Abstract
A method of chemically treating an acid gas, includes the steps of immersing a micro-porous membrane having a plurality of micro-pores in a liquid containing a reactant chemical and passing a gas stream containing an acid gas under pressure through the micro-porous membrane. The acid gas passes through the micro-pores to form micro-bubbles which float up through the liquid and react with the reactant chemical. A number of configurations of gas absorption columns are described as being suitable for use in accordance with the teachings of this method.
