  • Hydrocarbon gas flow rate adjusting method and apparatus
    Publication number: 20060003280
    Abstract: An object of the present invention is to provide a hydrocarbon gas flow rate adjusting method and apparatus, which suppress deterioration of an elastic foamed body with the passage of time and enables a stabilized adjustment of the flow rate for a long period by combining a fine porous film with a porous elastic foamed body. More specifically, fuel gas taken out of a tank which stores hydrocarbon fuel gas in liquid phase is controlled in its flow rate such that the upper limit of the flow rate is the maximum flow rate obtained by depressurizing the fuel gas with a flow rate restricting member as a first stage and then adjusting to an arbitrary flow rate within a range of the restricted maximum flow rate with an adjustable flow rate adjusting member.
