Abstract

Parallel modules for in-line recharging of sorbent materials using alternate duty cycles for a sorbent cartridge. The sorbent cartridge can have two or more modules contained therein having connectors connecting each of the modules. One or more of the modules can be reusable and the sorbent materials therein can be recharged.

Claims

1. A method of recharging a sorbent, comprising the steps of:

connecting at least a first module and a second module in parallel with one or more connectors;

fluidly connecting at least one connector to at least one wash line, wherein the at least one wash line is fluidly connected to a recharger;

fluidly connecting at least one connector to at least one bypass line, wherein the at least one bypass line diverts flow from the connector to bypass at least one module;

connecting one or more valves to the connectors at junctions between the modules, the at least one bypass line and/or the at least one wash line; and

selectively opening and closing the valves to direct fluid flow from the recharger through the at least one of the first module and second module to recharge a sorbent in the first module or second module.

2. The method of claim 1, wherein the one or more valves are any one of a two-way, three-way, four-way valve or combinations thereof.

3. The method of claim 1, wherein a valve is positioned on a connector before the first module, the valve connecting the connector, a wash line and the second module, wherein the valve is open to the wash line, and closed to the connector and second module such that flow is directed to a recharger.

4. The method of claim 1, wherein a valve is positioned on a connector before the first module, the valve connecting the connector, a wash line and the second module, wherein the valve is open to the wash line and connector, and closed to the second module such that flow is directed to a recharger.

5. The method of claim 1, wherein a valve is positioned on a connector before the first module, the valve connecting the connector, a wash line and the second module, wherein the valve is open to the second module, and closed to the wash line and the connector, such that flow is directed to the second module.

6. The method of claim 1, wherein a valve is positioned on a connector before the first module, the valve connecting the connector, a wash line and the second module, wherein the valve is open to the connector, and closed to the second module and the wash line, such that flow is directed through the connector and through the first module.

7. The method of claim 1, wherein a pump is attached to the recharger or the at least one wash line.

8. The method of claim 1, further comprising the step of using gas to blow out the module.

9. The method of claim 1, wherein the at least one wash line is subdivided into a top and bottom line.

10. The method of claim 9, wherein the top line is a liquid line and the bottom line is a gas line.

11. The method of claim 9, wherein the top line is a gas line and the bottom line is a liquid line.

12. The method of claim 9, wherein both the top line and the bottom line are liquid lines.
