Abstract

This invention provides a process of removing sulfur oxides, mercury vapor, and fine particulate matters from industrial flue gases that contain such pollutants. The pollutants are removed by modules, which contain microporous adsorbent (i.e., sorbent) material that is held within a polymer matrix. The preferred polymers are fluoropolymers. The composite material that contains the microporous absorbent material held within a polymer matrix removes sulfur oxides by converting them into high concentration sulfuric acids. It also removes mercury vapor by chemically adsorbing the mercury into the matrix. It also removes fine particulate matters by surface filtration. The sulfuric acid that is produced inside the composite material is automatically expelled onto the external surfaces of the composite material and is drained into an acid reservoir together with the fine particulate matters which are washed from the external surfaces of the composite material by the constant dripping of the sulfuric acid along the external surfaces of the composite material.
