LEL of Ethylene Oxide in CO2 2

[Jkaen]

Hi Guys,

I have read this thread

http://www.eng-tips.com/viewthread.cfm?qid=33615

And while it helps in general terms with diluted hydrocarbons I am struggling to apply it to Ethylene Oxide (LEL 3%, UEL 100%)

It is my thinking from a pure common sense viewpoint that as EO produces its own oxygen (hence the 100% UEL) that the fact it is in CO2 rather than air will have little effect on the LEL, can anybody confirm or refute this please?

I do not agree that they are necessarily the same. I think the LEL is a function of many factors such as flame speed, relative size of molecules etc..

especially the triangular diagram in Fig. 2.3 "Flammable region of EO/CO₂/Air mixtures.

Perfect 25362, that was just what I was after and somehow failed to find with 2 hours of googling, thank you very much.
