Abstract

Peningkatan kebutuhan energi dan aktivitas industri berbasis bahan bakar fosil menyebabkan emisi gas CO2 terus mengalami kenaikan, khususnya dari sektor pembangkit listrik tenaga uap (PLTU) batu bara. Salah satu upaya pemanfaatan emisi CO2 yang bernilai ekonomis adalah melalui konsep Carbon Capture and Utilization (CCU), yaitu pemanfaatan gas buang sebagai bahan baku proses industri. Precipitated Calcium Carbonate (PCC) merupakan produk kalsium karbonat bernilai tambah tinggi yang banyak digunakan sebagai bahan pengisi (filler) dan pelapis (coating pigment) pada industri kertas, plastik, cat, farmasi, serta material konstruksi. Dalam perancangan ini, direncanakan pembangunan pabrik PCC dengan metode karbonasi yang terintegrasi pemanfaatan gas karbondioksida (CO2) dari emisi gas buang Pembangkit Listrik Tenaga Uap (PLTU) batu bara dengan kapasitas rancangan sebesar 40.000 ton/tahun yang berlokasi di kawasan PLTU Tanjung Awar-Awar, Tuban, Jawa Timur. Bahan baku utama yang digunakan adalah kalsium oksida (CaO), air proses, dan flue gas PLTU sebagai sumber CO2. Pada kapasitas produksi tersebut, pabrik ini diperkirakan mampu memanfaatkan sekitar 17.600 ton CO2 per tahun sebagai bahan baku pembentukan CaCO3. Hasil perhitungan neraca massa serta energi menunjukan rancangan pabrik ini mampu menghasilkan produk PCC on-spec sebesar 5.066,4590 kg/jam yang telah memeuhi kualitas dan spesifikasi produk pasaran. Berdasarkan analisis ekonomi, pabrik PCC ini memiliki nilai NPV sebesar Rp 228.587.773.230, IRR sebesar 17,77%, POT selama 5,15 tahun dan BEP sebesar 40,65%, sehingga dinilai layak secara teknis maupun ekonomis untuk didirikan. Dengan demikian, pembangunan pabrik PCC berbasis pemanfaatan flue gas PLTU tidak hanya berpotensi memenuhi kebutuhan industri dalam negeri, tetapi juga mendukung pengurangan emisi CO2 melalui pemanfaatan karbon menjadi produk bernilai tambah.

The increasing demand for energy and the continued reliance on fossil-fuel-based industries have contributed significantly to the rise of carbon dioxide (CO2) emissions, particularly from coal-fired power plants. One promising approach to mitigating these emissions is through Carbon Capture and Utilization (CCU), which converts CO2 containing flue gas into value-added products. Precipitated Calcium Carbonate (PCC) is a high-value calcium carbonate product widely utilized as a filler and coating pigment in the paper, plastics, paint, pharmaceutical, and construction materials industries. This study presents the design of a PCC plant employing a carbonation process integrated with the utilization of CO2 from the flue gas emissions of the Tanjung Awar-Awar coal-fired power plant in Tuban, East Java. The plant is designed with a production capacity of 40,000 metric tons per year using calcium oxide (CaO), process water, and flue gas as the primary raw materials. At the proposed capacity, the plant is estimated to utilize approximately 17,600 metric tons of CO2 annually for PCC production. Mass and energy balance calculations indicate that the plant is capable of producing 5,066.4590 kg/h of PCC that meets the required product specifications and market quality standards. Economic analysis shows that the proposed plant has a Net Present Value (NPV) of Rp Rp 228.587.773.230 with an Internal Rate of Return (IRR) of 17,77%, a Pay Out Time (POT) of 5,15 years, and a Break Even Point (BEP) of 40,65%, indicating favorable economic feasibility. Therefore, the proposed PCC plant is considered technically feasible, economically profitable, and environmentally beneficial due to its contribution to reducing industrial CO2 emissions through flue gas utilization.
