... deoxygenation process systems. Seawater is injected into the system to strip the O 2 from water by means of inert nitrogen gas. In these systems, the nitrogen stripping gas is circulated in a closed loop and regenerated over a chemical catalytic reactor, where a purity of at least 99.995 % is achieved...
