Abstract:
In this work, the process of ethane recovery plant was simulated for the purpose of Front End Engineering
Design. The main objective is to carry out a series of simulation using Aspen HYSYS to compare recovery of
ethane from Joule Thomson (JT) Valve, Turbo-Expander and Twister Technology. Twister technology offers
high efficiency, more ethane recovery and lower temperature than JT valve and turbo-expander process. It lies
somewhere between isenthalpic and isentropic process due to its mechanical configuration. Three processes
were compared in terms of recovery of ethane. To conduct the simulations, a real gas plant composition and
design data were utilized to perform the study for comparison among chosen technologies which are available
for ethane recovery. The same parameters were used for the comparisons. Effect of operating conditions
including pressure, temperature, and flow rate as well as carbon dioxide on the recovery of ethane was
examined.
