APPARATUS FOR EMISSIONS REDUCTION AS A SERVICE (ERaaS)
STAXLINK™ is a duct system and method for conveying exhaust gas from an exhaust pipe of an emissions source to a purification unit during an Emissions Reduction as a Service (ERaaS) operation. Example emissions sources include oceangoing vessels and buildings structures. The duct is temporarily installed onto the emissions source without a crane. The duct is supported by the emissions source itself for the duration of the ERaaS operation.
1 . A system for reducing or removing impurities from exhaust gases, the system comprising:
a purification unit having an inlet port for receiving exhaust gases for purification and an outlet port for outputting gases in which impurities have been reduced or removed; and
a cascading ducting system comprising a plurality of duct sections, wherein a first duct section of the plurality of duct sections comprises a pivot assembly configured to interface with a second duct section of the plurality of duct sections, the cascading ducting system configured to interface with an exhaust pipe of an emissions source to receive exhaust gases emitted therefrom.
2 . The system of claim 1 , wherein one or more of the plurality of duct sections comprises:
an exoskeleton defining an interior volume.
3 . The system of claim 2 , wherein one or more of the plurality of duct sections comprises:
an insulated panel supported by the exoskeleton.
4 . The system of claim 1 , wherein each of the plurality of duct sections weighs less than 50 pounds.
5 . The system of claim 1 , wherein the impurities reduced or removed are selected from the group comprising:
particulate matter;
oxides of nitrogen;
oxides of sulfur; and
carbon dioxide.
6 . The system of claim 1 , wherein each pivot assembly comprises:
a pivot;
a pivot plate; and
pivot guides.
7 . The system of claim 1 , wherein the emissions source is an oceangoing vessel structure comprising a vessel deck.
8 . The system of claim 7 , wherein the purification unit is positioned on the vessel deck.
9 . The system of claim 7 , wherein the purification unit is positioned external to the oceangoing vessel structure.
10 . A duct system configured to convey exhaust gas from an exhaust pipe of an emissions source to a purification unit during an emissions reduction operation, the duct system comprising:

11 . The duct system of claim 10 , wherein one or more of the plurality of duct sections comprises:
an exoskeleton defining an interior volume.
12 . The duct system of claim 11 , wherein one or more of the plurality of duct sections comprises:
an insulated panel supported by the exoskeleton.
13 . The duct system of claim 10 , wherein each of the plurality of duct sections weighs less than 50 pounds.
14 . The duct system of claim 10 , wherein impurities reduced or removed are selected from the group comprising:
particulate matter;
oxides of nitrogen;
oxides of sulfur; and
carbon dioxide.
15 . The duct system of claim 10 , wherein each pivot assembly comprises:
a pivot;
a pivot plate; and
pivot guides.
16 . The duct system of claim 10 , wherein the emissions source is an oceangoing vessel structure comprising a vessel deck.
17 . The duct system of claim 16 , wherein the purification unit is positioned on the vessel deck.
18 . The duct system of claim 16 , wherein the purification unit is positioned external to the oceangoing vessel structure.
