Pra Rancangan Pabrik Pencairan Batubara menjadi Syncrude N-Pentane dengan Kapasitas 10.000 Ton / Tahun

Abstract

Coal reserve in South Kalimantan amount to more than 5 billion ton. And the coal productionjust 54 million tonper year. Because ofits, coal in South Kalimantan will finished 100 year again. Coal price in Kalimantan range from US $22-25 per ton or Rp 220 - 250 per kg. Coal production in South Kalimantan more or less 50 %from amount ofcoal production in Indonesia. This factory design is addressed to increase coal value by convert coal become syncrude n- pentane. So the coal have value sell higher level product. Atfull capacity, thisfactory yield 10.000 ton per year produce syncrude n-pentane with coal rawmaterial equal to 18537.05557 ton per year. Making ofslurry of coal represent unit processing of coal upon which base making of syncrude n- pentane, founded to convert coal become dilution through mixing process by using n-pentane solvent. Convert from coal become slurry is 76,79%. Syncrude processed to become Hydrogenation Coal Product use reactor fixed bed multi tube at condition of the operation 450 °C and 184 atm. Condition of the operation yield coal conversion equal to 94,82%. Catalyst the used is Co-Mo / al2o3. Because reaction take place by exothermic, the process require cooler water equal to 113800.6228 kg/ hour to take care ofthe condition ofoperation. Totalize valuable sale is Rp. 271,840,347,908.30. While production cost of Rp. 196,439,900,970.58, so that in earning advantage of Rp. 75,400,446,937.72. Totalizing capital investment ofRp 332,653,942,686.81 which consist of Rp. 288,911,019,704.38 in the form of fixed capital and of Rp. 43, 742,922,982.43 in theform ofworkingcapital. Economic parameter which usedfor the examination of to eligibility is ROI, POT, DCF, BEP, SDP. Result of calculation of the parameter is ROIB = 22.4041%, POTB = 3.0860year , DCF = 29.1848 %, BEP = 32.7215 %maximal production capacities, SDP = 18.2357%maximal production capacities. All the economic parameter show satisfying result so that this factory draw to be founded.
