The integral heat of solution in Equation 21, [DELTA][H.sub.s], can be determined by the following curve-fitted equations using the data given by Konnecke et al.
The partial molar enthalpies of water and TEG in Equation 21 can be evaluated by the integral heat of solution data in the water-TEG system through the use of the following set of equations:
[DELTA][H.sub.s] = integral heat of solution, kJ*[kmol.sup.-1]
