ABSTRACT:
A deoxygenation process includes the steps of adding hydrazine to a liquid containing dissolved oxygen, passing the liquid through a bed of activated carbon to catalyze a reaction between the dissolved oxygen and hydrazine whereby carbon contaminants are added to the liquid, and removing the contaminants. In another embodiment, unreacted hydrazine that remains in the liquid following the catalysis is removed by passing the liquid through an ion exchange resin. In still another embodiment, an activated carbon-catalyzed deoxygenation process employing hydrazine is practiced on a mobile platform and the process further includes the steps of transporting the apparatus to a regenerating station for regeneration. The invention also includes apparatus for carrying out the process.
