Regarding liquid ammonia storage tanks and liquid ammonia spheres
Thread Content
Is it necessary to consider a filling factor when filling a liquid ammonia sphere tank with liquid ammonia? What about the liquid ammonia storage tank?
In AQ/T3017—2008 \"Guidelines for the Implementation of Safety Standardization in Ammonia Synthesis Enterprises\", 5.5.4.3, g) it is prohibited for the filling level of liquid ammonia storage tanks to exceed 85% of the tank’s capacity. In GB50160-2008 \"Code for Fire Protection Design of Petrochemical Enterprises\", 6.3.9 stipulates that the storage coefficient for tanks storing liquefied hydrocarbons, liquid ammonia, etc., should not be greater than 0.9. The amount of liquid ammonia to be filled is calculated as the volume of the tank truck in m3 × 0.80 (filling coefficient) × 0.61 (density) in T/m3; this amount must not exceed the maximum capacity limit specified for the tank truck, and overfilling is strictly prohibited. The maximum allowable filling volume of the storage tank shall be determined based on its actual volume and the liquid ammonia filling coefficient (0.52 t/m3). During filling, the fill volume must be strictly controlled and must not exceed the maximum allowable fill level of the storage tank.
