Simulation usingHYSYS or UniSimIt is a very serious error to show a pressure increase for a streamgoing through a heat exchanger Refrigeration and heating fluidsbuilt into HYSYS and UniSim For the initialLevel-1 simulation,use heaters and coolers. To find the heat

exchanger areas and utility requirements needed for economic analysis,use the following methods:

Heat exchanger sizing using HYSYS or UniSim

Reboiler and condenser sizing using HYSYS or UniSim

Heat exchanger design using UniSimIf UniSimsHeat Exchangers is also installed along with UniSimDesign, then heat exchanger details can be calculated rather thanestimated. The following methods are available: Shell and tube exchangers can be designed in UniSim Design as

follows. Open a heat exchanger and click on Design/Parameters/HeatExchanger Model and select UniSim STE Engine.

The following types of heat exchangers can be designed using the HeatExchanger engine:

CFE: CrossFlow Exchanger

FPH: Fired Process Heater

FWH: FeedWater Heat exchanger PFE: Plate-Fin Exchanger PHE: Plate Heat Exchanger STE: Shell & Tube Exchanger
