Abstract: Method for removal of oxygen from seawater includes leading a stream of seawater and a pressurized stripping gas to a first mixer, mixing the seawater with stripping gas, leading the combined stream to a first gas/liquid inline separator, separating the stream into a liquid rich and a gas rich phase, leading the liquid stream and a stripping gas stream to a second mixer, mixing the liquid stream with the gas stream, leading the combined stream to a second stage inline separator, separating the combined stream into a liquid- and gas-rich phases, mixing the gas stream with a fresh water stream, leading this combined stream to a first stage scrubber, removing a portion of the salt entrained in the combined stream from the scrubber, and leading the salt depleted gas stream from the first scrubber via a heat exchanger or electrical preheater together with a fuel stream to a catalytic deoxidizer.

Abstract: Present invention relates to a method for removal of oxygen from seawater comprising the following steps: lead a stream of seawater (1) to be treated and a pressurized stripping gas (2) to a first mixer (3) and mix the seawater (1) with stripping gas (2); lead the combined stream (4) of seawater (1) and stripping gas (2) to a first gas/liquid inline separator (5) and separate the stream (4) into a liquid rich (6) and a gas rich (1 1) phase; lead the liquid stream (6) and a stripping gas stream (7) containing CO2 and water to a second mixer (8) and mix the liquid stream (6) with the gas stream (7); lead the combined stream (9) from the second mixer (8) to a second stage gas/liquid inline separator (10) and separate the combined stream into a liquid rich (14) and a gas rich phase (15); mix the gas stream (1 1) from the first gas/liquid separator (5) with a fresh water stream (22) and lead this combined stream to a first stage scrubber (12) and remove a major portion of the salt entrained in the combined stream
