Question regarding the unloading of liquid ammonia tank trucks
Thread Content
Question: When unloading ammonia from a liquid ammonia tank truck, high-pressure ammonia gas from the ammonia compressor is connected to the gas phase end of the tank truck, and unloading is carried out using pressure feeding. Does this manufacturing method violate relevant regulatory requirements, and is it in compliance with applicable laws and regulations?
Baidu: Selection of methods for unloading liquid ammonia tank trucks
The SOP for unloading operations should be established in accordance with the specifications
This unloading method is quite common; note that belt drives must not be used for ammonia compressors.
Thank you, I now understand clearly
There is no need for a liquid ammonia pump or an ammonia compressor; unloading solely by means of the pressure difference between the tank truck and the liquid ammonia tank works just fine. The gas outlet of the liquid ammonia tank is connected to the downstream equipment.
The compressor is unloaded: the intake port is connected to the gas phase of the liquid ammonia tank, while the exhaust port is connected to the gas phase of the tank truck; suction occurs on one side, resulting in pressure reduction, while compression takes place on the other side.

It should be that the liquid phase tank of the liquid ammonia tank truck is connected to the storage tank, the gas phase of the storage tank is connected to the compressor, and the outlet of the compressor is connected to the tank truck
