Agenda

●SimSci Reactor Model Updates

● SimSci FCC model for 2 Stage Regenerator

● SimSci Reformer Plant Step Change Test Validation

● SimSci Reactor Models in Pro/II

● Ammonia reactor models

●LP Update Tool


SimSci Reactor Models in Pro/II

●PRO/II Model

● All versions supporting the Excel Unit

operation

●Excel Interface

● Reactor configuration

● Component Lumping and Delumping

● Store results

●ROMeo

● Limited Model functionality

● Standardized Interface

● No user access required!


SimSci FCC 2 Stage Regeneration Enhancement

●Current SimSci FCC Model only has single stage regeneration

● Cannot handle RFCCs that has two stage regenerators

●Enhancement

● 2nd stage regenerator for coke and CO burn

● Rigorous Pressure balance model for 2nd stage regenerator

●Release

● ROMeo 6.2.1, end of September


SimSci FCC Model with 2 Stage Regeneration

●Support Two-Stage FCCs such as

● UOP RCC

● S/W RFCC

● KBR Modified Orthoflow F

●Single stage model remains the same

SimSci Reformer Plant Step Change Test Validation

●SimSci Reformer was configured and tuned to match customer plant

step test data

●SimSci Reformer model is in agreement with the trends of aromatics wrt

WAIT (weighted average inlet temperature)

●A simulator used by customer before shows different trends the

customer has believed for years

●SimSci Reformer tuning proven to be accurate and easy to implement
