Abstract

Proses peleburan konsentrat tembaga menghasilkan gas buang yang mengandung sulfur dioksida (SO₂) dan partikulat halus yang berpotensi mencemari lingkungan. Untuk mengendalikan emisi tersebut, digunakan Wet Electrostatic Precipitator (WESP) sebagai teknologi pengendalian polusi udara dengan efisiensi tinggi. Penelitian ini bertujuan untuk menganalisis efisiensi aktual WESP pada tahap commissioning, membandingkannya dengan efisiensi desain, serta mengidentifikasi faktor-faktor yang memengaruhi perbedaan kinerja. Metode penelitian yang digunakan adalah deskriptif kuantitatif, dengan data operasional aktual periode Februari–April 2024. Parameter yang dianalisis meliputi tegangan, arus, kuat medan listrik, kecepatan migrasi partikel, resistivitas partikel, dan efisiensi penangkapan. Hasil penelitian menunjukkan bahwa tegangan aktual hanya mencapai 25–30 kV dari desain 80 kV, dengan arus 250–300 mA dari desain 800 mA. Efisiensi aktual WESP tercatat ±35%, jauh lebih rendah dibandingkan efisiensi desain sebesar 99,52%. Rendahnya efisiensi ini dipengaruhi oleh tegangan yang belum optimal, kondisi operasi yang belum stabil, serta faktor mekanis pada elektroda dan collecting plate. Kesimpulan dari penelitian ini adalah bahwa WESP memiliki potensi besar sebagai teknologi pengendalian emisi, namun optimasi parameter operasi sangat diperlukan agar efisiensi mendekati desain. Penelitian ini juga memberikan rekomendasi teknis untuk peningkatan kinerja WESP pada kondisi steady state.

===================================================================================

The copper concentrate smelting process generates exhaust gases containing sulfur dioxide (SO₂) and fine particulate matter that may contribute to environmental pollution. To control these emissions, a Wet Electrostatic Precipitator (WESP) is employed as a high-efficiency air pollution control technology. This study aims to analyze the actual efficiency of the WESP during the commissioning stage, compare it with the design efficiency, and identify the factors contributing to performance discrepancies. The research employed a quantitative descriptive method using actual operational data collected from February to April 2024. The analyzed parameters included voltage, current, electric field strength, particle migration velocity, particle resistivity, and collection efficiency. The results showed that the actual operating voltage reached only 25-30 kV compared to the design value of 80 kV, while the actual current ranged from 250-300 mA compared to the design value of 800 mA. The actual WESP efficiency was approximately 35%, which was significantly lower than the design efficiency of 99.52%. The reduced efficiency was influenced by suboptimal voltage levels, unstable operating conditions, and mechanical factors related to the discharge electrodes and collecting plates. It can be concluded that the WESP has substantial potential as an emission control technology; however, optimization of operating parameters is required to achieve performance closer to the design specifications. This study also provides technical recommendations for improving WESP performance under steady-state operating conditions.
