Abstract

The Natuna Gas Field has a potential gas reserve of 222 TCF, but this gas field has a very high CO, content of up to 71%. The high composition of CO, content and its location, which is too far from the market, causes the best option to use the Natuna's gas by converting it to liquid. Dimethyl Ether (DME) is a choice of liquid products that have a good potential as alternative energy for household LPG. A more in-depth study of the options for using the Natuna's gas into DME product via direct process was carried out in this study. The methodology used is initiated by determining the type of facilities needed and then conducting a process simulation to determine the mass balance, energy balance, and design of the equipment used. Process simulation and economic simulation show that the Natuna Gas Field is technically feasible to be developed into a DME product with a capacity of 1,800 MMSCFD, resulting in 21,245 MT/day DME. Upstream and downstream integration economic scheme produces a better economic result (ROI: 6.34%) compared to an upstream economic scheme (ROI: 0.63%). Apart from that, tax incentives on the downstream scheme can increase the project economy, and the scenario of tax holiday is the most beneficial for developers and the government.

Abstract

Bahan Bakar Minyak (BBM) masih menjadi sumber energi utama di Indonesia hingga saatini. Namum demikian, tingginya harga minyak bumi dalam beberapa tahun terakhir telah mendorongkonsumen BBM mencari sumber energi alternatif yang lebih murah. Di tengah ketidakstabilandan tingginya harga BBM, gas bumi muncul sebagai salah satu sumber energi alternatif. Selainharganya lebih murah, gas bumi lebih ramah lingkungan. Sejauh ini, kendala utama pemanfaatangas bumi di Indonesia adalah ketersediaan infrastruktur transportasi gas bumi yang belum memadai.Jaringan pipa transmisi dan distribusi yang selama ini digunakan sebagai moda transportasi utamagas bumi di Indonesia memiliki beberapa keterbatasan seperti jarak sumber gas ke konsumencukup jauh sehingga secara teknis maupun keekonomian tidak memungkinkan dikembangkanjaringan pipa. Untuk mengatasi hal itu diperlukan suatu solusi alternatif yang ekonomis untukmenyalurkan gas bumi ke sektor konsumen yang membutuhkan. Salah satu solusi untuk mengatasikendala tersebut adalah dengan menggunakan teknologi Compressed Natural Gas (CNG) yangsaat ini telah digunakan secara luas di beberapa negara seperti Amerika Serikat, India, Cina,Thailand dan lain-lain. Teknologi ini diharapkan mampu mengakomodasi kendala transportasi gasbumi ke konsumen-konsumen yang tidak terjangkau oleh infrastruktur jaringan pipa gas bumi.
