METHOD AND SYSTEM FOR PRESSURE MANAGEMENT WHILE EXTRACTING A LIQUID FROM A LIQUID STORAGE VESSEL

In a system (10) and a method for pressure management while extracting a liquid from a liquid storage vessel (11), a liquid (12) and its vapour (13) are provided in liquid storage vessel (11). The liquid (12) is extracted by a pump (17) from the storage vessel (11) and fed as a liquid flow (19) to a consumer unit (16). A defined partial flow (19a) is separated from the liquid flow (19) downstream of the pump (17). The pressure of the partial flow (19a) is reduced by a pressure regulation means (20) and the partial flow (19a) is evaporated by an evaporator (22). The evaporated partial flow (19a) is fed back into the storage vessel (11).
