Components of LNG mixed refrigerants: selection mechanism and ratios?
Thread Content
The mixed refrigerants used in our factory are methane, propane, nitrogen, isopentane, and ethylene. Why were these substances chosen? Was it based on their specific properties? Could you explain that in more detail? What are the typical proportions of these components, and what factors are taken into account when determining those proportions? Thank you so much! ! !
The choice of refrigerant should be determined based on the process; there are relevant selection guidelines available for reference
It mainly utilizes the different evaporation temperatures of various media to gradually cool down, thereby reducing energy consumption.
Different media correspond to different cold zones, and the ratios are merely ranges that can be adjusted according to actual operating conditions
