Abstract
Proses pervaporasi (PV) dalam rangka pemurnian etanol merupakan teknologi yang menjanjikan dan sedang berkembang pesat. Hal ini didukung dengan berbagai kelebihan yang dimiliki oleh pervaporasi yakni: tidak membutuhkan bahan kimia tambahan, proses lebih sederhana, serta tidak menimbulkan pencemaran lingkungan. Tujuan dari penelitiaan ini adalah untuk menentukan kondisi operasi optimal dalam proses pemurnian etanol menggunakan membran komposit poly-ether-sulfone dengan coating 3% alginat-3% kitosan. Penelitian ini menggunakan metode Rancangan Acak Kelompok (RAK) 2 faktorial 3 kali perulangan, faktor pertama variasi yaitu temperatur pre-heating bagian feed terdiri dari 63.64, 67.83, dan 72.01oC. Faktor kedua yaitu tekanan downstream yang terdiri dari 41.325, 46.325, 51.325 absolut kPa. Hasil konsentrasi pada feed dan fluks permeat akan dianalisa menggunakan ANOVA. Proses yang berjalan selama 40 menit dengan sistem batch dan konsentrasi umpan etanol sebesar 68.05%(w/t). Hasil percobaan menunjukkan konsentrasi etanol tertinggi didapatkan pada kondisi operasi pre heating feed 72.01oC dan tekanan downstream sebesar 51.325 Absolut kPa dengan konsentrasi etanol sebesar 82.84%(w/t). kondisi terbaik akan dikontrol menggunakan membran komposit non coating dan dihasilkan kenaikan konsentrasi etanol pada bagian permeat sebesar 76.34%(w/t). Namun performansi membran komposit poly ether sulfone dengan coating 3% alginate-3% kitosan ini belum mampu dalam memisahkan campuran azeotrop etanol-air.
English Abstract
Pervaporation (PV) is one of the ethanol purification technology, it was promising technology developing by the advantages: no need any chemical additive in the process, simple process, and did not caused environtmental damage. This research aimed to determine the optimal operating conditions in the process of purification ethanol using composite membrane poly ether sulfone modified by 3% alginate-3% chitosan solution coating. This experimental method used Randomized Block Design (RBD) with two factorials done by 3 times lopping. The first variation factor was pre-heating temperature which consist of 63.64, 67.83 and 72.01oC, the second factor was downstream pressure which consist of 41.325, 46.325 and 51.325 abs kPa. The result of feed concentration and permeate flux will be analized by using ANOVA. The operating process of this experimental was batch system during 40 min. Ethanol feed concentration which used was 68.05%(w/t), the experimental shows the highest ethanol concentration increased up to 82.84%(w/t) at the best operating condition of pre-heating temperatur at 72.01oC and downstream pressure at 51.325 absolute kPa. To knowing the effect of modification membrane by coating, ethanol purification done on the best operating condition and the same feed concentration using membrane composite non coating and the concentrastion increased up to 76.34% (w/t), but the performance of the composite membrane poly ether sulfone with coating 3% alginate-3% chitosan doesn’t capable in separating ethanol water mixture azeotrope.
