Patent ID: 8671870

Claim:
A system for removing and processing a gas from a submerged area, comprising: a membrane disposed over at least a portion of the submerged area and at least partially enclosing a gas volume, the membrane having an extraction port; an extraction conduit having first and second portions, the first portion being in fluid communication with the gas volume via the extraction port; a first chemical reactor coupled to the second portion of the extraction conduit to receive gas from the gas volume, the first chemical reactor having a first reaction zone positioned to conduct a first non-combustion reaction to dissociate a donor substance of the gas; a second chemical reactor coupled to the extraction conduit second portion, the second chemical reactor having a reaction zone positioned to conduct a second non-combustion dissociation reaction different than the first reaction; and a valve disposed between the extraction conduit second portion and the chemical reactors to route gas having a first composition to the first reactor and gas having a second composition different than the first to the second reactor.
