1 .3 .3 Computation of Bubble Point Temperature

Problem statement
Compute the bubble point temperature at 18 bar of the following hydrocarbon mixture
(see Table 1.1) using the RK-Soave property method.
TABLE 1.1

Component Mole fraction
Ci 0 .05
c2 0 .1
C3 0 .15
i-C 0 .1
i
n-C 0 . 2
i
i-C5 0 .25
n-C 5 0 . 15

Assume the mixture inlet temperature of 250C, pressure of 5 bar and flow rate of
120 kmol/hr.
