Abstract
Methods and systems for reducing mercury emissions from fluid streams are provided herein, as are adsorbent materials having high volumetric iodine numbers.
Claims15
A method for removing mercury from a flue gas comprising:
- injecting an adsorptive material into a flue gas stream wherein the adsorptive material comprises an activated carbon having a volumetric iodine number of about 500 mg/cc to about 650 mg/cc, wherein the adsorptive material has a mean particle diameter (MPD) of less than about 15 μm, wherein the volumetric iodine number is a product of the gravimetric iodine number (mg of iodine adsorbed/gram of carbon) and the apparent density of the activated carbon (grams of carbon/cc of carbon), wherein the gravimetric iodine number is determined using standard test method (ASTM) D-4607 and the apparent density is determined using (ASTM) D-2854.
