Gas volume release

  1. Hi I'm trying to work out what the volume of gas would be at atmospheric pressure if it is released from a pipeline under pressure (168Barg)
    The gas is hydrocarbons with unknown chemistry.

    You know vol of gas because it will be vol of pipeline (Vinitial) so could you do:

    vfinal = Vinitial x (Pinitial + Patmospheric) / (Pfinal +Patmospheric)

    But I'm not sure this accounts for compressibility correctly?

    Let me know
