Advanced DGS design solution for multiphase CO₂ pump applications

Optimize CO₂ process and power cycle efficiencies with industry-leading sealing technology

Carbon dioxide (CO₂), and especially supercritical CO₂ (sCO₂), not only plays a vital role in modern industrial processes such as urea production, carbon capture and storage, and enhanced oil recovery, it is also exceptionally attractive as a working fluid in power cycle applications.

Process or power cycle efficiencies is intricately linked to the sealing technology used on equipment for moving the fluid.

Sealing CO₂ reliably with conventional mechanical seals is challenging due to the difficulty of maintaining the fluid in a phase appropriate for the seal type. Whith CO₂, the phases range from liquid, supercritical to vapor, depending on the process parameters. 

EagleBurgmann has performed extensive analysis, calculations, and testing, and developed an effective and efficient sealing solution.

This white paper focuses on describing a CO₂ multiphase seal design solution, particularly for pump applications.

The white paper will give you insights into:

• The special characteristics of CO₂ and why they can affect the safety and reliability of the seal
• The correlation and influence of CO₂ pressure, temperature and mass flow rate
• The effects of high CO₂ seal leakage
• EagleBurgmann’s CO₂ multiphase seal design for pump applications
