In this paper, key point for design of CO2injection pump is explained. Material selection guide line is explained firstly both for main parts and wearing parts. Consideration of corrosion and low viscosity is important. Next, pump structure is explained. Design of thrust balancing device is very important because density of CO2will vary from inlet to outlet. Critical design point is explained, when inlet condition is close to border between liquid and vapour zone. Then, influence of temperature fluctuation is explained. Next, seal and seal system suitable for CO2injection pump is explained. Supply experience of acid gas injection pump is introduced. Finally, optimum selection of turbo machines for CO2pressurizing is reported.
