Definitions

  • the present invention relates to the field of natural gas systems for vehicles and in particular to liquefied natural gas systems according to the one disclosed on DE102012024717 , the features of which constitute the preamble of claim 1.
  • a tank adapted to store LNG tends to release towards the atmosphere a certain amount of gas which depends on the pressure and temperature of the gas in the tank. In general it is estimated that after about 180h the first releases of gases to the outside occur.
  • Such gas contributes to the calculation of the emissions of a vehicle, since natural gas is a greenhouse gas similar to carbon dioxide.
  • the purpose of the present invention is to reduce the overall emissions of a vehicle fuelled with liquefied natural gas.
  • the basic idea of the present invention is to recover the natural gas released from the liquefied natural gas tank and to store it in another appropriate tank.
  • this appropriate tank is a high pressure tank for compressed natural gas.
  • a first conventional tank for liquefied natural gas is joined by a second tank for compressed natural gas.
  • a pressure sensor is present in the first tank and when it measures a pressure higher than a predefined threshold, a processing unit orders the activation of a compressor having an inlet communicating with the first tank and an outlet communicating with the second tank, in order to remove the excess gas from the first tank and compress it in the second tank.
  • the first tank comprises a safety valve calibrated at a pressure greater than the activation pressure of the aforesaid predefined pressure threshold, so that, in case of malfunction of any component of the recovery system, the excess gas can be released into the environment without any risk.
  • a check valve or a solenoid valve controlled by the processing unit is housed on the inlet or the outlet of the compressor.
  • the first tank is connected to the second tank through an expansion chamber and a compressor in succession.
  • the compressor therefore has an inlet in communication with the expansion chamber and an outlet in communication with the second tank.
  • the connection between the first tank and the expansion chamber is made by means of a first safety/overpressure valve which releases the excess gas of the first tank into the expansion chamber.
  • the expansion chamber contains a pressure sensor. When it measures a pressure above a predefined threshold inside the expansion chamber, a processing unit orders the activation of the compressor which withdraws the gas released in the expansion chamber and compresses it in the second tank.
  • the first tank and/or the expansion chamber comprises a second safety valve calibrated at a pressure greater than the activation pressure of the first safety/overpressure valve, so that, in case of malfunction of any component of the recovery system, the excess gas can be released into the environment without any risk.
  • This second variant compared to the first, makes it possible to do without the pressure sensor in the first tank, where temperatures are below -100°C. In addition, it makes it possible to avoid modifying a tank for liquefied natural gas, keeping it as originally conceived.
  • the recovered gas can be used to drive the vehicle resulting in a corresponding increase of total mileage, with undoubted economic and environmental advantages.
  • the present invention relates to a system for the recovery of natural gas released from a liquefied natural gas tank, as described in claim 1.
  • Another object of the present invention is a natural gas supply system comprising the aforesaid recovery system.
  • a further object of the present invention is a land vehicle fitted with an internal combustion engine powered by a liquefied natural gas fuel supply system comprising the aforesaid recovery system.
  • second component does not imply the presence of a “first” component.
  • Figure 1 shows an example not forming part of the invention but useful for its understanding, wherein a first tank 1 is of the type intended to store liquefied natural gas.
  • a first safety valve V1 places the tank 1 in communication with the environment. Generally, this valve is connected to a first opening placed in the upper part of the tank, so as to intercept only the gaseous phase.
  • a second opening H2, different from the first opening, is connected to an inlet of a compressor CP.
  • the outlet of the compressor CP is connected to a second tank 2 intended to store compressed natural gas.
  • a check valve CV is placed upstream or downstream of the compressor CP, depending on the direction of circulation of the gas aspirated from the tank 1 and introduced into the tank 2.
  • a pressure sensor P is housed in the first tank 1.
  • a CPU processing unit is connected to said pressure sensor P and when the pressure measured by it exceeds a predefined threshold, the processing unit orders the activation of the compressor which aspirates natural gas in the gaseous phase from the first tank 1 compressing it in the second tank 2.
  • said predefined threshold is appropriately below an activation threshold of the first safety valve V1.
  • Both the first tank and the second tank comprise respective openings towards the injection device of the natural gas supply system fuelling the internal vehicular combustion engine, not shown.
  • Figure 2 shows the invention in which the first and second tank are present, as in the previous example.
  • connection between the first tank is made in succession through an expansion chamber EX and the compressor CP.
  • the first tank as before, comprises a first safety valve V1 which places the tank 1 in communication with the environment.
  • the first tank comprises a second safety /overpressure valve V2 which connects the first tank with the expansion chamber EX.
  • the compressor CP has an inlet connected with the expansion chamber EX and an outlet connected with the second tank 2.
  • a check valve CV is placed between the expansion chamber EX and the compressor CP, or downstream of it, i.e. between the compressor CP and the second tank 2.
  • a pressure sensor P is housed in the expansion chamber EX.
  • a CPU processing unit is connected to said pressure sensor P and when the pressure measured by it exceeds a predefined threshold, the processing unit orders the activation of the compressor which aspirates natural gas in the gaseous phase from the expansion chamber compressing it in the second tank 2.
  • the pressure thresholds that determine both the opening of the overpressure/safety valve V2 and the activation of the compressor are appropriately below an activation threshold of the first safety valve V1.
  • the compressor CP is preferably an electro-compressor.
  • a second pressure sensor inside the second tank, so as to inhibit the activation of the electro-compressor when the pressure measured in the second tank exceeds a further predefined threshold.
  • the second tank too may be fitted with a safety valve not shown.
  • a pressure sensor is completely optional, as it is possible to estimate the excess gaseous phase in the first tank in different ways, for example on the basis of the quantity and temperature of the liquid phase present in the first tank.
  • the quantity may be determined indirectly based on the capacity of the first tank 1 based on the consumption of liquefied natural gas.
