I i Three-phase SeDarator For the three-phase separator overheads, the effect of the correlation option is given in Table 3. There is some improvement using the petroleum-liquids option set. Use of the coal-liquids option set results in an overall error for total mass flow of overhead of 1.862, and the petroleum-liquids option set results in an error of 0.73%. TABU 3.

There is improvement using the petroleum-liquids option set. Use of the coal-liquids option set results in an overall error for total mass flow of over- head of 16.42, and the petroleum-liquids option set results in an error of only 1.37%. TABLE 4.

Total mass flow of overhead and 219
ottoms is less sensitive to the number of theoretical stages than are the individual distillate fraction flows. The effect Of the correlation option set (coal-liquids vs. petroleum-liquids) on the vacuum fractionator simulation perfor- mance was determined. Since simulated distillate flows were in considerable dis- agreement with experimental values for the reported operating pressure of 0.94 psia, additional simulation runs were made to observe the effect of assumed column pressures. For the petroleum-liquids option set, a value of 4.5 psia gave the best match of calculated total overhead and bottom flows to experimental flows. Correspondingly, a value of 6.0 psia was found for the coal-liquids option set. Given that the reported column pressure, 0.94 psia, is closer to 4.5 psia than to 6.0 psia, this result gives ail indirect indication that the petroleum-based option set better describes the experimental system. The actual operating pressure for the vacuum fractionator was known to increase above 0.94 psia during the experi- mental run, but no information is available as to the extent of increase. The results for the flows of the distillate fractions are presented in Tables 5-7. Table 5 represents results for vacuum bottoms flows, and Table 6, for vacuum over- head flows (calculated vacuum overhead flows also include values for debutanizer bottoms flows in order to agree with experimental measurements). Table 7 gives a comparison of the pressure and correlation option set in terms of an overall per- centage error for both bottoms and overhead at the operating pressure of 0.94 psia. Use of the petroleum-liquids option set gives better agreement, although the percentage of error relative to experimental error is still considerable. TABLE 5.

(<strong>co</strong>al-liquids vs. petroleum-liquids) on the vacuum fraction<strong>at</strong>or simul<strong>at</strong>ion perfor-<br />
mance was determined. Since simul<strong>at</strong>ed distill<strong>at</strong>e flows were in <strong>co</strong>nsiderable dis-<br />
agreement with experimental values for the reported oper<strong>at</strong>ing pressure <strong>of</strong> 0.94<br />

Correspondingly, a value <strong>of</strong> 6.0 psia was found for the <strong>co</strong>al-liquids option set.<br />

Table 5 represents results for vacuum bottoms flows, and Table 6, for vacuum over-<br />
