PURPOSE: A storage device for compressed media and a method for fueling a vehicle are provided to implement a general method for fueling fuel gas to a vehicle by using a variable pilgrim stage scheme. CONSTITUTION: A storage device for compressed media comprises at least nine storage containers(1) and a larger container(2) in which the storage containers are arranged into four sections. The larger container and the storage container include fire protection members(3). The storage containers are made of carbon fiber materials.

A system and a method for how to use gas are provided to lower the temperature of the gas expanded through a bypass by passing through a cooler and to compress hydrocarbon gas by passing through a compressor under -30‹C. A system and a method for how to use comprise a compressor(7) compressing gas into the compressed gas(4) and having an intake unit(6); and a line structure(5) passing the gas through the intake unit of the compressor and flowing the compressed gas from the compressor to a compressing apparatus so as to use. The line structure is composed of a bypass(9) passing the compressed gas through the intake unit of the compressor again; and an expander(12) installed in the bypass in order to re-cool the compressed gas through the bypass. The gas is hydrocarbon gas. The gas passing the intake unit of the compressor has the temperature of the intake unit. The line structure has a cooler(8) on the compressing unit(10) of the compressor so as to cool the compressed gas at the temperature higher than the temperature of the intake unit. The bypass is connected to the line structure behind the cooler in the flowing direction.

A fuel filling apparatus is provided. The fuel filling apparatus comprises an overfilling protective valve arranged in a fuel gas supply path for supplying a fuel gas to an automobile. The overfilling protective valve further comprises a fuel gas path, a valve unit for opening and closing the fuel gas path by a valve body, a valve body displacement means for displacing the valve body according to a filling pressure of the fuel gas, and a temperature modulating unit for modulating a temperature of the valve body displacement means. Even though a difference between the temperature of the fuel gas and the operation temperature of the overfilling protective valve is large, the temperature of the valve body displacement means can be maintained within the preset temperature range by the temperature modulating unit and the overfilling protective valve can be exactly operated under the preset pressure.
摘要:
A method for generating power from the vaporization of a liguefied natural gas at least partially liguefying a multicomponent mixt. of the duct (107) with the gas, pumping the mixt. in the pump (111) to an elevated pressure, heating the pressurized mixt. in the heat- exchanger (102) to form a vapor, enpanding the vapor through the first and second expanders (122, 125) and producing power from the generator (126). The mixt. comprises methane, ethylene, propane and mitrogen.
