There is a problem of pressure loss inside the tank truck
Thread Content
Our company transports its raw material products using tank trucks. By the time the loading is completed, there is usually still a pressure of 0.2 MPa remaining in the tanks, which often results in losses during weighing. Do you have any good methods for dealing with this issue or recovering the oil and gas from the tanks?
The pressure is indeed a bit high; a recovery system consisting of compression and condensation can be used, and there are examples of ammonia and propylene recovery. However, the compressor must be equipped with an inlet low-pressure interlock shutdown system

Are there any requirements for this compressor? For example, be careful with the model and type of pipeline – are there any requirements regarding power, etc.?
