Standards for increasing temperature and pressure in chemical processing equipment
Thread Content
Are there specific standards for increasing the temperature and pressure of chemical processing equipment? For some equipment, the range is 15–25°C, while for others it’s specified to be below 50°C. In the case of hydrogenation processes, there are also pressure restrictions; for example, the pressure must not drop below 1/4 of the design pressure at temperatures up to 93 degrees. Where do these values come from?
Different heating methods result in different amounts of heat, which in turn leads to varying temperature increases. Different thermal conductive media and manufacturing materials are used, as well as different requirements for filling~~~~~~~~~~There is no fixed rule; for details, refer to the equipment’s design manual~~~~
For example, in the case of new processes involving 316L reactors (with linings), where the operating pressure is 13 MPa and the operating temperature is 310°C, how should this temperature rise be designed? As process developers, we need to provide such a curve

The pressure and temperature increases should be set based on the equipment’s stress curve as well as the stress curves of the relevant pipelines (there is a lower limit; values below this limit need not be considered~). If no such curves are available, stress analysis must be conducted~~~ Traditional calculation methods or finite element analysis can be used for this purpose. Please consult relevant materials on your own.
