Ethanol Process HYSYS Simulation and Optimization: A Case Study of Kenana Ethanol Plant

الملخص

In this paper Kenana ethanol plant has been simulated by the
simulator tool of Hysys. The thermodynamic properties are calculated with
NTR property package models, which are available in HYSYS simulator
program. Ethanol is a renewable resource of energy and is potentially cleaner
alternative to fossil fuels. Also it is a very important basic chemical, widely
used in different industrial sector and It is the most important and popular
fuel in the current era and future as well. In new processes development, the
analysis of an industrial plant through simulation may frequently indicate,
beforehand, whether it is technically and economically feasible. In the case of
existing plant (Kenana Ethanol), already in operation, the process simulation
can help optimizing their operational conditions, obtaining products of better
quality as well as reductions in energy consumption and other process losses.
The main purpose of the study is to simulate and optimize the annual profit
96% ethanol plant by Aspen HYSYS 3.2. In order to simulate this process
some process operational data of the ethanol plant of Kenana ethanol are
used. The optimization criterion of the process is to maximize the annual
profit. This study will be very helpful for the plant operators to run the
factory efficiently by minimizing the process system requirement. The results
show that the ethanol recovery in mass fraction was 96.35 by using HYSYS
program while 92% mass fraction plant. In the stillage the ethanol was found
3.75% in case plant while 0.06% mass faction in case of HYSYS this
differences attributed to un-optimized condition in plant.
