CO2 pump

CO2 pumpIt is a specialized pump used for compressing, transporting gaseous, liquid or supercritical carbon dioxide. It is not only the "cooling heart" of refrigeration and air conditioning, but also the "green artery" of carbon capture systems, and the "energy engine" of supercritical power generation. In today's booming development of carbon neutrality and environmental protection technologies, this type of pump is integrating into every corner of human industrial civilization with special value.

core functionality

1. Phase control: Accurately maintain the CO ₂ phase state to avoid cavitation or liquid hammer caused by gas-liquid two-phase flow.

2. High pressure sealing: prevents greenhouse gas leakage (the greenhouse effect of CO ₂ escape is 25 times that of CO ₂).

3. Efficient transmission: spanning temperature ranges from -50 ℃ to 700 ℃, suitable for carbon neutrality in multiple scenarios.

CO2 pumpApplication scenarios

1. Transcritical refrigeration system

CO ₂ refrigerant: CO ₂ pump for supermarket cold chain, GWP=1 (traditional Freon GWP>4000).

2. Carbon Capture and Storage (CCS)

Flue gas treatment: CO ₂ in the power plant flue gas is compressed by a pump to a supercritical state and injected into underground rock formations.

3. Supercritical power generation

SCO ₂ Brayton cycle: The pump pressurizes sCO ₂ to 25MPa to drive the turbine, with a power generation efficiency greater than 50%.

4. Food industry

Beer carbonation: The liquid CO ₂ pump precisely controls the bubble density (accuracy ± 0.1g/L).

Dry ice manufacturing: A high-pressure pump expands liquid CO ₂ to -78.5 ℃ dry ice for cold chain transportation.
