Abstract

Limbah padat resin yang dihasilkan oleh PT. Batu Penggal Chemical Industry dari tahun 2001–2006 adalah sebesar 40 ton. Diperkirakan hingga tahun 2008 jumlah tersebut akan bertambah menjadi 56 ton apabila tidak dilakukan penanganan yang baik. Tujuan penelitian ini adalah untuk mengkaji pemanfaatan limbah padat resin tersebut sehingga tidak menimbulkan masalah bagi lingkungan.

Dalam penelitian ini, limbah padat resin dicampur dengan batubara, kemudian diukur nilai kalornya menggunakan alat bomb calorimeter. Persentase limbah padat resin terhadap batubara adalah 0%, 5%, 10%, 15%, 20%, dan 25%. Selanjutnya, dilakukan proses pembakaran dalam sebuah tungku (furnace). Gas hasil pembakaran seperti SO₂, NOₓ, CO, dan CO₂ diukur nilai emisinya, sedangkan abu sisa pembakaran dianalisis komposisinya.

Dari hasil penelitian diperoleh nilai kalor campuran batubara dan limbah padat resin sebesar 6.225, 6.193, 6.016, 5.960, 5.520, dan 5.274 cal/g. Emisi yang dihasilkan terdiri atas gas SO₂ sebesar 851, 725, 551, 250, 160, dan 130 mg/m³; gas NOₓ sebesar 593, 488, 382, 218, 219, dan 290 mg/m³; gas CO sebesar 336, 230, 62, 65, 87, dan 117 ppm; serta gas CO₂ sebesar 13.000, 10.000, 4.000, 4.000, 5.000, dan 7.000 ppm. Konsentrasi penambahan limbah padat resin yang terbaik adalah 15%. Komposisi abu sisa pembakaran terdiri dari 88,75% oksida SiO₂, Al₂O₃, dan Fe₂O₃. Limbah padat resin sebesar 56 ton akan habis dimanfaatkan sebagai bahan bakar boiler dalam waktu 350 hari dan diperoleh penghematan biaya sebesar Rp30.492.000,00/tahun.

Solid resin waste generated by PT. Batu Penggal Chemical Industry from 2001 to 2006 amounted to 40 tons. It was estimated that by 2008, the amount would increase to 56 tons if proper handling was not implemented. The objective of this research was to study the utilization of solid resin waste so that it would not cause environmental problems.
In this research, solid resin waste was mixed with coal, and its calorific value was measured using a bomb calorimeter. The percentages of solid resin waste added to the coal were 0%, 5%, 10%, 15%, 20%, and 25%. The mixtures were then combusted in a furnace. The emissions of combustion gases, including SO₂, NOₓ, CO, and CO₂, were measured, and the composition of the remaining combustion ash was analyzed.
The results showed that the calorific values of the coal and solid resin waste mixtures were 6,225, 6,193, 6,016, 5,960, 5,520, and 5,274 cal/g, respectively. The resulting gas emissions were SO₂: 851, 725, 551, 250, 160, and 130 mg/m³; NOₓ: 593, 488, 382, 218, 219, and 290 mg/m³; CO: 336, 230, 62, 65, 87, and 117 ppm; and CO₂: 13,000, 10,000, 4,000, 4,000, 5,000, and 7,000 ppm. The optimum proportion of solid resin waste addition was 15%. The composition of the remaining combustion ash consisted of 88.75% oxides of SiO₂, Al₂O₃, and Fe₂O₃. A total of 56 tons of solid resin waste could be utilized as boiler fuel within 350 days, resulting in cost savings of Rp30,492,000 per year.
