Definitions

  • the invention relates to a device for cooling a gas and a hydrogen filling station with such a device.
  • Hydrogen refueling stations for the gaseous refueling of hydrogen-powered vehicles are based on the principle of pressure equalization between the source storage, i.e., the (pressure) storage tank(s) of the hydrogen refueling station, and the sink storage, i.e., the vehicle's fuel tank being filled.
  • the source storage is usually cascaded to ensure a sufficiently rapid hydrogen flow as the sink pressure increases, thus complying with the respective refueling standard (e.g., SAE J2601, CEP, JPEC, or similar). Due to these refueling standards, the pressure ramps must be controlled accordingly.
  • the object of the present invention is to provide a device for cooling a gas and a hydrogen filling station with such a device, which requires less equipment and process engineering effort for pre-cooling the hydrogen to be transferred, or in the best case makes this pre-cooling obsolete.
  • a hydrogen filling station which has at least one device according to the invention.
  • the functioning of the device according to the invention for cooling a gas, preferably hydrogen, is based on the principle of so-called isentropic expansion, in which work is taken away from the gas in order to cool it down.
  • the device according to the invention for cooling a gas, in particular hydrogen as well as further advantageous embodiments of this device are described below.
  • the hydrogen preferably originating from a pressure storage tank of a hydrogen filling station (not shown in the figure), flows intermittently into the first end 9 of the piston chamber 2 via line 1, in which an inlet valve a is arranged.
  • a discharge line 10, having an outlet valve b, is also associated with this first end 9 of the piston chamber 2. Due to the pressure increase in the piston chamber 2, the hydrogen flowing in during an opening stroke of the inlet valve 1 displaces the liquid piston 3 located therein.
  • This piston is preferably formed by an ionic liquid and/or a liquid with a solubility for gaseous hydrogen of 0.0003 to 0.0005 g of hydrogen per g of liquid at a hydrogen partial pressure of 256 bar.
  • a piston 4 is arranged in the second and preferably opposite end of the piston chamber 2.
  • This piston is displaced by the liquid column 3.
  • the piston 4 performs mechanical work against a damper system.
  • This damping system is preferably designed as a spring-damper system, an electromechanical damping system, or a gas storage damping system.
  • the figure shows a spring-damper system consisting of a spring 5 and a hydraulic damper 6.
  • a control unit 8 is provided, which is operatively connected to the damping system and dynamically controls the pressure to be applied to the piston 4 by means of the damping system.
  • valve a When valve a is closed and valve b is opened simultaneously, piston 4 is moved downwards by the spring-damper system 5/6. This causes the liquid column 3 to push the gas volume 9 through the discharge line 10 into the vehicle tank (not shown in the figure). The gas transported in this way is thus The process is cooler than at the beginning.
  • the pressure ramp required to transfer the gas into the vehicle tank according to a common refueling standard, such as SAE J2601, is intermittently controlled by the dynamically changing counterforce applied to the piston 4 by the (spring) damper system.
  • This dynamic control is achieved via a control unit 8, preferably hydraulic, which dynamically adjusts or varies the pressure of the damper 6.
  • the heat generated during this damping process is dissipated from the piston chamber 2 and/or the damper system by suitable means. As shown in the figure, the heat can be released to the atmosphere, in particular via cooling fins 7.
  • the cooled gas flowing through the discharge line 10 can also be used to supply cooling to, in particular, a further cooling circuit not shown in the figure.
  • the pressure fluctuations occurring during the transfer of the gas or hydrogen into the vehicle tank due to the intermittent control can be buffered using conventional storage cylinders.
  • the gas drawn off through the discharge line 10 is mixed with at least one other gas stream to achieve the required or desired refueling conditions.
  • the liquid piston 3 is formed by an ionic liquid and/or a liquid with a solubility for gaseous hydrogen of 0.0003 to 0.0005 g of hydrogen per g of liquid at a hydrogen partial pressure of 256 bar.
  • means can be provided that generate a magnetic field in the region of the piston chamber 2. This allows the liquid piston 3, or the liquid used, to be stabilized so that little to no aerosols of this liquid enter the gas or gas mixture.
  • a separation device can be provided.
  • the device according to the invention for cooling a gas can be operated with any gases and gas mixtures.
  • the previously required pressure ramp regulator can be completely or at least partially replaced.
  • a chiller for cooling the hydrogen to be dispensed can be partially or completely dispensed with.
  • the invention enables a significant saving in cooling capacity in the range of 50 to 100%, depending on the refueling protocol, while simultaneously offering a cost-effective and wear-resistant design compared to other expansion machines.
  • the hydraulic control of the required gas-side pressure ramps can be achieved by sealing with an ionic liquid or a similar fluid, which improves the sealing performance, including in terms of long-term resistance. Furthermore, in a configuration with an electromechanical brake, electrical energy can be generated.
