Is the reboiler of a negative pressure tower considered a pressure vessel?
Yes, the reboiler of a negative pressure tower is considered a pressure vessel. A pressure vessel is a container that can withstand and transmit the forces of fluids such as liquids and gases under a certain pressure applied internally or externally. The reboiler of a vacuum tower is subjected to certain pressure under operating conditions, and therefore is classified as a pressure vessel. .
Check the actual pressure in the shell side; if it meets the requirements for pressure vessels, then it’s acceptable
This requires information such as your reboiler volume and pressure, and the determination is made based on the definition of pressure vessels
Vessels with a vacuum level below 0.02 MPa are not considered pressure vessels; they fall outside this category, are not subject to relevant regulations, and do not require inspection.
If the shell side is filled with steam, it is most likely a pressure vessel of the aforementioned type.
Let’s have such a question every day: Do the people driving on the roads have driver’s licenses? Since you asked, here’s the standard answer: those that meet the relevant criteria are considered pressure vessels.
Reboilers are generally heated by steam, and most of them are pressure vessels
