Will the CO content of LNG have any impact after decarbonization? How to adjust
Thread Content
In the LNG process, when testing the gas phase components, it was found that the gas phase contained CO after decarburization, at the drying tower and in the LNG product. Are there any safety hazards? How to adjust?
Looking at the gas composition analysis at the methanation inlet and outlet, it is generally found that CO₂ exceeds the standard. The reaction temperature of the third stage is related to the gas distribution and circulating gas volume of the first and second stages.
The carbon dioxide does not exceed the standard, thank you :D
It will increase the pressure of the LNG storage tank and increase the number of pressure relief times. To solve this problem, we can only find ways to separate CO at cryogenic temperatures, such as slightly increasing the temperature of the bottom liquid, or lowering the operating pressure of the distillation tower.
