Webreverse flow in TS when used with a new pipe module. To achieve desired rating accuracy, it is proposed that the flow rate sub-model in the underlying rating simulation be calibrated via nonintrusive flow data from an assembled system. Three innovative TS are being tested to validate the new modeling and the proposed test-and-rate method: two Weboverflows, and the flow to the reboiler is reduced until the friction losses drop to the available thermosyphon force. 8 - 6 PLANT DESIGN - Daniel R.
