Simulation and Analysis of Renewable Biobutanol Production Using ABE Fermentation Technology in Aspen HYSYS
Project Description
Biobutanol production through Acetone–Butanol–Ethanol (ABE) fermentation is an important renewable energy technology that converts biomass into valuable fuels and industrial chemicals. In this project, a simplified process model is developed in Aspen HYSYS to simulate the production of biobutanol from corn-based biomass through fermentation and separation processes.
The process begins with the milling of corn kernels, where the raw material is prepared for further processing by reducing particle size. The starch present in corn is then converted into fermentable sugars through liquefaction and saccharification processes using simplified conversion reactors. These steps prepare glucose as the main substrate for microbial fermentation.
In the fermentation stage, glucose is converted into acetone, butanol, ethanol, carbon dioxide, and hydrogen using a yield shift reactor. The fermentation broth is then sent to separation units such as distillation and dehydration columns to obtain high-purity products. This simulation demonstrates how Aspen HYSYS can be used to analyze biofuel production systems and evaluate process performance.

Optimization Strategy
The modeling strategy involves representing each stage of the ABE fermentation process using Aspen HYSYS unit operations. The milling process is simulated using a user-defined model that represents simple physical conversion and energy requirements. Liquefaction and saccharification are represented using conversion reactors where starch is converted into glucose based on predefined reaction conversions.
The fermentation reactor is modeled using a yield shift reactor where product yields for acetone, butanol, ethanol, and other by-products are specified. After fermentation, downstreamseparation processes such as distillation and dehydration are used to purify the products. These operational strategies allow engineers to evaluate product yield, process efficiency, and system behavior under different operating conditions.
