The selection of the constant-temperature dehydrogenation pressure in hydrogenation units
Thread Content
When the operating pressure of a hydrogenation unit is above 10 MPa, isothermal dehydrogenation is required during the pressure reduction process when shutting down the unit. Does anyone familiar with this process know what the specific constant pressure and temperature values are used during isothermal dehydrogenation? What are the criteria or calculation formulas for determining these values? Or is it just experience points? Thank you~ By the way, why is constant-temperature dehydrogenation required for pressures above 10 MPa? Is there any standard or design basis for this value?

It is determined based on the material properties of the equipment; we’re not very familiar with our own manufacturing processes
