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

Penetapan cadangan strategis perlu dirumuskan mengingat ketersediaan bahan baku kilang minyak mentah untuk keperluan Refi nery Unit (RU) di beberapa kilang di Indonesia sering tidak menentu. Oleh karenanya diperlukan fasilitas penyimpanan sumber bahan baku untuk kilang minyak tersebut, agar kilang minyak yang ada di Indonesia dapat berfungsi dengan optimal dan menghasilkan produk keluaran dengan harga yang lebih ekonomis. Untuk itu dilakukan penelitian ini sebagai bahan masukan pemerintah dalam menetapkan besaran, lokasi dan pengembangan infrastruktur yang dapat mendukung penerapan cadangan strategis. Pada penelitian ini dilakukan analisis cost (biaya) yang dikeluarkan dalam mengembangkan cadangan strategis, dan benefi t (manfaat) yang terdiri dari direct benefi t dan indirect benefi t. Analisis secara keseluruhan menggunakan Benefi t Cost Rasio(BCR) untuk mengetahui besaran keuntungan/kerugian serta kelayakan pengembangan/cadangan strategis. Berdasarkan hasil analisis dihasilkan bahwa prioritas pengembangan cadangan strategis yang paling siap/layak dikembangkan adalah RU VII Kasim dengan nilai BCR indirect sampai 2.02, selanjutnya RU 3 Plaju, RU 5 Balikpapan, RU 6 Balongan, RU 2 Dumai, dan RU 4 Cilacap.
