Thank you RVAmeche for your additional inputs.

Hi all, Just checked with some references for Swagelok PSV information and calculation and since it's a proportional relief device, can the rated flow the same as required flow (e.g. consider the scenario of Upstream Control Valve Failure)? Thank you

Thanks, I can check the design pressure of that. Dou you refer to Gas Lift Supply or N2 Gas Supply (referring to: "Well control panel gas inlet supply.")?

For that scenario, PSSV-124 upstream is installed to relieve any excess gas lift coming the well control panel. Both PSVs are set at the same set pressure of 1380 kPag.

1. This PSV is to protect the overpressure from Nitrogen Supply only. 2. The N2 is supplied from N2 cylinder (with max pressure of 21,000 kPag) with regulator BOC 8000 to regulate the outlet pressure of 1,000 kPag. Thanks for the inputs, I will double check also on the conversion factor for...

Thanks LittleInch and agree with you, it's should be in the range 250 psi. As per the vendor catalogue @ 21,000 kPag Inlet Pressure the flow stated as 1,086 L/min

Thank you Littleinch and geogeverghese fot your comment. I took the flow of 1,086 L/min as the required capacity of PSV 172 and I will check this flow against the installed PSV (Swagelok - D -Blue). With the below graph (estracted for swagelok R4 Serie) , I could estimate the capacity of PSV...

Hi All, I am trying to size a PSV (PSV172) for a Nitrogen Supply Line to Well Control Panel as per attached file. The PSV is installed on the N2 Supply Line with a set pressure of 1,380 kPag and Vent to Safe Location. I have some information of the Nitrogen Regulator (BOC Regulator 8000)...

Hi Everyone, I am looking for your advice with regard to the calculation I am currently doing to find the remaining life of dehydrator bed. Parameters: Inlet water concentration: 50 PPMV Target Outlet Water concentration: 0 PPMV Inlet Fluid Flow: 30 m3/h Operating Pressure of the vessel...

Dear Engineers I am looking for your advice with regard to the calculation I am currently doing to find the remaining life of dehydrator bed. For example: Inlet water concentration: 50 PPMV Outlet concentration: 0 PPMV Inlet Flow: 30 m3/h Operating Pressure: 16.7 barg Operating Temperature...

Hi All, Thanks for the response. Appreciate it. What I am doing at the moment is to determine what is the liquid volume left in the vessel if the level in the vessels reached LL and on this LL in millimeter (mm) what percentage of the level would be?

Hello Everyone, I am currently working a process to determine the liquid volume and level of level transmitter in a vessel. I am looking for some guidance and advice to perform liquid volume in a vessel and level transmitter calculation. I have two questions below: 1. How can I determine the...

Thanks Ehzin for you comments. What I meant with the trip is failure on the pump which leads to maximum discharge pressure of the pump flowing to the tank.

I have done the calculation for the vent as per API 2000. And the results show the existing vent with the size of 16" is adequate to handle the relief rate during relieving scenario. Just a follow up question regarding this discussion. I have scenario where the inlet fluid to the tank I coming...

Hello, I need help to checked the size of the vent, flow capacity and fluid properties at reliving conditions for Emergency Vent installed on Waste Water Tank. I am trying to use HYSYS simulation to do this, but it doesn't really work well with the below conditions. How is the best way to...

Hello, I am looking for some good reference to get better understanding in the use of Temperature Control Valve and Pressure Control Valve. I am not really sure how is the function of the TCV and PCV in controlling the flow through a pipe. I want to ask any help from you to give me some...

Thank you for the correction IRstuff. I meant "PYTHON"

Hello everyone, A good day to you all. I was thinking if i could be possibly get some guidance from this forum regarding Phyton Script. I hope some who is familiar with this program language can throw some knowledge in to this post. I am trying to build my script to generate a regression...

Thanks RVAmeche and Latexman for your comments on this post. I will take these information from you to do the investigation. I will come back with the response or questions to clarify with you,

Hi Engineers, I'm looking for some guidance to verify the required PSV shown in the datasheet is correctly stated. From PSV datsheet: Component = Nitrogen Vapour Required Capacity = 2,013kg/hr Normal Operating Pressure = 8.65barg Set pressure = 12.3barg Over-pressure = 10% Relief Temperature...
