Abstract

Seiring dengan bertambahnya jumlah penduduk di Indonesia maka tidak dapat dihindari bahwa kebutuhan dasar penduduk juga meningkat, salah satunya adalah kebutuhan plastik. Salah satu bahan dasar plastik adalah polyethylene yang dimana bahan ini terbuat dari ethylene. Oleh karena itu, pemerintah melalui sasaran jangka panjang peraturan menteri perindustrian tahun 2015-2025 mengarahkan untuk peningkatan produksi ethylene dalam negeri dari 750 KTPA menjadi 1600 KTPA. Namun, Indonesia hanya memiliki satu pabrik ethylene oleh Chandra Asri Petrochemical dengan kapasitas 820 KTPA. Sehingga dibutuhkan pabrik dengan tujuan memenuhi kebutuhan dalam negeri. Lisensi teknologi yang digunakan yaitu Lummus Technology by Mcdermott Technology. Kondisi operasi yang digunakan yaitu temperatur 850oC dan tekanan 1.4 bar pada proses cracking naptha. Proses pembuatan ethylene dari naptha terdiri dari hot section, cold section, dan hydrogen purification section. Untuk hot section, terdapat 2 proses utama yaitu cracking dan purifikasi gas dari H2S dan CO2. Pada cold section, terdapat 2 proses utama yaitu acetylene conversion dan ethylene prufication. Serta pada hydrogen purification terdapat purifikasi gas hidrogen hingga kemurnian >99.95%. Pabrik direncanakan beroperasi pada tahun 2022 yang berlokasi pada kawasan Cilegon, Banten. Kapasitas pabrik ethylene sebesar 300 KTPA dan beroperasi secara kontinyu selama 24 jam/hari dengan waktu produksi 330 hari/tahun. Berdasarkan analisis ekonomi untuk kapasitas 300 KTPA, laju pengembalian modal (IRR) pabrik ini sebesar 23.2% pada tingkat suku bunga per-tahun 9.95%. Sedangkan untuk waktu pengembalian modal (POT) adalah 9.25 tahun dan titik impas (BEP) sebesar 21,29%. ========================================================= With the growing amount of people living in Indoneisa, it is inevitable that the basic needs of these people also increase, including the need of plastic. One of the basic ingredients in making plastic is Polyethylene which is made from Ethylene. Because of this, the government increase the production of Ethylene that is made by Indonesia from 750 KTPA to 1600 KTPA and this is written in the subject of long term from 2015-2025 in Indonesia’s Industrial Minister Regulation. However, Indonesia only have one Ethylene producing factory which is Chandra Asri Petrochemical with the capacity of only 820 KTPA. Therefore, it is needed to have an Ethylene producing factory in order to fulfill the need in Indonesia. License Technology that is used is from Lummus Technology by Mcdermott Technology. Operating Condition that is used is 850oC and pressure of 1,4 bar in the Naptha Cracking Process. The process of making Ethylene from Naptha are composed by : Hot Section, Cold Section and Hydrogen Purification Section. For Hot Section, there are 2 main processes which are Cracking and Gas Purification from H2S and CO2. In Cold Section, there are two main processes which are Acetylene Conversion and Ethylene Purification. And in Hydrogen Purification there is a process to purify Hydrogen gasses until purity of >99,95% is obtained. This Factory is planned to be operated on 2022 and located in the area of Cilegon, Banten. The capacity of the Ethylene producing Factory is 300 KTPA and operated continuously for 24 hours / day with the production time of 330 day/year. Based on the Economic Analysis for the capacity of 300 KTPA, the Internal Rate of Return is 23,2% with bank rate per year of 9,95%. For the Pay Out Time is 9,25 year and for the Break Even Point is 21,29%.
