Abstract:
A pressure vessel refuelling system enables fast fill refuelling of CNG fuel tanks by inducing a stratification of gas temperatures inside a tank during refuelling, then re-cycling a portion of the relatively warmer gas out of the tank during refuelling and back to a gas chiller. The system includes a pressure vessel having a lower end, a first gas port and a second gas port, wherein the second gas port is positioned above the lower end of the pressure vessel; and a cooling circuit connecting the first gas port with the second gas port; whereby gas flowing from an interior cavity of the pressure vessel through the second gas port is cooled in the cooling circuit before returning to the pressure vessel through the first gas port; and whereby a temperature of gas inside the pressure vessel varies from a first temperature at a level of the lower end of the pressure vessel to a second temperature, which is higher than the first temperature, at a level of the second gas port.
Abstract:
measurement device for monitoring the level of liquefied gas in a canister is described. The device comprises an array of at least three temperature sensors, configured to be mounted externally of the canister to extend from a first position on the canister to a second position on the canister. The device also comprises detection circuitry for detecting, when gas is released from the canister causing a temperature drop at the liquid-gas interface within the canister, a subset of the temperature sensors measuring a lower temperature than the remainder of the temperature sensors, and for identifying a current level of the liquefied gas in the canister based on the position within the array of the subset of the temperature sensors detected as measuring a lower temperature. This arrangement can be retrofitted to any canister, without the need to modify the canister or change the valve arrangement.
Abstract:
Bei einem Speicherbehälter von kryogenem Druckgas, insbesondere einem Kryodrucktank für ein Kraftfahrzeug, mit einem Speichervolumen zum Aufnehmen des gespeicherten Gases ist im Speichervolumen eine Mischeinrichtung zum Durchmischen des im Speichervolumen gespeicherten Gases vorgesehen.
Abstract:
Systems and methods for controlling the temperature and pressure of a cryogenic liquid methane storage unit are provided. The disclosed systems and methods generate methane gas from a reservoir of liquid methane stored within the methane storage unit, vent the methane gas through one or more outlet valves connected to the methane storage unit, and generate electric power using the vented methane gas. The generated electric power can then be used to initiating a cooling cycle, which reduces the temperature of said reservoir of liquid methane and reduces the pressure in said methane storage unit. Micro anaerobic digesters and methane storage units may be configured in a networked environment with a central controller that monitors remote units.
Abstract:
A low-temperature material transfer apparatus and a low-temperature liquefied gas supply system that uses the low-temperature material transfer apparatus characterized in that transfer means (2a, 2b) capable of output adjustment are installed in parallel, transfer means are operated at a low-output mode that is lower than the rated output so that the total output of transfer means 2a and 2b is controlled to be the desired quantity, and at the same time in the event one or both of the transfer means, or any of or two or more of the instrumentation devices related to the output of transfer means fall(s) into abnormal mode, the transfer means that fell into said abnormal mode is/are switched to shutdown mode, and the output of transfer means other than those that fell into said shutdown mode is/are switched to the rated mode so that the total output of the active transfer means is controlled to be the desired figure.
