Process for the purification of flue gas
View Patent ↗A process for the purification of flue gas, comprising the step of contacting flue gas with a carbonaceous material comprising a solid carbonaceous residue of synthetic rutile production from titaniferous ores.
1. Process for the purification of flue gas, comprising the step of contacting flue gas with a carbonaceous material, comprising a solid carbonaceous residue of synthetic rutile production from production from titaniferous ores.
2. Process according to claim 1 , further comprising injecting said carbonaceous material into the flue gas to be purified.
3. Process according to claim 2 , further comprising removing said carbonaceous from the flue gas after sufficient contact time for adsorbing contaminants from the flue gas.
4. Process according to claim 3 , further comprising:
cooling flue gas to a temperature between 0 and 500° C., before contacting it with said solid carbonaceous material;
removing dioxins, furans and mercury compounds from the flue gas;
contacting said solid carbonaceous material with the flue gas in a dry state, wet state and/or in combination with lime; and
sieving, purifying, and/or grinding said carbonaceous material prior to use.
5. The process of claim 4 , wherein said flue gas originates from waste incinerators, metallurgical facilities, metal recovery facilities, power plants or cement plants.
6. Process according to claim 2 , further comprising:
cooling the flue gas to a temperature between 0 and 500° C., before contacting it with said solid carbonaceous material;
removing dioxins, furans and mercury compounds from the flue gas;
contacting said solid carbonaceous material with the flue gas in a dry state, wet state and/or in combination with lime; and
sieving, purifying, and/or grinding said carbonaceous material prior to use.
7. The process of claim 6 , wherein said flue gas originates from waste incinerators, metallurgical facilities, metal recovery facilities, power plants or cement plants.
8. Process according to claim 1 , further comprising cooling the flue to a temperature between 0 and 500° C., before contacting it with the said solid carbonaceous material.
9. Process according to claim 1 , wherein said flue gas originates from waste incinerators, the metallurgical facilities, metal recovery facilities, power plants or cement plants.
10. Process according to claim 1 , further comprising removing dioxins, furans and mercury compounds from the flue gas.
11. Process according to claim 1 , further comprising contacting said solid carbonaceous material with the flue gas in dry state, wet state and/or in combination with lime.
12. Process according to claim 1 , further comprising sieving, purifying, and/or grinding said carbonaceous material prior to use.
