Do liquid ammonia pipelines, which are under a pressure of 4 bar and have normal operating temperatures ranging from 27 to 40 degrees Celsius, require insulation?
Do liquid ammonia pipelines, which are under a pressure of 4 bar and have normal operating temperatures ranging from 27 to 40 degrees Celsius, require insulation? It should be kept cold
Cooling is required; the saturation temperature under this pressure condition is 4–5°, which is lower than the dew point of moisture in the air, making condensation likely to occur. The current external temperature is between 27 and 40 degrees Celsius, which is higher than the saturation temperature; as a result, the liquid ammonia in the heat transfer pipes absorbs heat and vaporizes. ,
There is a pressure of 4 kilograms inside the pipeline, so is insulation still necessary?
Is there a big difference between 4 Bar and 4 kilograms of pressure? 1 Bar ≈ 1 kilogram
