Along with that we are also planning to start a new series for interview questions. Hope you like it. Stay tuned with us. Thank you. Enjoy learning. All the best 👍

[@sagarsuroshe5030]

To deep & easily understood concepts. Sir can you make video for one example of PSV sizing and data sheet?

[@PayosAcademy]

Sure Sagar. We will surely cover this important topic in our upcoming videos. Stay tuned with us. Enjoy learning 👍

[@palleshivaprasad2554]

As you said, properties of fluid should be considered ay releiving conditions. But in practical, in H&MB we generally dont see operating parameter at relieving conditions (we can only see max temp,min temp, max pressure, min pressure) Where can we get parameters at relieving conditions?

[@PayosAcademy]

Absolutely correct Shivprasad. We will get properties at relieving condition from simulation softwares. Hope this will help you.

[@ABUBAKAR-ft8rv]

Great Job........really helpful. I have one silly question why do we need so many scenarios while designing a PSV? Why can't we only take set pressure as our design criterion along with buildup pressure and stuff?

[@SouvikRoy26]

bit off topic, I have experience of steam/condensate outlet to atmosphere, they are to be routed down to drain, otherwise it may lead to hot shower with condensate raining down

[@PayosAcademy]

Thank you for sharing your words Souvik. Its not off topic, you have triggered very important point which every chemical engineer should remember while considering vents and safety valves for steam lines. Thank you. we will be happy to hear more from you. Stay tuned with us. Thank you.

[@enjoywithme7880]

only relief rate need to calculate or wetted area need to consider, what input from process need to give to vendor? PSV sizing will be done by vendor.. Bahut confusion he plz explain on comment

[@PayosAcademy]

It depends on company. If they have good experience in designing PSV they provide directly orifice type and area also. But if they don't have confidence they share relief rate and scenario analysis with vendor he will size and provide the datasheets. Hope this will help you

How to find the beta value in thermal expansion scenario?

[@gauravpawar-r1n]

Waiting for a long for the new video. Can u pls take lecture on PSV sizing calculation using Excel sheet.😇

[@PayosAcademy]

Thank you Gaurav for your valuable suggestion. We will definitely work on it. Currently we are planning to upload a video on control valve sizing and start a new series for interview questions. But surely we will consider your suggestion for future. Thank you. Stay tuned with us. Enjoy learning 👍

[@lavkeshkushwaha8909]

Thank you so much Sir To make such a type of informative video. But Sir please make a vedio for doing calculation. And reduce Vedio uploading time because of after long time We forget prvs Vedio information.

[@WaleedDhokle]

Sir while sizing PSV we consider frictional losses less than 3%. But why don’t we consider static losses. If PSV is directly installed on the vessel than we can neglect it. But mostly PSV is installed on the Piping. So in this case, why don’t we consider static loss??

[@mahekverma5083]

You content is excellent, but excel calculation example for psv sizning would be really helpful.

[@PayosAcademy]

Thank you Mahek. We appreciate the feedback and will keep it in mind for future videos.

How to calculate latent heat of vaporization on Aspen.

[@PayosAcademy]

Good question Prathamesh. We will upload a separate video on this important topic. Stay tuned with us.

[@RavishankarPVarma]

I appreciate your efforts, sir! Can you explain how to evaluate Relieving temperature at Relieving pressure if relieving pressure is supercritical?

[@PayosAcademy]

Thank you Ravishankar. To know these values you must have ASPEN. There you can provide input for fluid and relieving pressure you will get all the properties of fluid at relieving pressure. Hope this will help you.

[@bukhari123456]

Plz make a video for PSV sizing using farmulas... Its important

[@Unknown_till_now]

Back pressure, suppose there are 4 PSV on a header for 4 different system are connected to the KOD, so the superimposed pressure will consider only due to KOD or we will consider all of the PSV open for back pressure calculation.

[@PayosAcademy]

It is not required to consider all PSV open scenario because this will only happen in case of fire, and also they should be available in same fire circle. Hence it is not necessary to consider all PSV open scenario. Hope this will help you. Enjoy learning, All the best.

[@Swp36]

Hi Sir, I really like your videos. Sir can you provide us some theory problem to solve on excel sheet for Pump, HE, PSV etc. whatever the topic you covered , at the end of video can you give us Theory problem.

[@deepakumar5438]

thank you for such informative content. please make part-04 of PSV sizing for calculation on excel as you uploaded for Line sizing calculation and Pump hydraulics calculation.

[@PayosAcademy]

Thank you for your valuable suggestion Deepa. We will surely work on it. Enjoy learning👍

[@mohitrana979]

Sir , if 5 kg/ cm2 pressure release through 1 inch vent then how many times required ( 5 kl vessel)

[@PayosAcademy]

You can calculate that based on velocity criteria and max flow possible through line size. We have covered one video for gravity flow with that reference you can calculate for your case. If you still have questions please feel free to get back to us. We will upload a seperate video on this important topic. Stay tuned with us.

[@sanjaypandey4908]

In case of wetted pool fire in eg of column if reboiler is isolated and if it falls in range of 7.5 m then it is also to be considered for PSV, like in our case there is thermosyphon reboiler there is no isolation valve so it's area along with column wetted area both to be consider or two different PSV one on column and one on reboiler to be consider pls justify.... Point no 2 for column there is a feed pump and if there is a fire then from discharge valve which is now isolated then the length to the column immediate flange, line hold up how it is to be consider for PSV design.

[@MuhammadFarrukhAskar]

Latent heat of vaporization kaise nikalte hai Aspen hysis mein plz help

[@PayosAcademy]

Very good question Pranali. In Aspen Hysis you will set of chemicals with different compositions just select your chemical and provide temperature and pressure. You will get latent heat of vaporization. Hope this will help you. Thank you 🙏

[@chaudharymuneer5830]

Sir I have one doubt My NPSH for vaccum distillation is coming negative as 0 absolute pressure in distillation and reflux sir please help is negative npsh ok for vaccum

[@PayosAcademy]

No muneer. Negative NPSH value will not be acceptable for pump operation. Not only positive you must maintain acceptable NPSHR for pump. For that you can either increase line size or increase the elevation of vessel. Hope this will help you.

[@chaudharymuneer5830]

To overcome the vaccum I will have to make elevation of atleast 10.2 m head? Sir can you make video on that and also video on control valve

[@rhashmi1]

[@random-bx8km]

Great work ! Hi @1:14:39 Inlet line size: its actually 3% of set pressure right? Also how to find the relief area after find the relief load is not discussed. Pls pin some ref in comment section.

[@PayosAcademy]

Yes correct. 3% of set pressure. We will upload a seperate video on relief area calculation. Thank you for your valuable suggestion.
