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)

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.
