Declarations under Rule 4.17: as to the identity of the inventor (Rule 4.17(i)) of inventorship (Rule 4.17(iv)) (54) Title: DEVICE AND METHOD FOR REMOVAL OF POLLUTANTS FROM GAS STREAMS (57) : A filtering device is provided for filtering pollutants from a gas stream. The device includes a cartridge comprising an inner perforated passage, an outer perforated 28 jacket, one or more non-perforated ends and a sorbent bed contained between the inner 22a passage and the outer jacket; and a outer shell containing the cartridge and having a first 36 port in fluid communication with the inner perforated passage and a second port in fluid communication with the outer perforated jacket. A flowpath of the gas stream into any one of the first port or the second port, through the sorbent bed and out of the other of the first 24 port or the second port is a bidirectional flowpath. A method is further provided for filtering 18 pollutants from a gas stream. The method includes the steps of allowing the gas stream to flow into a filtering device in a first direction, the device comprising a cartridge having a sorbent bed contained therein; directing the gas stream to bend in a second direction differing from the first direction as it enters the sorbent bed; and allowing the gas stream to pass through the sorbent bed and to exit the device. 100 FIG. 1 [Continued on next page] WO 2017/181263 Al MIDEDIMOMMIDIRMEMOMMEEMIHREVOIMIE Published: with international search report (Art. 21(3)) before the expiration of the time limit for amending the claims and to be republished in the event of receipt of amendments (Rule 48.2(h))
