Regarding the distance between liquid ammonia storage tanks and their loading/unloading nozzles
Thread Content
Regarding the distance between liquid ammonia storage tanks and their loading/unloading nozzles: 1. According to petrochemical regulations, there are no specifications regarding the distance between loading/unloading nozzles and liquid ammonia storage tanks; what is specified is the distance between the vehicle-based loading/unloading stations and the storage tanks. Referring to an above-ground loading/nozzle as a loading station is a bit exaggerated. · 2. In accordance with building codes, the distance between storage tanks and their loading/unloading nozzles is specified, but this applies only to dome tanks and floating roof tanks; liquid ammonia is generally stored in horizontal tanks, so these regulations do not apply in that case. So what exactly is the spacing? Please don’t say that things have to be done strictly – that’s nonsense; who doesn’t know that? I just want to know if there are really any loopholes in this.
When using a liquid ammonia pump for filling, the distance between the liquid ammonia loading/unloading crane and the filling pump should not be less than 8 meters； On the liquid ammonia loading and unloading pipelines located more than 10 m away from the loading/unloading crane positions, in addition to emergency shut-off valves that facilitate operation, remote shut-off devices should also be installed ； The distance between the loading and unloading cranes for liquid ammonia vehicles should not be less than 4 m.
The loading and unloading hose on the ground is the loading and unloading platform
