<p>A method of determining an average degree of saturation with ammonia (X) of a solid ammonia storage medium porous or not and capable of ad- or absorbing and desorbing ammonia reversibly in a storage container is described. A part of the volume (Vcon) of the container is occupied by gaseous ammonia of a pressure (p) and defines a free volume (Vfree). Ammonia flows out of the container with a flow (f). n pairs ((f i , p i ), (F i p i )) of flows (f i ), or accumulated flows (F i ), and pressures (p i ) are sampled at a sequence of points of time (t i ), i= 1....n and n = 2; an estimate volume value (V fit ) on the basis of the sampled pairs ((f i , p i ), (F i , p i )) is determined; and the degree of saturation with ammonia (X) is determined by applying a predetermined correlation (Rel) between a plurality of estimate volume values (V fit ) and a plurality of values of the average degree of saturation with ammonia (X) to the determined estimate volume value (V fit ).</p> |
