Abstract
A method for treating a gas stream containing an acid gas, including immersing a permeable membrane having a plurality of pores in an absorption liquid containing a reactant chemical, and passing the gas stream through the pores in the permeable membrane so that the gas stream forms gas bubbles which float up through the absorption liquid and so that the acid gas in the gas stream reacts with the reactant chemical in the absorption liquid, thereby separating the acid gas from the gas stream. A gas absorption apparatus, including a housing adapted to hold an absorption liquid containing a reactant chemical, and a permeable membrane having a plurality of pores contained within the housing and adapted to be immersed in the absorption liquid.
