Abstract

A system and method for treatment of a medium is disclosed. The system includes a plurality of separator zones and a plurality of heat transfer zones. Each of the separator zone and the heat transfer zone among the plurality of separator zones and heat transfer zones respectively, are disposed alternatively in a flow duct. Further, each separator zone includes an injector device for injecting a sorbent into the corresponding separator zone. Within the corresponding separator zone, the injected sorbent is reacted with a gaseous medium flowing in the flow duct, so as to generate a reacted gaseous medium and a reacted sorbent. Further, each heat transfer zone exchanges heat between the reacted gaseous medium fed from the corresponding separator zone and a heat transfer medium.

First claim

The invention claimed is:

1. A system comprising:
a plurality of separator zones;
a plurality of heat transfer zones, wherein each separator zone among the plurality of separator zones and each heat transfer zone among the plurality of heat transfer zones are disposed alternatively in a flow duct entirely oriented along a horizontal direction with reference to a flow of a gaseous medium, wherein each separator zone comprises an injector device for injecting a sorbent into the corresponding separator zone, for reacting the sorbent with the gaseous medium flowing through the corresponding separator zone so as to generate a reacted gaseous medium and a reacted sorbent, wherein each heat transfer zone exchanges heat between the reacted gaseous medium fed from the corresponding separator zone and a heat transfer medium;
a recirculation channel protruding outwardly from the flow duct and extending from one separator zone disposed downstream to another separator zone disposed upstream among the plurality of separator zones, for recirculating the reacted sorbent from the one separator zone to the other separator zone; and
a plurality of collector zones, wherein each collector zone among the plurality of collector zones is coupled to a downstream side of the corresponding separator zone, for receiving the reacted sorbent from the corresponding separator zone.

2. The system of claim 1 , wherein each separator zone among the plurality of separator zones, comprises an absorber zone.

3. The system of claim 2 , wherein the corresponding injector device injects the sorbent perpendicular to the flow of the gaseous medium in the corresponding absorber zone, for absorbing a portion of a component from the gaseous medium so as to generate the reacted gaseous medium and the reacted sorbent.

4. The system of claim 3 , wherein each heat transfer zone feeds the heat transfer medium perpendicular to the flow of the reacted gaseous medium for cooling the reacted gaseous medium.

5. The system of claim 1 , wherein each separator zone among the plurality of separator zones, comprises a desorber zone.

6. The system of claim 5 , wherein the corresponding injector device injects the sorbent perpendicular to the flow of the gaseous medium in the corresponding desorber zone, for desorbing a portion of a component from the sorbent so as to generate the reacted gaseous medium and the reacted sorbent.

7. The system of claim 6 , wherein each heat transfer zone feeds the heat transfer medium perpendicular to the flow of the reacted gaseous medium for heating the reacted gaseous medium.

8. The system of claim 1 , wherein each heat transfer zone exchanges heat between the reacted gaseous medium and the heat transfer medium by directly contacting the reacted gaseous medium with the heat transfer medium.

9. The system of claim 1 , wherein each heat transfer zone exchanges heat between the reacted gaseous medium and the heat transfer medium indirectly.

10. The system of claim 1 , wherein each heat transfer zone comprises a non-stick coating for preventing fouling of the heat transfer zone.

11. The system of claim 1 , wherein each heat transfer zone comprises a vibrator device for vibrating the heat transfer zone for preventing fouling of the heat transfer zone.

12. The system of claim 1 , wherein each of the mutually adjacent separator zone and the heat transfer zone are integrated.

13. The system of claim 1 , further comprising an organic rankine cycle coupled to a downstream side of each heat transfer zone, wherein the organic rankine cycle circulates a working fluid comprises the heat transfer medium.

14. The system of claim 1 , wherein length of each separator zone is designed based on at least one of a flow rate of the gaseous medium, a composition of the gaseous medium, a flow rate of the sorbent, a composition of the sorbent, size of each droplet of the sorbent injected from the injector device, and a density difference between the sorbent and the gaseous medium in the corresponding separator zone.

15. A method comprising:
directing a flow of a gaseous medium into a flow duct comprising a plurality of separator zones and a plurality of heat transfer zones, wherein the flow duct is entirely oriented along a horizontal direction with reference to the flow of the gaseous medium, wherein each separator zone among the plurality of separator zones and each heat transfer zone among the plurality of heat transfer zones are disposed alternatively in the flow duct;
injecting a sorbent into the corresponding separator zone, for reacting the sorbent with the gaseous medium flowing through the corresponding separator zone so as to generate a reacted gaseous medium and a reacted sorbent;
feeding a heat transfer medium into the corresponding heat transfer zone, for exchanging heat between the heat transfer medium and the reacted gaseous medium fed from the corresponding separator zone; and
recirculating the reacted sorbent from one separator zone disposed downstream to another separator zone disposed upstream among the plurality of separator zones via a recirculation channel, for reacting the reacted sorbent with the gaseous medium or the reacted gaseous medium flowing through the other separator zone, wherein the recirculation channel protrudes outwardly from the flow duct and extends from the one separator zone disposed downstream to the other separator zone disposed upstream; and
feeding the reacted sorbent from a corresponding separator zone among the plurality of separator zones into a corresponding collector zone among a plurality of collector zones.

16. The method of claim 15 , wherein the injecting comprises injecting the sorbent perpendicular to the flow of the gaseous medium in the corresponding separator zone.

17. The method of claim 15 , wherein the feeding comprises feeding the heat transfer medium perpendicular to the flow of the reacted gaseous medium in the corresponding heat transfer zone.

18. The method of claim 17 , wherein the exchanging further comprises contacting the heat transfer medium directly or indirectly with the reacted gaseous medium.
