Get this from a library. Computer-aided analysis of energy consumption in ethanol-water distillation operations. [X N Nguyen; E C Heyman; United States. Department of Energy,; Solar Energy Research Institute,] -- The energy consumption in a conventional ethanol distillation step can be reduced by adjusting the process parameters.

The most important process parameter. The item Computer-aided analysis of energy consumption in ethanol-water distillation operations, X.N. Nguyen, E.C. Heyman ; prepared for the U.S. Department of Energy represents a specific, individual, material embodiment of a distinct intellectual or artistic creation found in Brigham Young University.

Chi Tien, in Introduction to Adsorption, Adsorption Versus Distillation. Distillation, like adsorption and absorption, also belongs to the equilibration-diffusion category of separation processes, and is used for the separation of homogeneous liquid r, unlike adsorption or absorption, separation by distillation is effected by using energy instead of.

Computer-aided analysis of energy consumption in ethanol-water distillation operations. Technical Report Nguyen, X N; Heyman, E C. Existing computer programs have been used to evaluate the effects of various process parameters on the energy consumption of an ethanol distillation step.

A savings of kJ/mol ethanol produced is possible if the. Xinqiang You, Vincent Gerbaud, in Computer Aided Chemical Engineering, 1 Introduction. Extractive distillation is considered as an alternative distillation process to azeotropic distillation for the separation of azeotropic or close-boiling mixtures.

Hot topics of extractive distillation are focused on two main issues: entrainer selection and process optimisation. Literatures show that extractive distillation is more complex due to the design and process application and articles on energy consumption and cost.

Economic analysis shows that the energy consumption of the five-column scheme can be reduced by % compared to the four-column scheme. was used as a computer aided process engineering tool.

inhibition and distillation economics. Yeast is used for the conversion and the whole process can take up to 3 days. The result of fermentation is a mixture of ethanol, water and any solids that could not be converted to ethanol.

Continuous distillation is commonly used to separate the ethanol from the water. Purchase 26th European Symposium on Computer Aided Process Engineering, Volume 38 - 1st Edition.

Additionally, high purification costs occur due to an energy-intensive distillation step which is used, up to now, as purification technology for the recovery of n-butanol. Therefore, alternative separation processes are discussed in this study. Extraction and pervaporation are two unit operations with high potential to overcome this by:   COMPUTER AIDED CHEM.

(WHAT) • Molecule Draw/Model • Mixture/Solution Property Modeling • Assay Model • Model Unit Operations/Processes • Process Analysis • Operation Price/Costing Analysis • Energy Input/Output Analysis • Model of Automated Processes For a quick analysis of the possibilities and limitations of the distillation of the resulting ternary mixtures (original mixture + entrainer) we use the infinite reflux approach: Heavy zeotropic entrainer: The analysis illustrated in Figure shows that it is not possible to separate the original mixture into pure components 1 and 2 (both.

Additionally, azeotropic distillation may be used, adding a solvent such as decanol, which forms azeotropes with the contained components (with the exception of acetone) [34]. Kraemer et al. [4] have shown that >80% of the total energy demand of a distillation sequence is necessary for solvent separation from the aqueous stream.
