MARRIAGA, NILSON. PERFORMANCE INDICATORS OF BIOETHANOL DISTILLATION. Dyna rev.fac.nac.minas [online]. 2009, vol.76, n.159, pp.85-92. ISSN 0012-7353.

The increasement of biofuels demand accelerates the construction of new production plants and technological improvements in the process so the development of versatile tools for evaluating alternatives becomes an undeniable challenge. It was established through heuristic rules, thermodynamic analysis and simulation computer the energy consumption and performance indicators that govern, from fermented mash (ethanol 8.5 % v/v), the distillation of various capacities for bioethanol production: 20, 60, 100 and 150 KLD (kiloliters / day) through Aspen Plus^TM simulator. It was found that the distillation demand nearly 30% of heat that would be obtained by burning alcohol fuel produced thus it is necessary the use of raw materials that generate enough biomass to produce the steam required. In addition, correlations were found to allow for easy diameters of distillation columns in terms of production capacity.

Palabras clave : ethanol distillation; distillation column; exergetic analysis; biofuels.
