This report presents the results of component balances for the internal streams on Process Development Unit P-99 for nine SRC-II runs (Runs P99-63 through P99-71). These results provide reliable rates and compositions for all the streams in the high pressure separation and fractionation sections. The development of improved sampling techniques and computational procedures to handle deficiencies and inconsistencies in the data were responsible for producing these consistent material balances. The effect of temperature on the fraction of the separator feed that ended up in the gas phase was studied during these runs. Increasing the temperature increased the amount of material in the gas phase. The hot separator temperature was limited to 780 to 800/sup 0/F due to the potential for coke formation. A temperature of 600/sup 0/F was necessary for the first intermediate separator to prevent salt deposits from plugging the transfer lines. Recycle water composition was affected by the amount of fresh water injected between the separators. Rates and compositions of the flash gases from pressure letdown of the high pressure separator oil streams and components heavier than n-pentane in the debutanizer off-gas determined for Run P99-84 were incorporated into the data from Runs P99-63 to P99-71 to substitute for missng data and improve the material balances.
