PROCESS SIMULATION
Was familiarized with the use of Aspen HYSYS for steady
modelling, and carried out various simulations of;
• Condensate Separation Systems
• Dew point plant
• Refrigeration systems
• Hydrate inhibition models
Also attempted modelling of an Existing Production facility
(Erha FPSO)

Dew Point Plant with Refrigeration System
Analysis of Hydrate Inhibition Operating Cost
Cost of Hydrate Inhibitors
MeOH = $1.10/lb and 80% EG = $3.10/lb
For continuous operation for 5 years:
Methanol cost of 1431lb = $69 million
80% Ethyl Glycol cost of 4671lb = $634 million
Conclusion
Best choice is Methanol, because 80% EG is 9 times more
expensive.
