Abstract

The gas produced in solid waste disposal sites, particularly CH4 can be a local environmental hazard if precaution are not taken to prevent uncontrolled emissions or migration into surrounding land. Gas can migrate from solid waste disposal sites either laterally or by venting to atmosphere, causing vegetation damage and unpleasant odors at low concentration, while at concentration of 5-15 per cent in air, the gas may be form explosive mixture.Recently, a forest fire on the Indonesian islands of Sumatra and Kalimantan left not only Indonesia but neighboring countries as well covered under a thick cloud of haze. Some palm plantations and palm oil refineries once disposed of palm oil waste (Empty Fruit Bunches ) by drying them in ovens and then burning them in fields. This paper discusses some results of the experimental and theoretical investigations which conducted to examine effects of the utilization of palm oil wastes particularly Empty Fruit Bunches as the fuel of boiler on greenhouse gas emission.

Abstract

ABSTRACTExergy analysis was conducted in evaluating the performance of Muncipal Solid Waste Fired Steam Power Plant (PLTSa) to determine the locations and quantities of exergy losses. Wastes and exergy destructions in different processes of the plant were also been calculated. Total exergy available at incinerator input was 60.560,54 kW, consisted of 58.242,45 kW in MSW and 2.318,08 kW in the combustion air. The burning of 600 ton per day MSW in the PLTSa produced 8.482,83 kW Net Electric Power, accounted for 14,01 % of the overall exergy efficiency of the power plant. The plant produced electrical energy 59.447.673 kWh/year and reduced 240.900 ton MSW/year, thus contributing to CO2 emission reduction. Exergy efficiency of the turbine generator and condenser were 86,21 % and  78,48 % respectively. PLTSa component with the largest exergy destructions was incinerator-boiler (56,53 %), far exceeded the turbine generator (8,69 %), and condenser (3,79 %).Keywords: Exergy, Exergy Destruction, Steam Power Plant, Muncipal Solid Waste  (MSW), Exergy Efficiency.ABSTRAKPentingnya analisa eksergi dalam mengevaluasi kinerja PLTSa telah terbukti. Analisa eksergi PLTSa telah dilakukan untuk mengetahui lokasi dan jumlah kerugian eksergi. Limbah dan destruksi eksergi dalam proses yang berbeda telah diindikasikan. Hasil yang diperoleh menunjukkan bahwa total eksergi yang tersedia pada input Incenerator adalah 60560,54 kW. Nilai ini terdiri dari 58242,45 kW yang terkandung dalam MSW dan 2318,08 kW dalam udara pembakaran. Pembakaran 600 ton per hari MSW pada sistem PLTSa menghasilkan  8482,83 kW daya listrik bersih dan 14,01 % efisiensi eksergi keseluruhan pembangkit. Pembangkit menghaslkan energi listrik sebesar 59447673 kWh/tahun dan mengurangi timbunan sampah sebanyak 240900 ton MSW/tahun, sehingga berkontribusi dalam mengurangi emisi CO2. Efisiensi eksergi dari sistem turbin generator dan sistem kondensor masing-masing adalah 86,21 % dan  78,48 %. Komponen PLTSa dimana terjadi destruksi eksergi yang terbesar berturut-turut adalah pada sistem Insinerator-boiler sebesar 56,53 % , sistem turbine - generator 8,69% dan sistem kondensor 3,79%.Kata kuncis: Eksergi, Destruksi Eksergi,  PLTUSa, Sampah Padat Kota (MSW), Efisiensi Eksergi

Abstract

ABSTRACTScaling and corrosion are two major problems in operation of the Small Scale Geothermal Power Plant. This paper discusses some results of the study that was conducted to assess the scaling formation in the Kamojang 3 MW Small Scale Geothermal Power Plant. The result of the study concluded that scaling occurred on the nozzle and steam turbine blade where the main minerals contained in sample A (solid) are Tridymate (SiO2), Pyrite (FeS2) and Chlorite (ClO2). While in sample B (sand) where the main mineral contained in the sample is Tridymate (SiO2), Pyrite (FeS2), Plagioclase (Na,Ca)(Si, Al)4O8 and Chlorite (ClO2). The analysis of this scaling was done by XRD (X-Ray Diffraction) method.  Scaling of the nozzle of the steam turbine causes the steam flow rate to decrease, thus lowering the power that the Small-Scale Geothermal Power Plant generates because the power generated by the Small-Scale Geothermal Power Plant is directly a function of the steam flow rate and the enthalpy difference between the inlet side and the outlet side of the turbine. However, scaling does not occur on the exit side of the wellhead KMJ 68 because the concentration of silica is very small that is 0.05 ppm at geothermal steam temperature 200.5°C.Keywords: geothermal steam, scaling, corrosion, Small Scale Geothermal Power Plant ABSTRAKScaling dan korosi merupakan dua masalah yang sangat serius ditemukan pada pengoperasian PLTP Skala Kecil. Tulisan ini membahas sebagian hasil studi yang dilakukan untuk mengkaji pembentukan scaling pada PLTP Skala Kecil Kamojang 3 MW dan pengaruhnya pada daya listrik yang dihasilkan oleh PLTP Skala Kecil. Dari hasil kajian dapat disimpulkan bahwa scaling terjadi pada Nozzle dan sudu-sudu turbin dimana mineral utama yang terdapat didalam sampel A (berupa endapan/padat) adalah Tridymate (SiO2), Pyrite (FeS2) dan Chlorite (ClO2). Sedangkan pada sampel B (endapan lepas/pasiran) dimana mineral utama yang terdapat didalam sampel adalah Tridymate (SiO2), Pyrite (FeS2), Plagioclase (Na,Ca)(Si,Al)4O8 dan Chlorite (ClO2). Analisis scaling ini dilakukan dengan menggunakan metoda XRD.(X-Ray Diffraction). Scaling yang terjadi pada bagian nozzle dari turbin uap menyebabkan laju aliran uap berkurang sehingga menurunkan daya yang dihasllkan PLTP Skala Kecil karena daya yang dihasilkan PLTP Skala Kecil secara langsung merupakan fungsi dari laju aliran uap dan perbedaan entalpi antara sisi masuk dan sisi keluar dari turbin. Akan tetapi, tidak terjadi scaling pada sisi keluar kepala sumur KMJ 68 karena kosentrasi silika sangat kecil yaitu sebesar 0,05 ppm pada temperatur uap panas bumi 200,5oC .Kata kunci : uap panas bumi, scaling, korosi, PLTP Skala Kecil,
