Abstract

Benzene dengan rumus kimia C6H6 merupakan senyawa yang volatile, tidak berwarna dan mudah terbakar. Umumnya benzene banyak digunakan sebagai bahan baku dalam sintesis dari styrene, phenol, cyclohexane, aniline, alkylbenzene, chlorobenzene dan produk lain yang digunakan dalam proses produksi obat, insektisida dan plastic. Pabrik Benzene ini mempunyai kapasitas sebesar 70000 ton/tahun. Lokasi pendirian pabrik direncanakan di Cilegon, Banten. Pabrik menggunakan bahan baku Toluene dan Hydrogen. Bahan baku yang digunakan yaitu Toluene sebesar 25071.97 kg/jam dan hydrogen sebesar 136.2607 kg/hari.Proses produksi benzene dilakukan dengan proses Hydrodealkilasi, dimana feed berupa toluene direaksikan dengan hydrogen dalam sebuah reactor, di reactor ini terjadi reaksi hydrodealkilas, reactor beroperasi pada temperature 6000C dengan tekanan 25.5 bar. Hasil keluaran dari reactor akan masuk ke separator kemudian masuk ke kolom fraksinasi untuk memisahkan benzene dengan hasil samping dari reaksi yang terjadi yaitu methane, sisa toluene yang tidak terkonversi dan xylene yang nantinya akan ditampung dalam storage tank. Kebutuhan utilitas pada pabrik benzene meliputi air pendingin sebesar 14324,30099 kg/hari, air umpan boiler sebesar 9152,9867 kg/hari, air sanitasi sebesar 36480 kg/hari, dan air kebutuhan tambahan sebesar 411,58587006 2 kg/hari. Produk utama yang dihasilkan yaitu benze dengan kemurnian 99,96%. ======================================================================================================== Benzene (C6H6) is a volatile compound, colorless and highly flammable. Generally, benzene is being used as a raw material in the synthesis of styrene, phenol, cyclohexane, aniline, alkyl benzene, chlorobenzene and can be used in the production of drugs, insecticides and plastic. Benzene can also be used as a solvent in the extraction. Benzene factory has a capacity of 70000 tons / year. Location of the factory is in Cilegon, Banten. The plant uses raw materials are Toluene and Hydrogen. The raw material used is Toluene for about 25071.97 kg / hr and hydrogen for about136.2607 kg / day. The production process is done by a Hydrodealkylation process, which toluene is reacted with hydrogen in a reactor, in this reactor occur the hydrodealkylation reaction. Before entering the reactor, feed to be heated using feed pre-heater and then feed enter to the reactor, the reactor operates at temperatures of 6000C with a pressure of 25.5 bar. The output of the reactor will enter into separator and then into the benzene column to separate benzene with the byproducts of the reaction are methane, unconverted toluene and xylene that will be accommodated in a storage tank. The utility needs of plants are 14324,30099 kg/day of cooling water, 9152,9867 kg/day of boiler feedwater, 36480 kg/day of sanitation water,and 411,58587006 2 kg/day of water process. The main products are benzene with 99.96% purity. Byproducts are methane, and xylene.
