1. A method of storing and delivering a fluid, comprising:

  • storing the fluid in its liquid state in a pressure vessel located at a site remote from a processing facility;

    delivering the fluid in its liquid state under a first predetermined pressure to an evaporator vessel located at the processing facility;

    maintaining the evaporator vessel substantially at a first predetermined temperature above an ambient temperature range, such that the fluid at such first predetermined temperature and first predetermined pressure is substantially always in a gaseous state, thereby evaporating the fluid entering the evaporator vessel and maintaining in the evaporator vessel a supply of the fluid in its gaseous state at such first predetermined pressure;

    drawing fluid from the supply of fluid in the evaporator vessel for use within the processing facility;

    reducing the pressure of such drawn off fluid to a second predetermined pressure of such magnitude at which the fluid retains its gaseous state at a temperature in a range expected to be maintained within the processing facility; and

    delivering the fluid at substantially such second predetermined pressure to a usage destination within the processing facility.
