Determination of safety valve relief amount?
Thread Content
This post was last edited by tuotuo518 on 2010-1-8 13:23 I had the following problem when calculating the safety valve: The container contains gas (under operating conditions), but it is liquid under the discharge pressure (temperature or operating temperature), and it is a liquefied gas at this time. When I calculate the release volume, should I use the material flow rate entering the container or should I use the formula for the safe release volume of liquefied gas in the event of a fire? Question 2: For the gas in the container, when the outlet valve is closed, how to determine the gas temperature when the pressure in the container increases to the relief pressure? ?
Designers should be concerned about the questions that we, as users, just need to give answers to. Hehehehehehe! ! ! ;P
The first question of the original poster needs to be considered from two aspects. The overpressure protection of the safety valve under normal working conditions and under fire conditions must be met. According to our experience, generally the diameter of the safety valve that meets fire conditions is relatively large.
I am also struggling with this problem. It is about the selection and calculation of the safety valve of the TEG dehydration tower. Has the poster solved it? How to solve it? Thanks
