Pipeline, Waterflood and COa Pumps 167 Figure 10-34. Bronze impregnated graphite inserts for dry running applications, metal contact exists. One approach used successfully is to install bronzeimpregnated graphite inserts into all stationary wear rings (Figure 10- 34). Rings of this type have operated with no damage during dry running tests on multi-stage pumps where dynamic deflection permitted internal contact with rotating and stationary rings. Mechanical Seals A number of solutions in the sealing of CO 2 are offered by the various seal manufacturers who in their selection process must consider the poor lubrication quality, the possibility of icing at the faces, and the typical high-suction pressure. The CO 2 pipeline pump shown in Figure 10-35 had a pumping rate of 16,000 GPM and a maximum suction pressure of 1,800 psia. In this application, double seals were chosen using a compatible buffer fluid with adequate lubrication properties.

Horsepower Considerations As liquid CO 2 is compressible, special consideration during the pump selection process must be given to horsepower requirements. Gas horsepower (GHP) and brake horsepower (BHP) should be calculated, and it is recommended that pump shaft and driver be sized to accommodate the larger of the two. Depending on the thermodynamic properties, GHP can be greater or less than BHP. To calculate GHP, it is necessary to predict the behavior of the liquid across the pump. This can be done either from interpolation of thermodynamic tables (assuming pure CO 2 ) or by computer calculations using the new equation of state for the actual composition (see Starling 1973). This method has been widely applied to predict the behavior of any mixture of hydrocarbons. While it is recommended that final pump design be based on computer calculations, preliminary
