Abstract

Pada saat ini Indonesia memiliki powerplants yang tersebar luas di berbagai daerah baik milik PLN ataupun perusahaan swasta (Non PLN). Setiap perusahaan akan mengemisikan CO2 dari hasil pembakaran powerplant. CO2 tersebut dapat digunakan untuk enhanced oil recovery (EOR). CO2 EOR merupakan suatu proses injeksi CO2 ke dalam suatu sumur injeksi untuk meningkatkan produksi minyak khususnya pada sumur tahap tersier. Potensi CO2 EOR ini dapat diterapkan di Indonesia mengingat terdapat beberapa powerplant dan perusahaan minyak khususnya di Jawa Timur. Akan tetapi untuk mengaplikasikannya membutuhkan biaya (cost) yang bergantung pada jumlah CO2 yang dialirkan dan jarak tempuh antara sumber CO2 ke sumur injeksi, sehingga dibutuhkan optimisasi agar diperoleh cost yang minimum. Cost terdiri CAPEX dan OPEX atas CO2 captured (PLTU dan PLTG), pipa dan kompresor. Dalam hal ini variabel optimasi yaitu jalur perpipaan, diameter pipa, dan mass flowrate CO2 Captured. Lokasi sources (powerplants) dan sinks (perusahaan minyak) berada di Jawa Timur dengan jumlah source dan sink masing-masing sebesar 7, dengan kapasitas dan koordinat yang berbeda-beda. Hasil optimisasi didapat jalur distribusi CO2 dari source 1,3,4,dan 7, karena jaraknya yang relatif lebih dekat terhadap sejumlah sink. Source 1 men-supply sebesar 57,934 kton, source 3 sebesar 6,965 kton, source 4 sebesar 16,167 kton, dan source 7 sebesar 1,597 kton. Masing-masing diameter yaitu sebesar 1 inchi. Nilai CAPEX minimum setiap source dalam mendistribusikan CO2 captured yaitu source 1 sebesar US$1.721.691, source 3 US$247.066, source 4 US$797.111, dan source 7 US$352.359. Nilai OPEX minimum setiap source dalam mendistribusikan CO2 Captured yaitu Source 1 sebesar US$1.243.876, Source 3 US$202.927, Source 4 US$660.846, dan Source 7 US$335.888 ================================================================================================= On this time, Indonesia have powerplants that spread in some area, either PLN or private company (Non PLN). Every company will emit CO2 from result of powerplant’s burning. These CO2 can be used for enhanced oil recovery (EOR). CO2 EOR is a process of injecting CO2 to an injection well for enhance oil production especially at well in tersier stage. CO2 EOR is potensial to install in Indonesia, remembered there are a lot of powerplants and oil companies especially in East Java. But to apply it, need cost that depend on amount of CO2 which streamed and mileage between CO2’s source to injection well, so that required optimization to provided minimum cost. Cost composed as CAPEX and OPEX on CO2 captured (steam powerplant and gas powerplants), pipe, and compressor. In this case the optimization variables are pipeline path, pipe diameter, and CO2 captured mass flowrate. Location of sources (powerplants) and sinks (oil company) are in East Java with amount of each are 7, with different both capacity and coordinate. The result of optimization provided a path which distribute CO2 from source 1,2,3, and 7 because they distance relatively closer to amount of sink. Source 1 supply about 57,934 kton, source 3 supply about 6,965 kton, source 4 supply about 16,167 kton, and source 7 supply about 1,597 kton. Each diameter is about 1 inch.. Minimum CAPEX value all source in distributing CO2 captured are source 1 about US$1.721.691, source 3 about US$247.066, source 4 about US$797.111, and source 7 about US$352.359. Minimum OPEX value all source in distributing CO2 captured are source 1 about US$1.243.876, source 3 about US$202.927, source 4 about US$660.846, and source 7 about US$335.888
