putting alkali-containing substance was compared with the value of CH4 to estimate the economical feasibility of the anaerobic technics . Absorption CO₂ of the gas is a method to decrease the demand of alkali-containing substance. The purpose of this subject was that the content of CO₂ in the methane (about 50%) which produces by ASBR reactor reduce to 10²0% through the gas absorption equipment in order to decrease the demand of alkali containing substance .In lab-scale, circulating gas, Dixon filling made with stainless steel, bubble columns were used in this experiment. The influence of the padding quantity, the circulating flow rate and the ratio of gas to water to the general average absorption rate of CO₂, the absorptivity of CO₂, the capability of a unit of liquid on absorption of CO₂, the press of CO₂ after the reaction and the consume of power by the air pump were studied in this experiment. It was done to find the best craft condition that can decrease the quantity of CO₂ in...
