Pra Desain Pabrik Metanol Dari Bambu

Menurut Kementerian Lingkungan Hidup dan Kehutanan Indonesia, memiliki 2,1 juta hektar hutan bambu. Sebagai salah satu bahan terbarukan, bambu dapat dikembangkan sebagai bahan baku metanol untuk kemudian menjadi syngas, bahan bakar, atau kimia industri lain. Untuk mengolah bambu menjadi metanol, diperlukan dua tahapan yaitu pembentukan syngas dan pembentukan metanol. Teknologi yang digunakan untuk sintesa syngas adalah dual fluidized bed reactor yang diadaptasi dari paten milik TU Vienna, sementara untuk sintesa metanol digunakan lisensor milik Johnson Matthey. Kondisi operasi yang digunakan untuk gasifikasi adalah suhu 900oC dengan tekanan atmosferik, sementara sintesa metanol pada suhu 220oC dengan tekanan 50 bar. Pabrik direncanakan beroperasi pada tahun 2022 yang berlokasi di Jembrana, Bali. Kapasitas pabrik metanol sebesar 73,15 kiloton per tahun dan beroperasi secara kontinyu selama 24 jam/hari dengan waktu produksi 330 hari/tahun. Berdasarkan analisis ekonomi, laju pengembalian modal (IRR) pabrik ini sebesar 19,2% pada tingkat bunga per tahun 9,95%. Waktu pengembalian modal (POT) adalah 7 tahun dan titik impas (BEP) sebesar 41,62%.=========================================================================================================== Based on Ministry of Environment and Forestry, Indonesia owns 2.1 million hectares of bamboo forest. As one of the renewable energies, bamboo can be utilized as methanol raw material and processed to be synthetic gas, fuel, or other chemical components. Converting bamboo to methanol needs two processes, syngas synthesis and methanol synthesis.
