【Activated carbon has been successfully used in numerous gas processing applications for many years. Activated carbon's highly porous nature and large surface area make it an ideal adsorbent for removing trace contaminants from liquid and gaseous streams. For some inorganic contaminants encountered in gas processing operations, removal can be enhanced by impregnation of the activated carbon to promote both physical adsorption and chemisorption.】

【AC is a black, solid substance resembling granular or
powdered charcoal. It is extremely porous with a very large
surface area. One ounce of AC has an estimated 30,000 square
yards of surface area. Certain contaminants accumulate on the
surface of the AC. This is called adsorption. The two main
reasons that chemicals adsorb onto AC is 1) a "dislike" of the
water and 2) attraction to the AC. Adsorption of most
contaminants results from a combination of 1 and 2. Many organic compound
