Abstract

Review terhadap studi kelayakan hasil pencairan batubara Banko dilaksanakanoleh tim due diligence yang diprakarsai oleh Puslitbang TEMIRA bekerjasamadengan peneliti dari ITB, UNSRI, Lemigas dan Pertamina. Pada pelaksanaannyasumber data dan informasi serta konsultasi dilakukan dengan bantuan BPPTdan PTBA, dan pemilik teknologi dalam hal ini NEDO/Kobe Steel Ltd. Evaluasistudi kelayakan mencakup observasi lokasi tambang dan pabrik, adumsi dasardan analisa sensitifitas, dengan focus studi paa aspek teknis dan keekonomianpencairan batubara Banko. Hasil due diligence telah dapat menerima katalisalami dapat menekan biaya produksi, tetapi resiko berupa suplai katalis secarakontinyu masih dipertanyakan. Oleh karena itu penggunaan katalis sintetis untukmenjamin suplai sanngat dianjurkan, namunbaik BPPT maupun NEDO/KobeSteel Ltd tidak dapat menyetujuinya. Tim due diligence menyatakan bahwapembesaran skala pabrik menjadi 6.000 ton per hari dari skala pilot plant 50 tonper hari dinilai terlalu berisiko. Pembesaran skala sebaiknya dilakukan melaluipabrik kapasitas 50 ton pe rhari sebelum masuk skala komersial. MeskipunNEDO/Kobe Steel dapat menerima keberatan tersebut, akan tetapi sangatdiyakini bahwa terbatasnya biaya dan waktu menyebabkanhal ini tidakmemungkinkan. Tim due diligence menekankan bahwa hasil studi kelayakantidak mengkaji secara rinci aspek teknis dan financial proses pemurnian untukmeningkatkan mutu minyak batubara hasil proses pencairan, bahkanmengandalkan Pertamina untuk mengambil peran tersebut. Dimintakan kepadakepada NEDO/Kobe Steel agar studi kelayakan pabrik pencairan batubaraberdasarkan pada perhitungan break even point, daripada menggunakan variasimodul kapasitas 6.000 ? 12.000 dan 36.000 ton batubara (daf) per hari. Akantetapi NEDO/Kobe Steel meyakini bahwa pendekatan tersebut sebaliknya dinilaileih mudah, sederhana dan cepat.Keywords: batubara Banko , due diligence, studi kelayakan, katalis Soroako

Abstract

Market coal briquette compartment in Indonesia is estimated still big enough,considering kerosene and firewood which was usually used as small industrialand rural household sector fuel progressively scarce and costly if withoutsubsidy. Coal briquette of lignit made of low rank coal without carbonizationprocess and without binder, so that can become alternative fuel which iscompetitif, safe, efficient and environmental friendliness. Volatile matter contentcan be decreased by using special design of stove to burn it by fire tongue on thesurface of stove to yield completely combustion. Continueing usage of coalbriquette as alternative fuel substitution of kerosene and or firewood especially inrural, can be conducted by given system and sustanable supply guarantee,quality improvement, economical charcoal burner device of the environmentalfriendly, efficiently and routine promotion activities.Kata kunci: briket lignit, bahan bakar alternatif, rumah tangga industri kecil

Abstract

There are 3 choices in accommodating power station facility which have beeninstalled to fulfill standard regulation of environmental quality which progressivelytighten. Firstly, facility modification of pulverized?coal fired power plant byapplying a flue?gas desulfurisation technology throw away to cost moneyinstallation of tired which can 20% of total cost development of it. Secondly,modification system of coal fired power generation become natural gas combinedcycle (NGCC) can reach low emission, but fuel cost relatively high, so willinfluence the electricity generating cost. Third, modification system of electricgeneration which have been installed by utilizing a mechanism of coalgasification is most efficient and best alternative to yield an environmentalfriendly of electric generation combined cycle. In this paper, writer try to make abasic design of circulating fluidized?bed coal gasifier using clay catalist relatedon third choice which expected applicable in the next future to come replacepower station system which have ended a period as well as newly even if.Kata Kunci: gasifier batubara unggun mengambang, katalis tanah liat,pembangkit listrik
