    Abstract: A pressure vessel refuelling system enables fast refuelling of Compressed Natural Gas (CNG) fuel tanks. The system includes a pressure vessel having a gas inlet/outlet port and a liquid inlet/outlet port; a first liquid at least partially filling the pressure vessel; a liquid layer of a second liquid floating on top of the first liquid, wherein the second liquid is immiscible with the first liquid; a gas at least partially filling the pressure vessel above the liquid layer of the second liquid, the gas in fluid communication with the gas inlet/outlet; and a pump in fluid communication with the liquid inlet/outlet of the pressure vessel, whereby the first liquid can be pumped or returned to/from storage into or out of the pressure vessel.

    Abstract: A catalytic tank heater includes a catalytic heating element supported on an LPG tank by a support structure that holds the element in a position facing the tank. Vapor from the tank is provided as fuel to the heating element, and is regulated to increase heat output as tank pressure drops. The heating element is internally separated into a pilot heater and a main heater, with respective separate fuel inlets. The pilot heater remains in continual operation, but the main heater is operated only while tank pressure is below a threshold. Operation of the pilot heater keeps a portion of the catalyst hot, so that, when tank pressure drops below the threshold, and fuel is supplied to the main heater, catalytic combustion quickly expands from the area surrounding the pilot heater to the remainder of the catalyst.

    Abstract translation: 催化罐加热器包括通过支撑结构支撑在LPG罐上的催化加热元件,该支撑结构将元件保持在面向油箱的位置。 来自罐的蒸汽作为加热元件的燃料提供,并且随着罐压力下降而被调节以增加热量输出。 加热元件在内部分为先导加热器和主加热器,分别具有各自的燃料入口。 先导加热器保持连续运行,但主加热器仅在油箱压力低于阀值时运行。 先导加热器的操作保持催化剂的一部分热,使得当罐压力下降到阈值以下并且向主加热器供应燃料时,催化燃烧从先导加热器周围的区域迅速膨胀到催化剂的其余部分 。
