DA towers are an essential part of the Water injection system. Their purpose is to remove Oxygen, thus inhibiting corrosion and microbial growth, used in conjunction with Oxygen Scavenger and Biocide chemicals.
Depending on the asset, eitger PW or SW can be used for injection. The EP had potential to use either/or, obviously dependent on the amount of injection water required and PW from the wells.
