Process Simulation And Research Of Separation Technique Of Active Amyl Alcohol And Isoamyl Alcohol

Separation of active amyl alcohol (2-methyl-1-butanol) and isoamyl alcohol (3-methyl-1-butanol) from fusel oil can not only change waste into valuables, but have important economic, social and technology innovative benefits. Separation technique of active amyl alcohol and isoamyl alcohol was done a further study in this paper, and got a better result. The optimum operating conditions of the batch distillation (BD) and batch extractive distillation (BED) for separating active amyl alcohol from isoamyl alcohol were found by applying CC-BATCH by using UNIFAC group contribution method and Wilson equation, a BD model of the chemical engineering simulative system named ChemCAD5.2. Optimum operating parameter was got by simulating and calculating process of BD using yield or gain as a criterion. The process was done with amyl alcohol in which the concentration of active amyl alcohol was from 0.6 to 0.9(mass ratio). The results indicated that the simulation was consistent with the experiment and the maximum yield deviation is about 7.3%. In this paper, a simulation and optimization was done to separating active amyl alcohol from isoamyl alcohol. It is calculating faster, consuming time less, error little, and can save a large number of manpower and resources. It would be greatly beneficial to industrialized production or process development. In addition, a preliminary simulation and optimization to the process of BED for separating active amyl alcohol and isoamyl alcohol have been done. Compared the results of BED's simulation with BD's, theory stages number N and reflux ratio R both decrease .The yield of 2-methyl-1-butanol increased from 0 to 44.3%.
