METHOD OF CALCULATING THE STATIC PRESSURE WHEN TRANSFERRING A GAS BETWEEN A PRESSURE OR LOW PRESSURE SOURCE AND AT LEAST ONE RESERVOIR

摘要

This method of calculating the static pressure during the transfer of a gas between a source of pressure (17) or depression and at least one reservoir (8 to 10, R), the transfer can be carried out in both directions, comprises at least the following steps: - a) take into account the unit volume of the tank (s) (8 to 10, R), - b) know the physical characteristics of the gas transferred, - c) determine the pressure losses in pipes connecting the tank (s) (8 to 10, R) to the pressure source (17) or vacuum, - d) defining a target static pressure to be reached in the tank (s) (8) to 10, R), - e) measuring a total dynamic pressure between the source of pressure (17) or depression and the reservoir (s) (8 to 10, R) during the transfer of the gas, - f) calculate , taking into account the values obtained in steps a) to e), a static pressure of the gas present in the reservoir (s) (8 to 10, R), - g) stop the tra Gas supply when the calculated static pressure corresponds to the set static pressure of the tank (s) (8 to 10, R), - (h) perform a check of the calculated static pressure of the tank (s) (s) ( 8 to 10, R), after balancing the pressures between the reservoir (s) (8 to 10, R) and the pressure source (17) or depression,
