The document discusses using HTRI's heat exchanger simulation technology within the process simulator Petro-SIM. It describes how HTRI's rigorous heat exchanger models can be embedded within Petro-SIM using direct links, CAPE-OPEN, or the new XSimOp ShellTube model. The XSimOp model allows shell-and-tube heat exchangers to be simulated and rated directly within Petro-SIM in a robust yet fast manner, leveraging HTRI's research on heat exchanger performance prediction.

20. XSimOp ShellTube: Pros and Cons
• Advantages
– Designed for use within process simulators (robust and fast)
– Embedded as a native heat exchanger model (does not require separate
user interface)
– Licensed with Petro-SIM
• Differences
– Incrementation: 1D instead of 3D (Xist)
– Only inlet conditions are specified for both simulation and rating

21. XSimOp ShellTube: Pros and Cons
• Limitations compared to Xist
– Does not handle kettles and thermosiphons
– Limited tube types: plain and low-finned
– Limited tube internals: twisted tapes
– Limited baffle types: single segmental, double segmental, NTIW
– No design option
