ABSTRAK Suatu sistem kompresi dibutuhkan untuk menaikkan tekanan sumur produksi gasyang mengalami penurunan secara alami. Sistem kompresi yang akan dipasangterdiri atas 3 train kompresor paralel berpenggerak turbin gas. Sesuai kondisiproses dan spesifikasi kompresor ditetapkan bahwa hanya 2 kompresor yang akandioperasikan secara paralel selama total 8 tahun operasi. Hasil evaluasi ditemukanbahwa masing-masing kompresor adalah non identik ditinjau dari kurva kinerjayang berbeda satu sama lain. Untuk mengetahui 2 kompresor paralel mana yangmenghasilkan efisiensi sistem paling tinggi selama total masa operasi makadilakukan simulasi nilai efisiensi sistem terhadap penurunan tekanan gas umpan.Efisiensi sistem kompresi diidentifikasi dengan parameter yang dinamakanS-Ratio. Hasil simulasi antar kombinasi kompresor dibandingkan untukmengetahui peringkat kinerja kompresor. Berdasarkan peringkat kinerja dan aspekperawatan turbin gas kompresor, terdapat 2 opsi urutan pengoperasian kompresordimana perbedaan kedua opsi tersebut hanya pada urutan pengoperasian di tahunke 4 dan ke 5 dan urutan pelaksanaan overhaul. Setelah penentuan opsi urutanpengoperasian, kemudian dicari nilai beban alir optimal melalui pendekatanoptimalisasi. Beban alir optimal akan menghasilkan power total kompresoroptimal. Nilai penghematan biaya bahan bakar turbin gas diperoleh melaluipengurangan biaya dengan pembebanan aliran merata dan dengan pembebananaliran optimal. Kemudian ditinjau dari prosentase penghematan biaya terhadaptotal biaya energi menghasilkan nilai yang kurang signifikan. ABSTRACT A compression system is required to raise the gas production well pressure whichdecrease naturally. Compression system consist of three parallel compressor trainsdriven by gas turbines. According to the process requirement and compressorcapability, it is decided that only 2 compressors to be operated in parallel for totalof operation lifetime. The evaluation results found that each compressor is nonidentical in terms of performance curves. To know which compressorcombination will generate the highest system efficiency over the total operationperiod then process simulation which comparing system efficiency to feed gaspressure is conducted. The system efficiency is identified by a parameter calledthe S-Ratio. The simulation results among compressor combinations are thencompared to determine the performance rating of the compressor. Ranked byperformance and maintenance aspects of gas turbine compressors, there are twooptions for the compressor operation sequence where the differences betweenboth options are on the operation order in the 4th and 5th year, and the executionorder of the engine overhaul. After operation sequence is determined, thenoptimal load distribution values is analysed through the optimization approachwhere optimal load flow will produce optimal compressor total poweraccordingly. The cost saving value is obtained by deducting cost generated byequal load flow and cost by optimal load flow. Furthermore, its cost savingpercentage compared total energy cost is insignificant. |
