Vacuum deaeration to remove oxygen from waterflood water may be an economical alternative to the more conventional gas stripping or chemical scavenging methods. Where chemical costs are high, in remote areas where chemical transportation is expensive, or where acceptable stripping gas is not available, vacuum deaeration can help waterflood operators arrest corrosion of bare steel pipe and prevent detrimental bacteria growth. The compression cost for recovery of low pressure stripping gas may also be of concern even when acceptable natural gas is available. Some guide lines are given for the design of single pressure, multiple pressure, and vacuum plus stripping gas systems. It is shown how to make equilibrium calculations. Of the mechanical vacuum pumps available, the liquid ring type is probably best suited to deaeration applications, due to its reliability and ability to accept free water carryover. A typical flow diagram of a system using a liquid ring type vacuum pump is illustrated.
