1. A method for improving the removal of mercury from a stream containing combustion products, including:;providing a device (12) filter, wherein providing at least one layer (76) of VPTFE and;imparting at least one layer (76) of VPTFE geometric shape (48) which is capable of holding at least a portion of the accumulated particulate matter (100), and;providing at least part of the solids in the stream for storage in the device (12) filter, due to the geometrical form (48).;2. The method of claim 1, further comprising supplying reverse flow (302) through the device (12) to remove accumulated filtered solids, wherein at least one layer (76) of VPTFE retains at least a portion of the accumulated solids during supplying reverse flow (302), due to the geometrical shape (48) at least one layer of VPTFE.;3. The method of claim 1, wherein the administration is not carried out in the combustion products of the sorbent.;4. The method of claim 3, wherein the administration is not carried activated carbon as the sorbent in the combustion products.;5. The method of claim 1, comprising administering to the sorbent (202) in the combustion products to capture mercury from the combustion device (12) filtering.;6. The method of claim 5, wherein the amount administered sorbent (202) is at least 80% less than the amount of injected sorbent required to capture mercury from the corresponding amount of combustion products by at least one layer of VPTFE, but this is a geometric shape.;7. The method of claim 6, wherein the amount administered sorbent (202) is at least 90% less than the amount of injected sorbent required to capture mercury from the corresponding amount of combustion products by at least one layer of VPTFE, but this is a geometric shape.;8. The method of claim 1 comprising providing means (400) pretreatment, upstream of the device (12) filtering to remove at least a portion of the solid particles from the combustion products prior to entering a combustion device (12) filtering.;9. The system (10) for enhanced removal of mercury from a stream containing combustion products, including:;means (12) filter, comprising at least one layer (76) of VPTFE configured to obtain the geometric shape (48) enabling to retain at least a portion of the accumulated particulate matter (100), and;device (e.g., 26 and / or 200) to provide at least a portion of the solid particles in the flow for accumulation (100) in the device (12) filter, due to the geometrical form (48).;10. The system (10) according to claim 9, further comprising means for supplying a reverse flow (302) through the device (12) to remove accumulated filtered solids, and the geometric shape of at least one layer (76) capable of holding VPTFE of at least part of the accumulated particulates when applying reverse flow (302).;11. The system (10) according to claim 9, comprising no means for introducing the sorbent to the combustion products.;12. The system (10) according to claim 11, comprising no means for introducing activated carbon as the sorbent in the combustion products.;13. The system (10) according to claim 9, comprising means (400) pretreatment, located upstream of the device (12) filtering to remove at least a portion of the solids from the combustion products before the combustion products entering into the device (12) filtration.;14. The system (10) according to claim 9, comprising means (200) introducing the sorbent (202) in the combustion products to capture mercury from the combustion device (12) filtering.;15. System (10) according to claim 14, wherein the means (200) introducing the sorbent (202) provides a number of input sorbent (202) is at least 80% less than the amount of injected sorbent required to capture the appropriate amount of mercury from the products combustion by at least one layer of VPTFE which has no geometrical shape.;16. The system (10) according to claim 15, wherein the means (200) introducing the sorbent (202) provides a number of input sorbent (202) is at least 90% less than the amount of injected sorbent required to capture the appropriate amount of mercury from the products combustion by at least one layer of VPTFE which has no geometrical shape.
