Abstract
High purity of Bioethanol is required in biofuel mixing with gasoline (EXX). In bioethanol production line, the azeotropic property of ethanol-water becomes the barrier for purification process. This study examined two bioethanol separation processes by support of simulation tools, Superpro Designer 9.0 software. Ethanol purity and a low costeconomical process were the major considerations. Purification method of vapor permeation membrane technology was compared with distillation-adsorption method. Data from previous lab experiments and some literatures were used. The results showed that distillation-adsorption method is more economical compared to vapor permeation technology. Payback period of the simulation is 3.9 years and 4.3 years to distillation adsorption and vapor permeation respectively with each IRR value is 20.23% and 17.89%. Initial investment value of vapor permeation is 9.6% higher than distillation method. Significant difference observed in operating costs, since more units involved in vapor permeation require more labors to operate.
Bahasa Abstract
Simulasi Pemurnian Dengan Permeasi Uap Dan Distilasi-Adsorpsi Pada Pabrik Bioetanol. Bioetanol dengan kemurnian tinggi diperlukan dalam pencampuran biofuel dengan bensin (EXX). Pada proses produksi bioetanol, sifat azeotropik etanol-air menjadi penghalang untuk proses pemurnian. Penelitian ini mengkaji dua proses pemisahan bioetanol dengan bantuan piranti simulasi, Superpro Designer 9.0. Kemurnian etanol dan biaya proses ekonomis rendah menjadi variabel utama. Tulisan ini membandingkan metode pemurnian teknologi membran permeasi uap dengan metode distilasi-adsorpsi. Data yang digunakan untuk simulasi berasal dari percobaan laboratorium sebelumnya dan studi pustaka. Hasil penelitian menunjukkan bahwa metode distilasi-adsorpsi lebih ekonomis dibandingkan dengan teknologi permeasi uap. Payback Period dari simulasi ini adalah 3,9 tahun dan 4,3 tahun untuk distilasi adsorpsi dan permeasi uap, secara berurutan. Nilai masing-masing IRR adalah 20,23% dan 17,89%. Nilai investasi awal permeasi uap lebih tinggi dibandingkan dengan metode distilasi yaitu 9,6%. Perbedaan signifikan diamati dalam biaya operasi, karena lebih banyak unit yang terlibat dalam permeasi uap memerlukan lebih banyak tenaga kerja untuk beroperasi.
