Abstract
Flare gas merupakan gas buang hasil proses operasi fasilitas migas yang umumnya dibakar pada sistem flare untuk alasan keselamatan dan stabilitas operasi. Praktik Flaring secara terus-menerus menyebabkan kehilangan energi, emisi gas rumah kaca, serta penurunan efisiensi pemanfaatan hidrokarbon. Penelitian ini bertujuan untuk menentukan alternatif teknologi FGR terbaik pada fasilitas pengolahan gas dengan menggunakan metode Analytical Hierarchy Process (AHP). Alternatif teknologi yang dievaluasi terdiri dari LPG Recovery, Pencampuran dengan HP Fuel Gas Recovery, dan Kompresi balik (Recycle Compression ). Penilaian dilakukan berdasarkan beberapa kriteria dan subkriteria yang meliputi aspek Cost, Time, Operability, Recovered Condensate, dan Manpower. Data diperoleh melalui studi literatur, simulasi proses menggunakan Aspen HYSYS, Technical Note perusahaan, serta Focus Group Discussion(FGD) bersama pihak teknis dan pengambil keputusan. Hasil penelitian menunjukkan bahwa alternatif Recycle Compression memiliki prioritas tertinggi dibanding alternatif lainnya. Alternatif ini dinilai unggul karena memiliki integrasi yang lebih sederhana dengan sistem eksisting , fleksibilitas operasi yang tinggi, kebutuhan modifikasi fasilitas yang lebih rendah, serta biaya investasi yang relatif lebih ekonomis. Selain meningkatkan efisiensi energi dan pemanfaatan hidrokarbon, implementasi FGR juga berpotensi mengurangi emisi karbon dan mendukung strategi Low Carbon Operation perusahaan.

Flare gas is a by-product gas generated from oil and gas processing operations that is commonly burned in flare systems for safety and operational stability purposes. Continuous Flaring practices result in energy losses, greenhouse gas emissions, and reduced hydrocarbon utilization efficiency. This study aims to determine the most suitable Flare gas recovery (FGR) technology alternative for a gas processing facility using the Analytical Hierarchy Process (AHP) method. The evaluated technology alternatives consist of LPG Recovery, Blending with HP Fuel Gas Recovery, and Recycle Compression . The assessment was carried out based on several criteria and subcriteria, including Cost, Time, Operability, Recovered Condensate, and Manpower aspects. Data were obtained through literature studies, Aspen HYSYS process simulations, company Technical Notes, and Focus Group Discussions (FGD) involving technical personnel and decision makers. The results indicate that the Recycle Compression alternative achieved the highest priority among the evaluated alternatives. This option was considered superior due to its simpler integration with the eksisting system, high operational flexibility, lower facility modification requirements, and relatively more economical investment Cost. In addition to improving energy efficiency and hydrocarbon utilization, the implementation of FGR also has the potential to reduce carbon emissions and support the company’s low-carbon operation strategy.
