Monica:

I am concerned that you don’t have experience in the fluid mechanics (& statics) involved in this application. You really should have a complete command of the hydraulics involved in “designing” a seal tank - particularly one for hydrogen service.

I’ve done a lot of these designs – especially on low pressure hydrogen generation and utilization pipe work or transport systems. The basic concept is very simple and involves only a basic knowledge of hydraulics – but that knowledge must be thorough. I will guide you through what I believe you should apply, but I will have to generate sketches or drawings to show you the basic principles of how such a “seal” tank is supposed to work.

I don’t understand what you mean by the terms “a small 6.5 ft safety tank” – I believe I can make an accurate guess at what you mean, but I need for you to confirm that. Refer to my follow-up post tomorrow that will have an attached Excel workbook for an explanation and feel free to make comments, ask questions, and voice any concerns. Do this with call-outs or text boxes – but make sure you question anything you don’t understand.

Right now I’m on my way out the door to a wine-tasting contest here in Madrid, Spain and I probably won’t get home until late. There is no rest for serious and dedicated wine tasters – especially in this country. I have spent the last year searching through Spain for the perfect wine bottle – and I haven’t found it yet, although I’ve come close to the goal. Like Don Quixote, my quest goes on and I won’t give up until I find the perfect bottle.

The seal pipe --inverse U--- must be minimum 11.0236 m above the level of water in the seal pot. This is calculated as the ht of water column corresponding to hydrogen pressure of 434 in water abs.

Monica:

Please read carefully the scope of work I assumed and which is on the workbook titled “Monica’s Seal Pot”. This explains a scope that I have to assume since you have not explained that nor given us details on what is your scope. A seal pot, by any other name, is still simply a relief device.

On the same post and directly below the workbook you downloaded is another workbook, albeit, compressed. That “zipped” file is “Art's Vessel Volumes Workbook”. Click on it and you will be able to download it.
