Abstract


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
