Initial temperature estimates may be provided to supplement temperatures determined by the Initial Estimate Generation Method. The entries are self explanatory, and correspond to the column condenser, top tray (tray two for columns with condensers; tray one for columns without condensers), bottom tray (tray above reboiler for columns with reboilers; highest numbered tray for columns without reboilers), and column reboiler.
Some of these estimated temperatures may be over-ridden by the estimate generator. For example, when the column condenser is bubble point liquid, the condenser temperature estimate is replaced by the bubble point of the estimated overhead product. For columns with conventional reboilers, the reboiler temperature estimate is replaced by the bubble point of the estimated bottoms product and so forth.
