Abstract
A method and system for determining a momentary boil-off rate for a storage tank for a natural gas in liquid phase and gas phase. A mass flow from the gas phase of the natural gas at an discharge pipeline of the storage tank and a mass flow into the liquid phase of the natural gas at an loading/discharge pipeline of the storage tank is determined. A volume, a temperature and a pressure of the gas phase of the natural gas is measured. A dynamical model is applied to the determined values to determine the momentary boil-off rate.
