If you would be interested in helping i came up with a Limited Oxygen Concentration Calculator for this isomerate material based on Estimated (Stoichiometric) Calculations, Experimental Calculations I was able to find, and calculations using LeChateleirs Mixing Rule being that the mixture is...

Im going to assume that the reason for the large safety factor would be because the level of variation in comparison with the hazard associated. Is there any background (book references etc...) providing supplemental information in using a 40% safety factor?

I read through the thread that you provided and got a little higher value based on the calculations i was referred to. I have found that toluene's experimental LEL is around 1.26 and you multiple that by the 9 decided from the stoicmetric conversion and you get around 11.4 compared to the 9.5...

Thank you this helped alot. Would you apply a safety factor (say like 25%) to the LOC calculations to ensure efficiency?

I found this example in some text C7H16 + 11 O2 = 7 CO2 + 8 H2O Air = 11/ 0.21 = 52.38 moles air /mole of C7H16 at stoichiometric conditions Could either of you explain the stoicometry used to develop the LEL from this equation. This will provide with a good example which I could use to...

This is a work related situation. We have a spherical tank that in the oncoming months will be filled with an Isomerate product and I was trying to assist someone in determining the proper amount of nitrogen to put on the vessel in order to eliminate the explosion hazard. This could be presented...

Oh ok can you assist me in determining LFL for chemicals........... As stated by 25362 LEL= (moles of O2/moles of fuel) so in terms of propane its LEL = (5 moles of O2/ ????) where do you determine the moles of fuel being that wouldnt it just be one mole of fule sorry my chemistry has left my...

Thanks guys...............Say your working with a UVCB compound thats compositions consists of multiple hydrocarbons. I played around with a couple simple equations to start with but when I used Latexmans theory it came out with a high percent of O2. Idk how applicable this is but just for...

Thank you for the information thus far but in research I have not been able to find out how they calculate the percentages based on the products (ex. propane, butane, etc...) such as that listed in the wikipedia page provided. I am more looking for how one would determine the percent nitrogen...

I am looking for a basis for LOC (same as Minimum Oxygen Concentration) when applying nitrogen purge to an Isomerate storage tank. Can anyone explain to me the tactics in developing this? I understand it is based on LEL and have seen variance based on pressure, altitude, etc.... Can someone help...
