Choose the right CO2 extraction machine: CO2 emissions

When considering a CO2 extraction machine, it is important to also consider the emissions of CO2. While the process itself is relatively environmentally friendly compared to other extraction methods, there is still a need to properly manage and control the release of CO2 during the process.

One method of managing CO2 emissions is to concentrate them in an emptying pipe and lead them to outdoor emissions. This is typically done through an exhaust opening that is at least 1 meter above the roof. By doing so, the CO2 emissions are released in a controlled manner and can be safely dispersed into the environment without causing harm to people or the surrounding environment.

Diameter of the vent pipe

Another important consideration is the diameter of the vent pipe. The diameter should be at least 2 times larger than that of the high-pressure pipe. This ensures that the CO2 can be quickly and efficiently released without causing any pressure buildup that could potentially lead to leaks or other safety hazards.

High-pressure and low-pressure reducer

When CO2 transitions from a high-pressure system to a low-pressure system, a high-pressure and low-pressure reducer is needed. The material used for this reducer is generally No. 20 steel, and the high-pressure end flange is typically made from No. 35 steel. This is important to ensure that the reducer can withstand the high pressures involved in the extraction process and that it is able to safely and efficiently transition the CO2 from the high-pressure system to the low-pressure system without any leaks or other issues.

Monitor and track

In addition to these considerations, it is also important to monitor and track the emissions of CO2 during the extraction process. This can be done through various monitoring systems and tools, such as sensors and meters that can detect the amount of CO2 being released into the environment.

Final Words

Managing CO2 emissions is an important aspect of using a supercritical CO2 extraction machine. By ensuring that the emissions are properly controlled and managed, it is possible to reduce the impact of the extraction process on the environment and ensure that the process is as environmentally friendly as possible.
