A sorbent composition and process of making sorbent designed for the removal of contaminants from flue gas and subsequent use in cement or concrete formulations are discussed. The sorbent composition comprises a coal feed stock prepared to have a total BET surface area of at least 350 m/g, and wherein the sorbent has a cumulative surface area less than 10 m/g for pore diameters between 0.01 and 0.1 microns, a cumulative pore volume less than 0.055 cc/g for pore diameters between 0.01 and 0.1 microns, or both.

Inherently concrete-compatible carbon sorbents for mercury removal from flue gas

Methods and systems for reducing mercury emissions are provided herein. The methods, generally, include the steps of burning a heavy metal containing fuel source and introducing sorbent materials and introducing one or more halogen compounds into the combustion chamber and/or exhaust stream to remove the heavy metal.

Methods for removal of mercury from flue gas

A flue gas adsorbent and method for making an adsorbent for mercury capture are disclosed. The adsorbent comprises an admixture of an adsorptive material and an additive that have been physically combined thereby eliminating the need for traditional impregnation. A method for removing mercury from a flue gas stream is also disclosed.

Enhanced adsorbents and methods for mercury removal

Methods and systems for reducing mercury emissions from fluid streams are provided herein. In embodiments, mercury is removed from flue gas streams by injecting a dry admixture of a porous mercury adsorptive material and at least one halide containing agent into the flue gas stream.

Sorbent formulation for removal of mercury from flue gas

Methods and systems for reducing mercury emissions from fluid streams having a high concentration of sulfur oxide species are provided herein. In embodiments, mercury is removed from flue gas streams by injecting a dry admixture of a porous mercury adsorptive material and at least one dry agent into the flue gas stream.

An odor removal system and device are provided for removing odors from standard gravity fed and water pressure operated toilets. The system includes a fan assembly for directing air from the toilet bowl and overflow tube through a filter containing an appropriate filter material. It operates upon instruction from a mechanism designed to determine when the toilet is in use.

Odor removal system

Methods and systems for reducing mercury emissions from fluid streams having a high concentration of sulfur oxide species are provided herein. In embodiments, mercury is removed from flue gas streams containing sulfur trioxide (SO) by injecting a dry admixture of a porous mercury adsorptive material and at least one dry agent into the flue gas stream.
