I am determining the low and upper explosive limits for a gas mixture which comprises of the given compounds in the table below.
1) Methane 8.18% 2)_ Ethane 2.12% 3) Propane 1.47% 4) i-Butane 0.61% 5) n-Butane 1.22% 6) i-Pentane 0.32% 7) n-Pentane 0.42% 8) n-Hexane 0.4% 9) n-Heptane 0.2%
All the compositions are % by volume and all these gases are to be vented to a cold vent stack via a cold vent pit. I just need to know if there is a chance of some explosion by calculating the lower and upper limits as shown on the attached Excel sheets. Based on this attached calculation though, it does not seem likely that there will be chances of any explosion. However, I will appreciate if someone else can give a different opinion. The explosive limit for individual compound in the mixture is included on the attached Excel sheet.
