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.

Sandler in Foundations of Computer Aided Design Vol2, p.83 (AIChE, 1981), may be used as practical and reasonable approximations. egingroup idkfa Ok an example,we have mole fractions and temperature, and we want dew pressure, so we take two arbitrary pressures and calculate summation of y/k, which yz because we are in dew point,and k earned by DePriester,so if we try this summation in 100psi we get 0.828 and if we try it in 150psi we get 1.174, and finally if we try 126psi we get 1 and thats the dew pressure,i. a green line connects these two points The green circle indicates.

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.
