ABSTRACT:
Embodiments of the invention provide methods, systems, and apparatus for delivering gas in a liquefied state at a controlled rate. The liquefied gas may be transported in ton cylinders by placing the ton cylinder on a transportation pallet. The transportation pallet containing the ton cylinder may be placed on a heating saddle so that a surface of the cylinder is in contact with a surface of the heating saddle. Heating fluid may flow through the heating saddle, thereby heating the liquid in the cylinder through the cylinder walls. Furthermore, the vapor pressure of the gas in the cylinder may be monitored and maintained at a desired level by regulating the flow of heating fluid through the saddle. Therefore, embodiments of the invention allow the maintenance of gas flow rates in a cylinder without removing the cylinder from its transportation pallet.
