Question

Review the COX chart with its many lines (different species each). Collapse to one line by posing a "theory of corresponding states model". (e.g pose Tr and Pr as variables). Plot the result. Consider the ammonia reaction at 1000F and 2200 psia pressure. The Kf = 0.76times10-4 Find the reaction conversion, s, incorporating the fugacity coefficients (K phi ). Compare the conversion, e, by neglecting K phi) (i.e K phi =1). Figure 6.1-4 Cox chart vapor pressure plots. (From A. S. Foust el al., Principles of Unit Operations, Wiley, New York, 1960, p. 550.) appendix Generalized Fugacity Coefficients of Pure Gases and Liquids (Zc = 0.27) Third Edition, by 0. A. Hougen. K. M Watson and R.A permission of John Willey and Sons. Inc.)

Explanation / Answer

2) Reaction conversion (epsilon) = (Temp. * pressure)/Kf = 1000*2200/(0.76*10-4)

= 2.9*1010
