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.

The present disclosure relates to methods for producing metal sulfide disposed on particle substrates. In at least one embodiment, a method for producing an alkali earth hydroxide particle having a metal sulfide disposed thereon includes introducing an alkali earth oxide particle with a metal sulfate to form a first composition. The method includes introducing an alkali sulfide or an alkali earth sulfide with the first composition to form a second composition. The present disclosure further relates to compositions of matter having metal sulfide disposed on a particle substrate. In at least one embodiment, a composition of matter includes an alkali earth hydroxide particle. The composition of matter includes a metal sulfide disposed on the alkali earth hydroxide particle.

The present disclosure provides systems for carbon capture in combination with production of one or more industrially useful materials. The disclosure also provides methods for carrying out carbon capture in combination with an industrial process. In particular, carbon capture can include carrying out calcination in a reactor, separation of carbon dioxide rich flue gases from industrially useful products, and capture of at least a portion of the carbon dioxide for sequestration of other use, such as enhanced oil recovery.

A regenerator vessel for adsorbing halogen-containing material from a regenerator vent gas stream has a plurality of catalyst nozzles disposed at a top portion of the regenerator vessel. A first gas outlet is associated with a chlorination zone, and a second gas outlet associated with a combustion zone. A drying zone is in fluid communication with an air heater and the drying zone located in a bottom portion of the regenerator vessel. The first gas outlet is configured to withdraw a first gas stream from the chlorination zone and the second gas outlet is configured to withdraw a second gas stream from the combustion zone. The top portion of the regenerator vessel has an adsorption zone having a vent gas inlet port, a vent gas outlet port, and a portion of an annular catalyst bed.

A contaminated gas stream can be passed through an in-line mixing device, positioned in a duct containing the contaminated gas stream, to form a turbulent contaminated gas stream. One or more of the following is true: (a) a width of the in-line mixing device is no more than about 75% of a width of the duct at the position of the in-line mixing device; (b) a height of the in-line mixing device is no more than about 75% of a height of the duct at the position of the in-line mixing device; and (c) a cross-sectional area of the mixing device normal to a direction of gas flow is no more than about 75% of a cross-sectional area of the duct at the position of the in-line mixing device. An additive can be introduced into the contaminated gas stream to cause the removal of the contaminant by a particulate control device.
