• Solid Handling Capabilities - Specific unit operations, such as Vibrating Screen, Baghouse Filter, Centrifuge, Conveyor, crusher and Rotary Breaker, become availabile in R370.  Other unit operations such as pump and pipe are enhanced to deal with slurry systems.
• UniSim Design in the UniSim Operations Suite - UniSim Design is the primary simulator technology used in the UniSim Operations Suite. R360 includes a number of models ported from the Shadow Plant simulator, including a Tube Bundle model and a Hydrotreater model. Additional models continue to be ported over as needed.  R370 incorporates the UOP CCR dynamic model for OTS applications.
• Support for Aspen HYSYS Simulation Cases - UniSim Design R370 supports the reading of any simulation case saved by Aspen HYSYS 2006 or earlier. It also supports writing out a UniSim Design simulation case in HYSYS 2006 format so simulation cases may be shared between UniSim Design and HYSYS in both directions.

UniSim Heat Exchangers
