Systems and methods providing for the introduction of a dye, particularly a xanthene dye, and more particularly a rhodamine dye, to liquid anhydrous ammonia to discourage theft of the anhydrous ammonia and provide for leak detection in storage vessels. The dye will stain objects which come into contact with the liquid anhydrous ammonia allowing for the detection of such contact. Generally, the staining will be visible to the naked eye, but may also fluoresce when exposed to a particular light source such as ultra violet (UV) light.
La présente invention se rapporte à des systèmes et des procédés permettant l'introduction d'un colorant, notamment un colorant xanthène, et plus particulièrement un colorant rhodamine, dans de l'ammoniac anhydre liquide afin de dissuader du vol de cet ammoniac anhydre et permettant la détection de fuites dans des cuves de stockage. Ce colorant à pour but de tacher des objets qui entrent en contact avec l'ammoniac anhydre liquide, ce qui rend possible la détection de ce contact. Généralement, la coloration est visible à l'oeil nu, mais elle peut également émettre une fluorescence lorsqu'elle est exposée à une source lumineuse du type lumière à ultraviolets (UV).
