Why are there issues with pressure integrity, temperature, and pressure in hydrogenation reactors?
Thread Content
Why, when a hydrogenation reactor is sealed with high-pressure hydrogen, must the reactor inlet temperature reach a certain level once the pressure reaches a specific value? For example, the temperature must be raised to 100°C before the airtight pressure can reach 4.5 Mpa. Is this for the protection of the catalyst or for the protection of the reactor?
It is the temper embrittlement of austenitic stainless steel
Thank you for your reply. I have another question: does it matter to consider such issues when using steel like S32168? I majored in engineering, so I don’t know much about equipment and related materials. Please advise me

What was said on the 2nd floor is correct. This temperature is also related to technology; our requirement here is 93 degrees, although in the past it seemed to be 120 or even 150 degrees. I can’t remember.
The protection of the reactor is primarily aimed at addressing the temper brittleness of austenitic stainless steel; we keep the temperature below 135°C at pressures up to 4.0 MPa.
