Abstract
A system to purge dissolved gases selectively from liquids can include a first contactor having two first contactor inlets and two first contactor outlets. The first contactor can receive liquid from a liquid source at a first inlet of the first contactor and an inert gas source at a second inlet of the first contactor, the inert gas can purge a first portion of gas from the liquid source. The first portion of purged gas exits the first contactor at a first outlet of the first contactor. The second contactor can receive input from the second outlet of the first contactor and the inert gas, the inert gas purges a second portion of the gas from the liquid source. The second portion of purged gas can exit the second contactor at a first outlet of the second contactor.
