Coal Power Plant (PLTU)
Industrial mineral solutions — PT Wira Energi Utama, North Sulawesi
Coal Power Plant (PLTU) Overview
Coal-fired power plants (PLTU) in Indonesia are required to install FGD systems to meet SO2 emission standards. Hydrated lime (Ca(OH)2) is the primary sorbent in dry injection FGD, while limestone is used in wet scrubber systems. PT WEU supplies both products meeting PLTU specifications in Eastern Indonesia.
Products Used
Sorbent utama sistem FGD-DSI untuk absorpsi SO2 dari gas buang batu bara
Sorbent sistem FGD wet scrubber — dikonversi menjadi slurry CaCO3
Role of Limestone / CaCO3 in Coal Power Plant (PLTU)
In dry sorbent injection (DSI) FGD systems, hydrated lime is injected into flue gas duct before the particulate collector. Ca(OH)2 reacts with SO2 to form CaSO3 captured in bag filters. SO2 removal efficiency reaches 70–90% depending on stoichiometric ratio. Fineness of 325 mesh (>95% passing) is key to reaction effectiveness.
Technical Requirements
| Parameter | Value / Standard |
|---|---|
| Ca(OH)2 Minimum | > 92% |
| Kehalusan 325 Mesh | > 95% passing |
| Moisture Content | < 1% |
| MgO Maksimum | < 0.5% |
| Reaktivitas pH | pH slurry > 12 |
| Bulk Density | 0.45–0.55 g/ml |
Process Integration
- 1
Penerimaan Kapur Padam
Diterima dalam jumbo bag 1.000kg atau silo bulk, disimpan di storage kering kedap udara.
- 2
Persiapan Sistem Injeksi
Kapur padam dimasukkan ke pneumatic conveying system menuju injection lance di duct.
- 3
Gas Conditioning
Gas buang dikondisikan ke suhu optimal 135–150°C untuk reaksi sorbent maksimal.
- 4
Injeksi DSI
Ca(OH)2 diinjeksikan ke gas stream dengan rasio Ca/S = 2–3 untuk efisiensi removal 70–90%.
- 5
Penangkapan Reaksi Produk
Partikel CaSO3 dan CaSO4 ditangkap oleh baghouse filter atau ESP.
Industry Pain Points
Regulasi KLHK mensyaratkan emisi SO2 <550 mg/Nm3 — pelanggas yang tidak comply terancam sanksi besar
Kehalusan kapur padam tidak memenuhi 325 mesh menurunkan efisiensi SO2 removal dan meningkatkan konsumsi sorbent
Keterlambatan pasokan menyebabkan PLTU beroperasi di bawah kapasitas atau menggunakan sorbent darurat berkualitas rendah
Kapur padam dengan moisture >1% menggumpal dalam conveying system dan mengganggu sistem injeksi pneumatik
