I’m seeking help from experts – is there any information regarding the process of filling hydrogen gas and liquefying oxygen?
Thread Content
I’m seeking help from experts – I need a process flow diagram, even a simplified one, regarding the filling of hydrogen into torpedo vehicles, as well as the vaporization processes of liquid oxygen and liquid nitrogen.
Is there demand for this process nowadays? !
This will have difficulty passing fire safety inspections
I don’t understand what your purpose is. If a torpedo vehicle is filled with hydrogen, then if you have the necessary qualifications, it won’t be a problem. Gasification is quite simple: for low pressure, it can be carried out directly in a heat exchanger based on the pressure in the storage tank (or Dewar flask). If high pressure is required, a piston pump can be used to increase the pressure for gasification.
The key issue is that there is huge pressure regarding fire safety and environmental protection at the moment, making things difficult to handle
Since I’m not familiar with it either, I’m not sure if there’s any demand. Thank you
I want to learn about this filling process, to find out what needs to be paid attention to and what components need to be added. Does liquid oxygen/liquid nitrogen vaporization take place by going directly from the liquid oxygen/liquid nitrogen storage tanks to the vaporizer? If high pressure is required later, does liquid oxygen/liquid nitrogen need to be pressurized by a plunger pump and then vaporized in a vaporizer?
Yes, it’s not easy; it’s very difficult
The basic process is as follows: cryogenic liquids such as liquid oxygen, liquid nitrogen, etc. — cryogenic liquid pump — high-pressure air bath vaporizer — main filling valve — divided into three branches, with a pressure gauge on one of the branches； Relief valve along the way ； A bus runs along the way to fill the gas cylinders. This is the basic process; if one wants to work in this position, it is necessary to undergo training and obtain a certification designated by the local **work safety authorities. The skills required for this position need to be demonstrated through hands-on practice on site. When handling gas cylinders, experienced workers can operate two cylinders at a time.
