摘要:
Disclosed is a hydrogen supply apparatus which can mix an odora nt with hydrogen gas even at a low temperature and can detect t he leakage of the hydrogen gas. The apparatus comprises a gas s torage means for storing hydrogen gas therein, an odorant-addi tion means for adding an odorant to the hydrogen gas fed from t he gas storage means, and a temperature control means for contr olling the temperature of at least one of the hydrogen gas stor ed in the gas storage means, the hydrogen gas fed from the gas storage means and the odorant.
摘要:
The invention concerns a system (10) and a method for injecting liquid odorant into a natural gas pipeline (12), comprising a reservoir (14) containing odorant in liquid form, a high-pressure pump (16) linked to the reservoir, a common injection rail (20) supplied with liquid odorant by the high-pressure pump, a plurality of odorant injectors (100) supplied with pressurised liquid odorant by the common injection rail and intended to inject odorant into the gas pipeline to cause same to be sprayed into the gas pipeline, and an electronic injection pipeline (24) for controlling the injectors and the high-pressure pump.
摘要:
The invention relates to a mobile LNG regasification plant comprising a plurality of components which are compactly mounted on a platform that is pulled by a vehicle. The aforementioned components comprise a cryogenic storage tank for LNG, an atmospheric vaporizer, a relief valve for low-temperature gas, an outlet pressure regulator, an odorizing drum, a pneumatically-actuated valve, tank level and pressure transmitters, gas temperature safety thermostat and probe, and a control panel which triggers the sending of compressed air in order to supply gas, thereby closing the corresponding fluid dynamic system. The control panel is provided with telematic means such as to enable communication with the control centre responsible for supervising operation and for planning the refilling of the tank with liquid.
摘要:
An in-vehicle hydrogen storage apparatus (1) has a hydrogen gas filling passage (8) connected from a hydrogen gas filling port (6) up to the storage device (7) that stores a hydrogen gas to be supplied to a fuel cell (2), and an odorizing agent supplying device (12) that supplies an odorizing agent to hydrogen gas in at least one of the inside of the storage device (7) and the inside of the hydrogen gas filling passage (8).
摘要:
A method and a system for odorising a gas fed into a main pipe (1) leading from a distributor station to a user by means of a device (14) for injecting a liquid odorant contained inside a lapping tank (6), pressurised at the same pressure value as the pipe (1). The system is characterised in that the delivery of the liquid odorant to said injection device (14) is unaffected by the pressure of the gas inside said main pipe (1) or by the pressure inside said pressurisable tank (6).
