Systems and methods for deaerating seawater using a rotating packed bed device

摘要

Seawater is deaerated using a rotating packed bed device having one or more rotatable packing rings within a housing, a liquid inlet for infusing seawater into an interior region defined by the packing rings, a gas outlet for accepting gas which has passed radially inwardly through the packing rings and removing the gas from the interior region, and a liquid outlet for removing a deaerated seawater stream from the housing. A shaft coupled to a motor drives the packing rings causing the packing rings to rotate. The feed seawater stream passes radially outwardly through each of the packing rings thereby forming the deaerated seawater stream having a lower concentration of oxygen, air and/or carbon dioxide therein than the feed seawater stream and a gas stream having been removed from the feed seawater stream. The deaerated seawater stream is then injected into a hydrocarbon producing reservoir in an EOR process.
