摘要： A system and method for removing contaminants from emissions including the use of a matrix for selecting application specific copper, zinc, tin, sulfide (CZTS) sorbent compounds. The CZTS sorbent compound is a reactive material that removes contaminates from gaseous and/or non-gaseous emissions. The CZTS sorbent compound becomes a broad-spectrum reactive material with enhanced properties when alloyed specifically with precise elements targeting specified contaminates present in application specific emissions. The matrix disclosed herein defines which enhancement element is best suited for application specific compounding. The method may include testing the contaminated emissions and then routing the emissions through one or more specific filters based on pairing contaminates with filters containing corresponding CZTS sorbent compounds.

摘要： A system for removing contaminants from emissions including a reverse venturi shaped fluidized bed device featuring a method for tilting and/or agitation. The system includes numerous component devices such as, but not limited to, an influent source, a fluidized bed device, a post filter device, and an effluent discharge, each of which are able to be isolated, integrated, bypassed, and/or reconfigured for application specific emissions requirements. The filter media is a mass of reactive material disposed within the fluidized bed which is in intimate contact with the emissions as they pass through the fluidized bed. The mass of reactive material contains an amalgam forming metal which chemically binds with the emissions that are passing through the system. Methods for removing contaminants from gaseous and non-gaseous emissions are also provided.

摘要： A system and method for cleaning, conditioning, and/or rejuvenating carbon-based sorbents is disclosed where a chemical cleaning process is used to separate contaminants from the sorbent. The contaminants can be disposed of or recycled for industrial uses. The cleaned and/or rejuvenated carbon-based sorbent is recycled back into a reverse venturi shaped fluidized bed apparatus for later use. Spent carbon-based sorbent can be routed for appropriate disposal. The carbon-based sorbents include, but are not limited to, activated carbon sorbent and biochar sorbent. Optionally, the sorbents can be processed through the system prior to exposure to contaminated emissions to enhance and increase the porosity of the outer surface of the sorbents.

摘要： An apparatus for removing contaminants from emissions is provided with a reverse venturi shaped fluidized bed device integrated into the system. The system includes numerous component devices such as, but not limited to, an influent source, a fluidized bed device, a post filter device, and an effluent discharge. The system may also include one or more application specific pre-filter and/or post filter devices. The fluidized bed is constructed with a specific length to diameter ratio for optimum restrictive flow through a specialized filter media. The filter media is a mass of reactive material disposed within the fluidized bed which is in intimate contact with the emissions, as the emissions pass through the fluidized bed. The mass of reactive material contains an amalgam forming metal which chemically binds with the emissions that are passing through the system. Methods for removing contaminants from gaseous and non-gaseous emissions are also provided.

摘要： An apparatus for removing contaminants from emissions is provided with a housing shaped as a reverse venturi. The housing includes an entry portion for receiving emissions, an exit portion for expelling emissions, and an enlarged portion disposed therebetween for trapping the contaminants in the emissions. A mass of reactive material is disposed within the enlarged portion and has a reactive outer surface disposed in contact with the emissions. The mass of reactive material contains an amalgam forming metal at the reactive outer surface that chemically binds with the emissions that are passing through the enlarged portion of the housing. Emissions control methods for removing contaminants from gaseous and non-gaseous emissions are also provided. One of the emissions control methods includes passing the gaseous emissions through the reverse venturi apparatus described herein. Another one of the emissions control methods includes treating non-gaseous emissions in a treatment tank containing a sorbent.
