Process Engineer, Air Products and Chemicals Inc. Professor of Chemical Engineering, University of California-Santa Barbara (Section Editor) Z. The dew point is estimated by iterative methods selecting K values at different assumed dew point (usually P or T are known) conditions, using y i/K i, the sum of which must equal 1 for the right (P,T) dew point selection.M. Sandler in Foundations of Computer Aided Design Vol2, p.83 (AIChE, 1981), may be used as practical and reasonable approximations.

However, in case of light hydrocarbons, the use of K i=y i/x i values taken from DePriester's graphs published by CEP Symposium Series No.7, vol.49, p.41, 1953, re-published in SI units in the CEP vol.74,(4), pp.85-86, April, 1978, or estimated by formulas as recommended by S.I. I must agree with him/her in that programs like the one he/she suggests are available, useful, and sometimes the only chance to reliably estimate VLE conditions for a mixture of chemicals.
To lad圜R, mirchee's approach using computer programs is known to me from another thread.
