Abstract

Proses pemurnian amonia memainkan peran penting dalam berbagai industri, seperti produksi pupuk, pendinginan, dan sintesis kimia. Laporan ini menyajikan analisis dan desain kolom absorpsi yang komprehensif untuk pemurnian amonia. Tujuan dari penelitian ini adalah untuk mengembangkan sistem yang efisien dan hemat biaya yang mencapai tingkat kemurnian amoniak yang tinggi melalui pemisahan pengotor. Untuk mencapai hal ini, dilakukan analisis persyaratan proses, termasuk komposisi umpan, kondisi operasi, dan spesifikasi produk yang diinginkan. Kolom yang dirancang akan menghasilkan konsentrasi akhir gas amoniak menjadi kurang dari 30 bagian per juta (ppm) dengan memanfaatkan air sebagai penyerap utama. Berbagai parameter desain kolom absorpsi, seperti pemilihan packing, dimensi kolom, dan material, dievaluasi dan dioptimalkan. Selanjutnya, simulasi model berbasis kesetimbangan dan laju serta pemodelan menggunakan persamaan termodinamika yang ketat dilakukan untuk menilai kinerja kolom absorpsi yang dirancang. Simulasi memungkinkan prediksi parameter operasional utama, seperti efisiensi pemulihan amonia, penurunan tekanan, dan konsumsi energi, membantu pemilihan alternatif desain yang optimal. Analisis sensitivitas dilakukan untuk mengevaluasi pengaruh variasi kondisi operasi dan komposisi umpan pada kinerja kolom. Hasil penelitian menunjukkan keberhasilan desain kolom absorpsi untuk pemurnian amonia, memenuhi output yang diinginkan di bawah 30 ppm amonia sambil meminimalkan biaya operasional. Desain optimal dapat menghasilkan 3,35 ppm gas keluar dan 34,9 °C dalam cairan keluar.

The ammonia purification process plays a crucial role in various industries, such as fertilizer production, refrigeration, and chemical synthesis. This report presents a comprehensive analysis and design of an absorption column for ammonia purification. The objective of this study was to develop an efficient and cost-effective system that achieves high purity levels of ammonia through the separation of impurities. To accomplish this, the analysis of the process requirements, including the feed composition, operating conditions, and desired product specifications, was conducted. The designed column will produce a final concentration of ammonia gas to be less than 30 parts per million (ppm) by utilizing water as the main absorber. Various absorption column design parameters, such as packing selection, column dimensions, and materials, were evaluated and optimized. Furthermore, equilibrium and rate-based model simulations and modeling using rigorous thermodynamic equations were performed to assess the performance of the designed absorption column. The simulations allowed for the prediction of key operational parameters, such as ammonia recovery efficiency, pressure drop, and energy consumption, aiding in the selection of optimal design alternatives. Sensitivity analysis was performed to evaluate the effects of variations in operating conditions and feed composition on the column's performance. The results of the study demonstrated the successful design of an absorption column for ammonia purification, meeting the desired output of below 30 ppm ammonia while minimizing operational costs. The optimal design could produce 3.35 ppm outlet gas out and 34.9 °C in liquid out.
