#### Boil-Off Gas (Bog) Calculations For Cryogenic Liquefied Natural Gas Tanks

To add to this worthwhile contribution, I found this offering that outlines some potentially useful engineering criteria for some of the other contributions to BOG:

I can't vouch for the validity of some of the data but the principles appear sound to me at first glance.

#### Liquid Pipeline Surge

Hi Akur,

It's been decades that we've not communicated and hopefully you're still around in this time of Pandemic.

I'll appreciate if you could still send me "Pressure Drop Calculation Spreadsheet". I got lost of that copy a long time ago. I found it very simple & useful.

You can send it to my email at bert_abarilla@yahoo.com

Many thanks & wish you good health & your family.

#### Solid-Liquid Mixing In Agitated Vessels (Just Suspended Speed)

Hi ankur,

I have a question. I need to calculate the needed torque for the Impeller. Is it simply achieved by the T=r.V formulation? it means just multiply the speed of impeller to its radius?

regards

Hi Shakila21,

You can get the value of torque by multiplying the radius and force applied at a given RPM. But one needs to calculate Njs, P/V, Nre kind of parameters w.r.to lab scale to ensure the given RPM would be sufficient.

#### Solid-Liquid Mixing In Agitated Vessels (Just Suspended Speed)

Helpful calculations. But could you please explain how Njs depends on scale of manufacturing and liquid height inside the reactor?

According to the given formula, Njs would be same for a given impeller irrespective of batch size and % volume of reaction mass.

Dear Mr. Ankur,

How can we use/modify this spreadsheet for washing other gasses? For instance mixture of air and NOX and washable liquid would be water...
