What are the types of treatment methods for bituminous smoke?
Filtration is a method that utilizes porous media to collide with and adsorb fine tar particles from bituminous smoke, thereby purifying the smoke.
Bag filters are one of the commonly used methods.
However, for bituminous smoke purification, the filter bags need to have oil and water resistance, heat resistance, and corrosion resistance properties.
Adsorption purification method is a process that uses porous solids (adsorbent filters) to accumulate or concentrate one or multiple components of a fluid (gas or liquid) mixture on the surface, achieving the goal of separation.
Physical adsorption is caused by intermolecular forces, commonly referred to as “Van der Waals forces”.
