Selection and calculation issues for liquefied hydrocarbon unloading compressors
Thread Content
Hello, everyone! Regarding liquefied hydrocarbons such as n-butylene, how is the gas standard cubic flow rate converted to the actual liquid flow rate for unloading compressors? For example, what is the unloading flow rate at 3.0 m³/min? Conversely, if the required unloading rate for liquefied hydrocarbons is 50 m³/h, what should be the corresponding nominal flow rate of the compressor?
Calculations are based on a constant volume of the tank truck. If a discharge rate of 50 m³/h is required, then the actual exhaust volume of the compressor will be 50 m³/h. As for the conversion of inlet and outlet gas volumes, as well as their conversion to volumes under standard conditions, the ideal gas law can be used for such calculations
