Abstract

Oil production from the extraction of Buton Asphalt (Asbuton) becomes an attractive bitumen to study considering that the use of Asbuton is currently still relatively limited for asphalt needs with absorption of only 0.9% of national asphalt needs, of course this is a contradiction considering Asbuton deposits reach 667 million tons. Another factor is the high price of crude oil encouraging the use of bitumen as an alternative to crude oil, especially heavy crude oil. Bitumen reserves contained in Asbuton are capable of meeting oil refinery needs of 50,000 BOPD or the equivalent of 4.3% of domestic refinery capacity for a period of 20 years. There are two options for Bitumen production from Asbuton, namely all production comes from open pit mining or a combination of production from open pit mining (40%) and in situ extraction (60%). The techno-economic analysis was prepared with the assumption that the Asbuton production area is part of the Oil and Gas Working Area with a Cost Recovery Production Sharing Contract (PSC) scheme. The development of Bitumen production from Asbuton provides feasible economic indicators with NPV = $ 973 million and IRR = 15.2%. During the contract period, the government received revenue of $ 12.0 billion and the contractor $ 14.6 billion. This economic feasibility study is expected to enrich further our understanding over Buton asphalt utilization in support of crude oil production in the future

Abstract

Aditif penurun titik tuang minyak mentah umumnya dibuat dari bahan petrokimia yang merupakan sumber tidak terbarukan. Oleh sebab itu, ketersediaan aditif dari sumber terbarukan sangat diperlukan untuk mengurangi ketergantungan terhadap bahan petrokimia. Penelitian ini bertujuan untuk mendapatkan aditif penurun titik tuang minyak mentah berbahan dasar Lateks Karet Alam. Pembuatan aditif ini menggunakan reaksi kopolimerisasi isoprena yang terkandung di dalam Lateks Karet Alam dengan monomer anhidrida maleat dan monomer stirena dengan rasio 70:20:10 (b/b), 70:15:15 (b/b), dan 70:10:20 (b/b) hingga terbentuk kopolimer. Kopolimer tersebut kemudian ditambahkan ke dalam dua jenis minyak mentah pada variasi konsentrasi 1000 ppm, 5000 ppm dan 10.000 ppm. Analisis yang dilakukan meliputi uji karakteristik lateks karet alam, uji fisika dan kimia minyak mentah, serta uji titik tuang minyak mentah sebelum dan sesudah penambahan kopolimer. Hasil penelitian menunjukkan bahwa penurunan pour point maksimum terjadi pada penambahan kopolimer 10.000 ppm dengan rasio Lateks Karet Alam, anhidrida maleat, dan stirena adalah 70:20:10. Pada rasio dan konsentrasi ini, kopolimer mampu menurunkan titik tuang minyak mentah dari 45°C menjadi 33°C
