Lower Flammability Limits and UFL and Solubility in Water 1

[osamahalihadi]

Hi,

Anyone have examples about how to calculate the Lower Flammability Limits and UFL for mixtures of compounds?
and Solubility in Water?

Kind regards

This subject is covered in Perry's Chemical Engineers' Handbook, 7th Edition pages 26-53 to 26-55.

Limits of Flammability of Gases and Vapors by Coward and Jones, Bureau of Mines Bulletin 503.

Flammabilty Characteristics of Combustible Gases and Vapors, by Zabetics, Bureau of Mines Bulletin 627.

Rules of Thumb for Chemical Engineers by Carl Branan, 2nd Edition, pages 276-278.

LeChatelier's Law is used for this and consists of:

Lm = 100/(x1/L1 + x2/L2 + xn/Ln) %(vol)

where:
Lm = upper/lower flammability limit of gas mixture
Li = upper/lower flammability limit of component i
xi = concentration of component i in gas mixture

Many Thanks.
