Abstract

PT Petro Jordan Abadi memproduksi asam sulfat menggunakan teknologi Double Contact Double Absorption (DCDA) di dalam reaktor converter berkatalis vanadium pentoksida (V₂O₅). Reaksi oksidasi SO₂ menjadi SO₃ ini bersifat eksotermis dan reversibel, sehingga sangat dipengaruhi oleh parameter suhu dan konsentrasi oksigen (O₂). Tugas khusus ini bertujuan menganalisis pengaruh penambahan gas O₂ terhadap tingkat konversi SO₂, profil suhu reaktor, dan produksi akhir H₂SO₄, serta menentukan kondisi operasi paling optimal. Penelitian dilakukan menggunakan perangkat lunak simulasi Aspen HYSYS dengan kondisi steady state dan pemodelan fluid package Peng-Robinson. Variasi penambahan konsentrasi gas O₂ yang diuji adalah 10,15%, 12,65%, dan 15,15%. Hasil simulasi menunjukkan bahwa penambahan O₂ sebesar 10,15% memberikan kinerja paling optimal. Pada kondisi tersebut, jumlah produksi H₂SO₄ mencapai nilai tertinggi sebesar 191,94 kg/h, dengan sisa emisi SO₂ paling rendah yakni 0,001139 kmol/h. Penambahan O₂ yang lebih tinggi (12,65% dan 15,15%) tidak memberikan peningkatan pembentukan SO₃ yang signifikan, melainkan justru berisiko menggeser kesetimbangan kembali ke arah reaktan akibat kenaikan suhu reaksi. Oleh karena itu, disarankan bagi perusahaan untuk menetapkan set point O₂ di angka ±10,15% pada Distributed Control System (DCS) guna menjaga efisiensi produksi yang tinggi, menstabilkan suhu alat, serta meminimalkan emisi gas buang.

PT Petro Jordan Abadi produces sulfuric acid using Double Contact Double Absorption (DCDA) technology in a converter reactor with a vanadium pentoxide (V₂O₅) catalyst. The oxidation reaction of SO₂ to SO₃ is exothermic and reversible, making it highly influenced by temperature parameters and oxygen (O₂) concentration. This study aims to analyze the effect of adding O₂ gas on the SO₂ conversion rate, reactor temperature profile, and final H₂SO₄ production, as well as to determine the optimal operating conditions. The research was conducted using Aspen HYSYS simulation software under steady-state conditions with the Peng-Robinson fluid package. The variations of O₂ gas concentration addition tested were 10.15%, 12.65%, and 15.15%. The simulation results show that the addition of 10.15% O₂ provides the most optimal performance. Under these conditions, the H₂SO₄ production reaches its highest value of 191.94 kg/h, with the lowest residual SO₂ emissions at 0.001139 kmol/h. Higher O₂ additions (12.65% and 15.15%) do not provide a significant increase in SO₃ formation; instead, they risk shifting the equilibrium back towards the reactants due to the rise in reaction temperature. Therefore, it is recommended for the company to set the O₂ set point at ±10.15% on the Distributed Control System (DCS) to maintain high production efficiency, stabilize equipment temperature, and minimize exhaust gas emissions.
