Pra Rancangan Pabrik Biodiesel dari Crude Palm Oil (CPO) dan Metanoli Kapasitas 350.000 Ton/Tahun

Biodiesel merupakan bahan bakar terbarukan yang dapat dicampur atau menggantikani bahan bakar diesel konvensional untuk pembakaran pada mesin diesel. Biodiesel dibuat menggunakan bahan baku CPO dan Metanol dengan metode Tranesterifikasi dan bantuan katalis NaOH dan asam Fosfat. Pabrik biodiesel dari crude palm oil dan metanol direncanakan didirikan di Kecamatan Meliau, Kabupaten Sanggau, Provinsi Kalimantan Barat, dibangun di atas tanah seluas 35.100 m2 dengan kapasitas produksi 350.000 ton/tahun.

Larutan kemudian diumpankan menuju dekanter (D-01) untuk memisahkan fase ringan dan fase berat, hasil bawah yang berupa fase berat diumpankan menuju unit pengolahan lanjut (UPL) sementara hasil atas yang merupakan fase ringan diumpankan ke evaporator (E-01) agar menghasilkan produk yang lebih murni. Larutan ini kemudian dipompa ke tangki penyimpanan (T-05) sebagai produk biodiesel dengan kemurnian 98,6356%. Dilihat dari sifat kimia maupun fisis bahan baku dan produk yang tidak berbahaya dan tidak beracun, proses dijalankan pada tekanan 1,5 atm dan suhu operasi tertinggi 95oC, maka pabrik ini termasuk pabrik beresiko rendah (low risk). Sehingga dapat disimpulkanibahwaipabrik ini menarik dan cukup layak dipertimbangkaniuntukididirikan.

Biodiesel is a renewable fuel that can be mixed with or replaces conventional diesel fuel for combustion in diesel engines. Biodiesel is made using CPO and methanol raw materials with the transesterification method and the help of NaOH and phosphoric acid catalysts. A biodiesel plant from crude palm oil and methanol is planned to be built in Meliau District, Sanggau Regency, West Kalimantan Province, to be built on a land area of 35,100 m2 with a production capacity of 350,000 tons/year. The process of making biodiesel begins with flowing the raw material in the form of 99% purity methanol as much as 5,422.6227 kg/hour and 48% purity sodium hydroxide catalyst to the mixing tank (M-01) to be mixed into a homogeneous one. The output from the mixing tank is flowed into the reactor (R-01) together with 44,269.7170 kg/hour of crude palm oil. The reaction was carried out in a stirred tank flow reactor (RATB). The reaction takes place at a temperature of 70oC and a pressure of 1.5 atm. The results of the reaction flow into the washing tank (TP-01) to dissolve the glycerol content in the biodiesel product. The solution is then fed to the decanter (D-01) to separate the light and heavy phases, the bottom product which is in the form of the heavy phase is fed to the advanced processing unit (UPL) while the top product which is the light phase is fed to the evaporator (E-01) to produce the product purer. This solution is then pumped into a storage tank (T-05) as a biodiesel product with a purity of 98.6356%. Judging from the chemical and physical properties of raw materials and products that are harmless and non-toxic, the process is run at a pressure of 1.5 atm and the highest operating temperature is 95oC, so this plant is a low risk factory. So it can be concluded that this factory is attractive and quite feasible to be considered for establishment.
