Abstract

Pemanasan global merupakan kenaikan suhu udara rata-rata global pada permukaan bumi. Pemanasan global disebabkan terutama oleh karbon dioksida (CO2) dan metana. Solusi yang dapat diterapkan secara cepat dan dalam skala besar adalah menggunakan teknologi Carbon Capture and Storage (CCS). Teknologi ini merupakan rangkaian kegiatan yang dimulai dari menangkap CO2 (capture) dari sumber-sumber emisi CO2 (source), kemudian mentransportasikannya ke lokasi penyimpanan CO2 di geological sink yang sesuai (sink). Pada proses CCS, proses pencocokkan (matching) antara source dan sink seringkali mengalami berbagai kendala, seperti batas kapasitas, lokasi, laju alir injeksi, dan waktu ketersediaan dari source dan sink yang tersedia. Masalah-masalah tersebut dapat diatasi oleh suatu metode, yaitu metode Pinch. Suatu permasalahan pada CCS mungkin terjadi ketika lokasi source dan sink yang ada belum tentu berada pada satu wilayah yang berdekatan (single region), sehingga dimungkinkan bahwa proses CCS dapat terjadi secara multi region dimana lokasi source dan sink berjauhan dan dengan banyak wilayah. Pengembangan studi multi region dilakukan dalam penelitian ini, yaitu dengan batasan wilayah Sumatera Selatan dan Jawa Timur dengan total 5 source dan 6 sink. Pengembangan dilakukan dengan metode pinch multi region secara transfer massa secara simultan dan transfer massa secara sequencial serta dilakukan optimisasi dengan variasi jeda waktu (Δt) 0, 5, 10 berdasarkan TAC. Hasil penelitian didapatkan pada metode pinch transfer massa secara sequencial dihasilkan % capturable CO2 paling banyak pada beda waktu 0 tahun sebesar 93,86 % daripada pengerjaan transfer massa secara simultan dengan % capturable CO2 sebesar 83,94 %. Biaya paling efisien didapatkan pada metode pinch transfer massa secara simultan dengan jeda waktu (Δt) 4,6 tahun dengan biaya Rp 2,15 Trilliun daripada pengerjaan transfer massa secara sequencial dengan (Δt) 4,5 tahun dengan biaya Rp 2,25 Triliun. Metode Linear Programming GAMS bisa menentukan utiilitas storage minimum pada CCS system akan tetapi kurang efisien. Metode pinch transfer massa secara sequencial baik digunakan jika desain lebih mengutamakan kuantitas capturable CO2 dibanding dengan segi biaya CCS. ================================================================================================= Global warming is a rise in global temperatures average on the earth's surface. Global warming is caused mainly by carbon dioxide (CO2) and methane. Solution that can be applied quickly and on a large scale is to use Carbon Capture and Storage (CCS) technology. This technology is a series of activities starting from CO2 capture of the sources of CO2 emissions (source), and then transport it to the storage of CO2 in suitable geological sink locations (sink). In the CCS process, matching between sources and sinks often face many obstacles, such as capacity limits, location, injection flow rate, and availability time from sources and sinks that available. These problems can be solved by a method, that is pinch method. A problem with CCS may occur when the source and sink located in one adjacent area (single region), so it is possible that the CCS process can occur in a multi region where the source and sink locations are far and with many regions. The development of multi region study was conducted in this study, with boundaries area of South Sumatra and East Java with a total of 5 sources and 6 sinks. The development was done by mass transfer simultaneously multi region pinch method and modified and optimized with time interval (Δt) 0, 5, 10 based on TAC. The result of this research is obtained by the pinch method of sequencial mass transfer produced % capturable CO2 at the most at time interval 0 years equal to 93,86 % than mass transfer simultaneously method with % capturable CO2 83,94 %. The most efficient cost is found in mass transfer simultaneously pinch method with time interval (Δt) of 4.6 years at a cost of Rp 2.15 trillion than sequencial mass transfer method with time interval (Δt) of 4.5 years at a cost Rp 2.25 trillion. The Linear Programming GAMS method can determine the minimum storage utility in the CCS system but it is less efficient. The pinch sequencial mass transfer method is best used if the design prefers the quantity of capturable CO2 compared to the cost side of CCS.
