Abstract
The present disclosure is directed to the introduction of an additive to a contaminated gas stream. An additive introduction system uses a compressor and carbon dioxide separator to provide a treated carrier gas for introduction of an alkaline additive to a contaminated gas stream.
Claims21
A method, comprising:
- compressing, by a compressor, a carrier gas comprising carbon dioxide to form a compressed carrier gas;
- removing, using one or more of a pressure swing, temperature swing, selective membrane, and cryogenic separator carbon dioxide removal device, at least most of the carbon dioxide from the compressed carrier gas to form a treated carrier gas;
- contacting an additive with the treated carrier gas to form an additive-containing fluid;
- and
- introducing the additive-containing fluid into a contaminated gas stream.
2 more elements
A system, comprising:
- a carrier gas treatment system to compress and remove at least most carbon dioxide from a carrier gas and form a treated carrier gas stream, wherein the carbon dioxide is removed by one or more of a pressure swing, temperature swing, selective membrane, and cryogenic separator carbon dioxide removal device;
- a mixing system to contact additive particles with the treated carrier gas stream and form an additive-containing fluid;
- and
- a delivery system to introduce the additive-containing fluid into a contaminated gas stream.
1 more element
A method, comprising:
- treating a carbon dioxide-containing carrier gas to compress the carbon dioxide-containing carrier gas and remove at least most carbon dioxide from the carbon dioxide-containing carrier gas and form a treated carrier gas, wherein the carbon dioxide is removed by one or more of a pressure swing adsorption device, a temperature swing adsorption device, a lime-free desiccant based system, a carbon dioxide selective membrane, and cryogenic carbon dioxide separator;
- contacting the treated carrier gas with an alkaline additive material to form an additive-containing fluid;
- and
- introducing the additive-containing fluid into a contaminated gas stream.
