Aspen Hysys Simulation Question 1
The purpose of this analysis is to design and optimize the
flash separation system of simple process flow sheets of
hydrocarbon process. This process also explains energy
requirement of separation systems. We have a feed stream
containing 15% ethane, 20% propane, 60% i-butane and
5% n-butane at 50°F and atmospheric pressure, and a
flow rate of 100 lbmole/hr. This stream is to be
compressed to 50 psia, and then cooled to 32°F. The
resulting vapor and liquid are to be separated as the two
product streams in flash separator. Answer the following
questions.
1). Clearly draw the process flowsheet for above process?
(1 Mark)
2). Draw the neat simulation flow sheet manually (Similar
to ASPEN HYSYS) and specify the units and streams
involved? (1 Mark)
3). Write the difference between the process flowsheet
and simulation flowsheet with help of 1) and 2). (0.5
Marks)
