Abstract

A water injection process plant includes a catalytic deoxygenation unit located subsea that makes use of a reducing agent sent from topsides in liquid form. The catalyst is preferably a palladium catalyst or its equivalent. The reducing agent is an oxygen scavenger such as but not limited to hydrazine, carbohydrazide, sodium erythorbate, methyl ethyl ketoxime ('MEKO'), hydroquinone, diethylhydroxylamine ('DEHA'), formic acid (methanoic acid). A chemical umbilical can be used to deliver the reducing agent to a mixer located upstream of the deoxygenation unit, where the agent is mixed with seawater containing oxygen.
