Abstract

Indonesia tengah giat melakukan program pengembangan tol laut. Program tersebut akan menambah jumlah produksi dan penggunaan kapal secara signifikan. Hal ini akan berimbas pada kebutuhan bahan bakar yang semakin meningkat. Gas alam merupakan salah satu sumber energi alternatif yang dapat menggantikan minyak bumi yang jumlahnya cenderung menipis. Salah satu contoh gas alam yang dapat digunakan sebagai bahan bakar alternatif di kapal adalah Liquified Natural Gas (LNG). Pada tugas akhir ini dilakukan perencanaan untuk fasilitas pencairan gas alam. Metode refrigrasi cascade digunakan dalam proses pencairan tersebut. Pada metode ini dilikukan desain process flow diagram (PFD) hingga didapatkan data untuk melakukan perhitungan mesin pendingin. Berdasarkan hasil perhitungan, untuk memenuhi kebutuhan 10 MMCFD ditentukan variabel kontrol 1 bar, 3 bar, 7 bar dan 20 bar. Dari setiap variabel kontrol tersebut diperlukan total daya 1453,7 kw ; 978,25 kw; 1044,02 kw; 1355,20 kw dengan kapasitas suplai gas 8750 kg/h ====================================================================================================== Indonesia develops sea toll program. It will increase industry production and shipping significantly. Comes along with the needs of fuel. Natural gas is an alternative to reduce fuel oil usage due to continously decreasing of its amount. Liquefied natural gas (LNG) is one of an example of alternative marine fuel. This bachelor thesis constructs natural gas liquefaction facility. Cascade refrigeration method applied inside that system. Inside, process flow diagram diagram (PFD) is to be designed comes with the obtained required data for refrigeration system calculation. The result from the calculation shown the required 10 mmscfd in control variable of 1 bar, 3 bar, 7 bar, and 20 bar. In each control variable needs total power 1,453.7 kW; 978.25 kW; 1,044.02 kW; 1,355.20 kW with gas supply capacity 8,750 kg/h
