Abstract

Seiring dengan majunya teknologi diiringi dengan kebutuhan energi yang semakin tinggi. Di Indonesia sendiri pembangkit listrik masih didominasi oleh pembangkit berbahan bakar fosil yang mengakibatkan meningkatnya emisi gas khususnya gas CO2 sehingga perlunya upaya untuk mengurangi gas CO2. Di sisi lain, industri di Indonesia khususnya industri kaca, farmasi, dan lain-lain meningkatkan kebutuhan akan Potassium Carbonate yang saat ini masih bergantung pada impor dan cenderung meningkat untuk seiring waktu. Sehingga pabrik Potassium Carbonate menjadi salah satu kebutuhan untuk memenuhi permintaan tersebut. Dengan alasan tersebut penulis mengkaji kelayakan pembangunan pabrik Potassium Carbonate di Paiton, Probolinggo, Indonesia dengan bahan baku flue gas atau gas buang dari PLTU Paiton Unit 3 dan KOH. Pengkajian mencakup proses, studi bahaya (HAZOP) awal, spesifikasi alat dan juga ekonomi. Pabrik yang dirancang memiliki kapasitas maksimal 7.500 ton/tahun. Periode konstruksi diperkirakan selesai pada 2 tahun dengan umur ekonomi pabrik 20 tahun. Dari studi kelayakan menunjukkan jika pabrik layak didirikan dengan proyeksi tingkat pengembalian internal (IRR) sebesar 26%. Pabrik ini diharapkan dapat memenuhi kebutuhan Potassium Carbonate nasional dan juga membantu mengatasi permasalahan peningkatan emisi gas khususnya CO2.

Along with the advancement of technology and the increasing demand for energy, electricity generation in Indonesia is still dominated by fossil fuel-based power plants. This has led to an increase in gas emissions, particularly CO2, necessitating efforts to reduce CO2 emissions. On the other hand, industries in Indonesia, particularly glass and pharmaceutical industries, have seen a rising demand for Potassium Carbonate, which is currently heavily reliant on imports and tends to increase over time. Therefore, establishing a Potassium Carbonate plant is essential to meet this demand. For these reasons, the author examines the feasibility of building a Potassium Carbonate plant in Paiton, Probolinggo, Indonesia, using flue gas from Paiton Power Plant Unit 3 and KOH as raw materials. The study covers processes, an initial hazard and operability study (HAZOP), equipment specifications, and economic analysis. The proposed plant is designed to have a capacity of 7,500 tons per year at full capacity. The construction period is estimated to be completed within two years, with an economic lifespan of 20 years. The feasibility study indicates that the plant is viable, with a projected internal rate of return (IRR) of 26%. This plant is expected to meet national Potassium Carbonate needs and help address the issue of increasing gas emissions, particularly CO2.
