Abstract |
The article deals with the recent developments in the fuel industry, considering the permanent increasing requirements for fuel quality and environmental safety. The work aims to study
various technological modes at the rectification unit to produce fuel bioethanol from lignocellulosic
biomass. The main goals are to solve applied scientific problems of rational designing and technological optimization to obtain boundaries of energy consumption to ensure the quality of bioethanol
sufficient for a consumer. Recent approaches for numerical simulation of chemical technological
processes were applied to study the operating processes and optimize technological parameters. The
plant model was designed from various modules that allow us to simulate technological processes
efficiently and accurately for all the primary units of the rectification equipment. The methodology
based on the activity coefficient UNIFAC model of phase equilibrium was applied. As a result, a
mixture with 74% of bioethanol 9% of impurities was obtained in the brew column. In the epuration
column, a mixture of 46% bioethanol and 2.2% of impurities was obtained in bottoms. Finally, in the
alcohol column, the mass fraction of distillate of 96.9% and impurities of 2.7% were reached. The numerical simulation results can be applied in recent fuel technologies and designing the corresponding
biofuel plants. |
