Abstract
A sorbent composition for removing mercury from flue gas, including a powdered sorbent having a fifty percent distribution particle size of from about 20 micrometers to about 75 micrometers. The invention also include a method of cleaning flue gas, the method including injecting a powdered sorbent into the flue gas, wherein the powdered sorbent has a fifty percent distribution particle size of from about 20 micrometers to about 75 micrometers.
Claims14
A sorbent composition for removing mercury from flue gas, comprising:
- a powdered sorbent having a fifty percent distribution particle size of from about 25 micrometers to about 75 micrometers,
- wherein said sorbent composition does not contain halogen and said powdered sorbent improves mercury removal from flue gas without halogen.
A method of cleaning flue gas, the method comprising:
- injecting a powdered sorbent into the flue gas, wherein the powdered sorbent has a fifty percent distribution particle size of from about 25 micrometers to about 75 micrometers, wherein said powdered sorbent does not contain halogen and said powdered sorbent improves mercury removal from flue gas without halogen;
- collecting the powdered sorbent in a flue gas desulfurization system;
- and
- removing the powdered sorbent from a dewatered slurry in a flue gas desulfurization system using a hydrocyclone in communication with the flue gas desulfurization system.
A method of cleaning flue gas, the method comprising:
- injecting a powdered sorbent into the liquor/slurry of a flue gas desulfurization system, wherein the powdered sorbent has a fifty percent distribution particle size of from about 20 micrometers to about 75 micrometers.
