Abstract

Minyak kelapa sawit (CPO) saat ini adalah sumber minyak nabati terbesar di dunia. Menurut laporan oil world pada tahun 2011, minyak kelapa sawit memberikan andil sekitar 27% atau 46 juta ton terhadap total minyak nabati di dunia. Dari produksi CPO menghasilkan limbah cair (Palm Oil Mill Effluent/POME) sebanyak 3 ton, maka direncanakan pembangunan Pabrik Biogas dari Limbah Cair Pabrik Kelapa Sawit di Kalimantan Barat. Kapasitas pabrik 7.285.703 ton biogas/tahun. Proses produksi biogas dari POME ada tiga tahap, yaitu tahap netralisasi, tahap fermentasi, dan tahap pemurnian. Pabrik ini direncanakan beroperasi secara kontinyu selama 330 hari/tahun dengan basis 24 jam/hari. Bahan baku POME yang dibutuhkan 237600 ton/tahun. Pada pabrik biogas ini, dilakukan optimasi tekanan pada alat water scrubber dari bertekanan 10 atm diturunkan menjadi 3 atm. Dari hasil optimasi dihasilkan kadar CH4 96,52%, CO2 1,81%, Nitrogen 0,6%, Hidrogen 0,47%, dan sisanya adalah H2O sebesar 0,6%. Berdasarkan analisa kelayakan ekonomi, pabrik biogas dengan kapasitas 7.285.703 ton/tahun telah layak untuk didirikan dengan NPV, IRR, POT dan BEP yang diperoleh sebesar Rp175,356,857,463; 25,95%; 4,78 tahun dan 20.07%.

Palm oil (CPO) is currently the largest source of vegetable oil in the world. According to the oil world report in 2011, palm oil contributed about 27% or 46 million tons of the total vegetable oil in the world. From the production of CPO to produce liquid waste (Palm Oil Mill Effluent / POME) as much as 3 tons, it is planned to build a Biogas Plant from Palm Oil Mill Liquid Waste in West Kalimantan. The factory capacity is 7,285,703 tons of biogas/year. The biogas production process from POME has three stages, namely the neutralization stage, the fermentation stage, and the purification stage. This plant is planned to operate continuously for 330 days/year on a 24 hour/day basis. The required POME raw material is 237600 tons/year. In this biogas plant, the pressure optimization of the water scrubber was carried out from a pressure of 10 atm down to 3 atm. From the optimization results, the levels of CH4 are 96.52%, CO2 is 1.81%, Nitrogen is 0.6%, Hydrogen is 0.47%, and the rest is 0.6% H2O. Based on the economic feasibility analysis, a biogas plant with a capacity of 7,285,703 tons/year has been feasible to be established with NPV, IRR, POT and BEP obtained in the amount of Rp. 175,356,857,463; 25.95%; 4.78 years and 20.07%.
