1. Crude Oil Refinery Heat Exchanger Network
Name: Trine Witzøe Supervisors: Johannes Jäschke & Sigurd Skogestad

2. Results so far

3. Jäschke Temperature
CaseI: Heat Exchanger E12 w/fouling resistance, CrudeSplit50/50
- Optimazation in Hysys gave
- Tfinal=75,55ºC & Thotfinal=55,46ºC
- Tjh1=-41,2ºC & Tjh2=-41,9ºC
- Using Adjust block on HotSplit with Tjhot equal gave
- Tfinal=75,56ºC & Thotfinal=55,46ºC

4. Planned work Optimize Heat Exchanger Network using Jäschke Temperature
Compare results and evaluate if there is cost savings in optimizing the split
Present results to Tüpras, Turkey
Look at some cases for Johannes Jäschke
