Abstract

Pra rancangan pabrik kimia Propilen berbahan baku propana dengan kapasitas 185.000 ton/tahun akan dibangun di Kawasan Industri Krakatau di Cilegon, Provinsi Jawa Barat. Bahan baku propana diperoleh dari PT Aneka Gas Industri yang terletak di Provinsi Jawa Barat dengan kebutuhan sebesar 27.474 kg/jam. Pabrik ini dirancang beroperasi secara kontinyu selama 24 jam per hari dan 330 hari per tahun. Proses produksi yang digunakan adalah proses dehidrogenasi propana pada suhu 600°C dan 1 atm yang direaksikan di Reaktor Fix Bed Multitube Tank Reactor. Reaksi berlangsung secara endotermis dengan konversi optimum sebesar 90%. Campuran gas keluaran reaktor akan dialirkan kedalam cooler dan kompressor untuk menurunkan suhu dan menaikkan tekanan gas. Selanjutnya, campuran gas akan dialirkan menuju distilasi untuk memisahkan fase berat berupa propana dan fase ringan berupa propilen, hidrogen, dan nitrogen. Aliran keluaran atas destilasi yakni senyawa propilen akan di kondensasikan dan disimpan di tangki penyimpanan produk, sedangkan hidrogen dan nitrogen berupa fasa gas disimpan di tangki penyimpanan hidrogen. Dalam operasionalnya, proses produksi perlu didukung dengan adanya unit utilitas yang menyediakan air untuk proses, air pendingin, dan air umpan boiler sebanyak 120.847,4 kg/jam, kemudian kebutuhan steam sebesar 13.248 kg/jam, dan kebutuhan listrik sebesar 220 kWh. Pabrik ini membutuhkann investasi sebesar $38.735.590,26 untuk dapat didirikan dengan analisis profitabilitas dievaluasi melalui parameter-parameter seperti BEP dan DCFR dengan nilai masing-masing sebesar 23% dan 55,50%. Berdasarkan tinjauan parameter-parameter dari segi teknis dan ekonomis, Pabrik Propilen berbahan baku Propana dengan kapasitas 185.000 ton/tahun layak untuk dikaji lebih lanjut. Kata Kunci: Propilen, Cilegon, Dehidrogenasi
