Abstract

Hidrogen merupakan salah satu gas yang memiliki banyak fungsi seperti agen sintesis senyawa organik , reaktan dalam proses hydrocracking, hidroalkilasi, dan hidrodesulfurisasi dalam industri petrochemical, reaktan proses hidrogenasi lemak dalam industri food and beverages, agen reduktor dalam industri material, produksi metanol, pembuatan silikon dan masih banyak lagi. Oleh karena itu proses pemurnian hidrogen sangat penting. Pressure Swing Adsorption (PSA) merupakan cara yang paling sering digunakan dalam memurnikan hidrogen. Hasil kemurnian hidrogen dalam PSA dipengaruhi oleh jumlah bed, jenis adsorben yang digunakan serta tekanan operasinya. Pemurnian hidrogen dengan unit PSA dapat dipermudah menggunakan software Aspen Adsorption. Dalam penelitian ini disimulasikan dengan 2 dan 4 bed dengan jenis adsorben silica gel, karbon aktif, dan zeolite serta tekanan operasi yang divariasikan antara 2 hingga 34 bar. Hasil simulasi menunjukkan bahwa sistem PSA dengan 2 bed untuk adsorben karbon aktif/ silica gel pada tekanan 7 bar diperoleh kemurnian hidrogen tertinggi sebesar 99,92% sedangkan kemurnian hidrogen sebesar 99,99% menggunakan adsorben karbon aktif pada 4 bed PSA dengan tekanan operasi 4 bar. Penelitian ini menggunakan data industri seperti PT Pertamina Cilacap untuk memurnikan hidrogen yang menghasilkan 87,92% pada tekanan 8 bar dengan adsorben molecular sieve pada 2 bed PSA =============================================================================================== Hydrogen has various functions in chemical industries, as an agent of organic compounds synthesis, a reactant in hydrocracking, hydroalkelation, and hydrodesulfurization process in petrochemical industry, a reactant in hydrogenated fat process, a reductant agent in material industry, methanol production, silicon manufacture, and many more. Therefore, hydrogen purification is very important process for the industry processes. Pressure Swing Adsorption (PSA) is commonly used hydrogen purification process. It is developed into the multi-bed process with combination of different adsorbent in every column at a step pressure equalization. Purification of hydrogen by PSA can be simulated using Aspen Adsorption software. This study simulated 2 and 4 beds PSA process with various type of adsorbent, those are silica gel, activated carbon, and zeolite with variation of pressure from 2 to 34 bar. Simulation results showed that 2 beds PSA using combination of activated carbon and silica gel at 7 bar gave the highest purity of 99.92% hydrogen, while 4 beds PSA using activated carbon as an adsorbent gave highest purity of 99.99% hydrogen at 4 bar. This study used industry data such as hydrogen purification process from PT Pertamina Cilacap and the result gave purity of 87.92% hydrogen at 8 bar using molecular sieve adsorbent in 2 beds PSA
