Removing oil contaminants from filtered ammonia

This problem also troubles us; fellow sailors who have good solutions could please offer some guidance.
Solved through investment................, centrifugal compression requires no oil..............The product ammonia is oil-free.
If centrifugation is not used, does the current situation prove that it can be solved? Does anyone have any good suggestions?
An oil filter can be added. This problem generally only occurs with reciprocating pumps in small devices. Centrifugal pumps do not have this problem.
What type of oil filter should be added, and what is its internal structure?
In the urea ammonia advanced stage, there is an ammonia filter; there’s a pipe at the top that is used for draining oil
Isn’t the pipe at the top used for exhaust? How can oil be drained? Besides, the buffer tank isn’t full either, right? How do I drain the oil?
You’re not familiar with the internal structure of the device; it appears to be at the top from the outside, but in reality it’s located at the bottom of the built-in filter basket. Oil is heavier than ammonia, understand?
