Questions about vent pipelines
Thread Content
Someone proposed that the vent line should be connected directly to the vent flare! And there must be no throttling and pressure-reduction facilities! ”Is this setting reasonable? Thank you!
In that case, isn’t it an excessive investment to simply vent hundreds of kilograms of pressure? !
Reply 1# lflsedin: The vent pipeline is usually quite thick, and this actually helps to reduce pressure as well.
The diameter of vent pipes is generally large and the pressure is very low, so they can likely be sent directly to the flare for combustion. If a pressure-reducing device is added, it may hinder venting, going against the original design intent.
“The vent pipeline should be connected directly to the vent flare! And there must be no throttling and pressure-reduction facilities! ” This is the correct way to handle it. Because, generally, a safety valve itself has the function of reducing pressure. In other words, once the safety valve opens, fluid is discharged directly into the main pipeline; the addition of throttling devices can easily create resistance, leading to vibrations that have a significant impact on the safety of the pipelines, and this force is difficult to calculate.
It’s unreasonable; the vent main pipes are large in diameter. When discharging from medium- and high-pressure systems, this results in overly thick walls for the discharge pipelines, leading to high costs
Is the venting regulated through a control valve, and is there any issue with using the control valve to reduce pressure? !
