In meeting the world energy needs, natural gas is one of the fuel options because it has advantages that are cleaner than coal and petroleum. To facilitate the transportation process, natural gas is liquefied at the LNG plant. One of the LNG refineries to be built is the Cepu Mini LNG refinery plant with a capacity of 9 MMSCFD whose gas comes from the Gundih Gas Plant and JTB. <br /> <br /> Before the development is carried out, first step that has to be done is the feasibility study, especially in the technical and financial aspects. The engineering aspect will issue the design process and conceptual layout of the refinery so products that can be produced are in accordance with the standard, while financial aspects will be assessed based on investment feasibility criteria. <br /> <br /> The process unit to be used at the Cepu Mini LNG refinery plant is the Acid Gas Removal Unit, Dehydration Gas Unit, Gas Cooling Unit, and Gas Liquefaction Unit. Based on simulation by Aspen HYSYS v8.8, obtained LNG products with the Wobbe Index 144.895 kWh/m3 and H2O content of 0.092 ppm, CO2 of 38.79 ppm, and H2S of 2.187 ppm which conform to specifications. This Mini LNG Plant has an investment cost of $50,160,027, operating cost of $5,671,172/year, and Cost of Production of $3.641/MMBtu. Criteria of Internal Rate of Return, Net Present Value and Payback Period produced are 16.12%, $19,515,048, and 7.41 years. Thus, the Cepu Mini LNG refinery plant is declared feasible in the technical and financial aspects.
