Abstract
A system for treating a contaminated gas stream is provided that includes a comminution device 204 operable to effect size reduction of a plurality of sorbent particles and form a plurality of comminuted particles, a plurality of nozzles 224 distributed through the gas stream and operable to introduce the plurality of comminuted particles into the gas stream, and a particle removal device 104 operable to remove at least most of the introduced comminuted particles and form a treated gas stream. The comminution device is in direct fluid communication with the nozzles.
Claims28
A method, comprising:
- (a) receiving, at a site of end use and from a manufacturer at a remote location, a free-flowing, particulate sorbent, the particulate sorbent particles having a first size distribution when received on site;
- (b) introducing the particulate sorbent into a chamber of an agitated media attrition mill, the agitated media attrition mill being located on site;
- (c) while in the chamber, reducing the sizes of the introduced particulate sorbent by inter-particle collisions to produce milled sorbent particles having a second size distribution, wherein the second size distribution is smaller than the first size distribution, and wherein a desired particle size of the milled sorbent particles is a size of less than about 15 microns;
- and
- (d) thereafter introducing, on site, the milled sorbent particles into a contaminated flue gas stream to remove one or more contaminants.
A method, comprising:
- receiving, at a site of end use of the sorbent and from a manufacturer at a remote location, a free-flowing, particulate sorbent, the particulate sorbent having a first size distribution when received on site;
- contacting the particulate sorbent with a pressurized fluid jet configured to effect comminution of the particulate sorbent to form a comminuted fluid stream;
- contacting, on site, the comminuted fluid stream with a collider positioned in a path of the comminuted fluid stream to further comminute the particulate sorbent;
- discharging, on site, comminuted particulate sorbent, wherein a second size distribution of the discharged, comminuted particulate sorbent is smaller than the first size distribution, and wherein the discharged, comminuted particulate sorbent has a size of less than about 15 microns;
- and
- thereafter introducing, on site, the discharged, comminuted particulate sorbent into a contaminated flue gas stream to remove one or more contaminants, the contaminated flue gas stream being from an industrial plant, wherein the industrial plant is located on site.
