Abstract

Salah satu pemanfaatan utama gas alam adalah untuk keperluan pemenuhan energi, seperti pengubahan gas alam menjadi Liquefied Natural Gas (LNG). Gas alam didistribusikan dengan cara diproses menjadi Liquefied Natural Gas dengan tujuan kemudahan transportasi dan pemasokan energi ke daerah-daerah terpencil. Pabrik ini rencananya didirikan di Pulau Bunyu, Kalimantan Utara untuk memasok energi di wilayah Indonesia Timur. Liquefied Natural Gas adalah gas alam yang telah melalui proses pendinginan yang memiliki kandungan methane dengan jumlah 90% mole, juga mengandung hidrokarbon berat seperti C2 hingga C4, nitrogen, sulfur dalam jumlah kecil (kurang dari 4 ppmv), dan CO2 (50 ppmv). Dalam pembuatan LNG, digunakan metode pendinginan berupa Optimized Single Mixed Refrigerant. Metode ini dinilai lebih efektif karena membutuhkan energi yang lebih sedikit pada alat compressor yang digunakan. Terdapat dua proses utama dalam pembuatan LNG yaitu pendinginan dan siklus refrigerant. Pabrik ini juga dilengkapi dengan acid gas removal serta condensate stabilization unit. Hasil dari pabrik ini merupakan LNG dengan kapasitas 0,36 MTPA dengan proyeksi keekonomian pabrik yaitu memiliki pay-out time 6,22 tahun yang mengindikasikan pabrik ini layak dibangun.

One of the main uses of natural gas is for energy needs, such as converting natural gas into Liquefied Natural Gas (LNG). One promising energy source, due to its abundance, is natural gas. The utilization and distribution of natural gas play an essential role in fulfilling energy needs. Natural gas is processed into liquefied natural gas (LNG) for easier transportation and energy supply to remote areas. This plant is planned to be established on Bunyu Island, North Kalimantan, to supply energy to Eastern Indonesia. LNG is a natural gas that has been cooled and primarily consists of methane (90% by mole) but also contains heavier hydrocarbons such as C2 to C4, nitrogen, small amounts of sulfur (less than 4 ppmv), and CO2 (50 ppmv). The LNG production process employs the Optimized Single Mixed Refrigerant method, which is considered more effective due to its lower energy requirements for compressors. There are two main processes in LNG production: liquefaction and the refrigerant cycle. The plant will also feature acid gas removal and condensate stabilization units. The output of the plant is projected to be 0.36 MTPA of LNG, with an economic projection indicating a pay-out time of 6.22 years, making the plant a viable investment.
