Question about the pressure reduction valve for hydrogen cylinder sets?
Thread Content
Currently, the company uses hydrogen cylinder sets for its hydrogenation reactions; the reaction pressure is 5–6 kilograms, while the pressure in the hydrogen cylinder sets is around 150 kilograms. The existing design makes use of pressure regulators on the hydrogen cylinders. Are there any pressure regulators available for hydrogen pipelines that can reduce the pressure from 150 kilograms to around 10 kilograms? (I have used some valves, but when the hydrogen flow rate is too high, the pressure gauge basically stops working.)
Pressure regulators do not have such a wide range of pressure adjustment; it is recommended to use a three-stage pressure regulator. With the first stage, reduce the pressure from 150 to around 100, then from 100 to around 30-40, and further from 30-40 to 10. This approach will result in more stable pressure levels.
Hydrogen pressure regulators come in different flow rates; the commonly used ones have a flow rate of around 15 M3 per hour, though there are also regulators that can achieve flow rates of over 50 M3 per hour.
