Carbon Dioxide Medium Pumps

There are many solutions that can remove CO2 from process gas, some of which operate close to the vapor pressure of the liquid. Following figure shows one way to solve this problem.

The use of multiple nozzles reduces the changes in direction in the suction line. Extending the nozzles to a maximum distance before exiting the skirt above headroom and adding a slight slope to the horizontal run also helps streamline the piping.

The suction strainer must be located away from the pump, as shown in the vertical portion of the line, and placed low enough to maintain.

Once again, early planning by the plant layout designer allows this additional nozzle feature to be added to the quote documents.
