Pressure design issues in the torch area
Thread Content
I have a question: Regarding the pressure at the boundary point where the refinery’s vent main leads to the flare unit, is the design pressure for this point provided by the refinery’s main design agency? Are it still the values provided by the torch manufacturer? My understanding is that it is the torch manufacturer who provides a minimum pressure value? Then does the main plant determine the diameter of the vent main and the pressure in the equipment boundary area based on this pressure along with the pressure drop in the piping network? So, is there a maximum pressure required for the boundary zone pressure of the torch device?
The maximum operating pressure, right? Considering the minimum backpressure, it’s possible that fluid won’t be able to enter the main pipe, as the pressure in the main pipe is high
My understanding is that the design pressure of the boundary zone should correspond to the pressure required during emergency pressure release

Based on the pressure drop of the flare tip provided by the flare manufacturer, calculations were carried out backward to determine the values for the flare main pipe, branch pipes, various vent pipes, and the outlet of the safety valve. :Lol, the general design institute is an organization responsible for overall coordination, and it is not necessarily the entity that designs utility systems as well as external pipeline networks.
An overall design institute is a facility that provides coordinated design as a whole, and it is not necessarily the entity responsible for designing utility systems and external piping networks.
Usually, the pressure is not this high, because cost considerations dictate that, while meeting the requirement for a minimum pressure drop, the pipe diameter is kept as small as possible. A bit more stress has no impact on emissions
The pressure at the flare boundary can be calculated based on the back pressure of the device’s vent safety valve.
Calculate the pressure at the boundary zone by turning around from the torch tip side.
