Abstract (en)
[origin: WO2018115661A1] The pressure regulation device (100) for a liquefied natural gas storage tank (200) comprises: - a pipe (105) for transferring boil-off gas of liquefied natural gas designed to be attached to an outlet (205) for boil-off gas from the tank, this transfer pipe being provided with a first discharging device (110) that is activated when the boil-off gas pressure in the tank is greater than a first predetermined threshold value, referred to as "P1," - a heat exchanger (115) for cooling and/or liquefying the boil-off gas discharged from the tank -between the transfer pipe (105) and the heat exchanger (115): -a temporary storage volume (125) of boil-off gas and -between the storage volume and the heat exchanger: -a second discharge device (130) designed to be activated when the boil-off gas pressure in the tank is greater than a second predetermined threshold value, greater than the first threshold value or - an expander (630) designed to be activated when the boil-off gas pressure at the exchanger and/or tank is less than a third predetermined threshold value, referred to as "P3," P3 being less than P1 and - a return pipe (120) for liquefied boil-off gas connected to the heat exchanger, the return pipe being designed to be attached to an inlet (210) for liquefied boil-off gas from the tank.
