    摘要： Embodiments of a pressurized gas supply are provided. In one embodiment, the pressurized gas supply includes a pressurized gas reservoir and a pressure reducer fluidly coupled to the pressurized gas reservoir. The pressure reducer is configured to reduce the pressure of gas received from the pressurized gas reservoir to a predetermined output pressure (PO). A gas mixture is held within the pressurized gas reservoir at a starting pressure (PS) and at a starting temperature (TS). The gas mixture includes: (i) a warming gas having a positive Joule-Thomson (JT) coefficient at TS and over the pressure range PS-PO, and (ii) a cooling gas having a negative JT coefficient at TS and over the pressure range PS-PO. The cooling of the cooling gas at least partially offsets the warming of the warming gas when the gas mixture is expelled by the isothermal gas supply to achieve a desired gas output temperature.

    摘要： A system to prevent the formation of hydrates in a pipeline includes a heater assembly. The heater assembly has a vortex tube mounted on an outer surface of a first section of the pipeline and a compressed gas source. The vortex tube is configured to separate gas from an inlet into a hot gas pathway and a cold gas pathway. The vortex tube includes an inlet, a cold gas outlet, and a hot gas outlet. The hot gas outlet of the vortex tube is fluidly connected to an opening defined in the first section of the pipeline. The hot gas outlet is configured to flow hot gas from the vortex tube into an interior volume of the pipeline. The compressed gas source is fluidly connected to the inlet of the vortex tube.

    摘要： A vaporizer for liquefied gas, such as liquefied petroleum gas, which includes a heat exchanger and a capacity control valve for controlling the inflow of liquefied gas to the heat exchanger. The heat exchanger has an inlet to accept liquefied gas and an outlet to release superheated gas vapor. The capacity control valve has an inlet to accept the liquefied gas from a source of liquefied gas, an outlet coupled to the inlet of the heat exchanger. The capacity control valve includes a valve positioned between the inlet and outlet of the capacity control valve, and movable between fully closed and fully open positions. The capacity control valve includes a diaphragm positioned between a thermal expansion chamber with a pressure dependent on the temperature of the gas vapor in the outlet of the heat exchanger sensed by a sensing bulb, and a liquefied gas inlet chamber with the pressure dependent on the pressure of the liquefied gas being supplied to the vaporizer by the liquefied gas source. The movements of the diaphragm move the value to regulate the flow of liquefied gas to the heat exchanger.
