Abstract

Salah satu problem penggunaan batubara Indonesia adalah kandungan sulfur dan abu yang relatif tinggi sehingga dapat berdampak pada kerusakan alat pembakar dan pencemaran lingkungan. Flotasi merupakan salah satu metode untuk mereduksi kandungan sulfur (anorganik) dan abu batubara. Penelitian desulfurisasi dan deashing batubara asal daerah Mallawa (Sulawesi) dilakukan dalam sebuah alat kolom flotasi dengan sistem kontinyu. Diamati beberapa variabel flotasi yang dapat memberikan hasil desulfurisasi yang maksimum, diantaranya adalah variabel rasio campuran surfaktan CPO (Crude Palm Oil) terhadap bahan batubara, dibahas dalam artikel ini. Diperoleh rasio campuran optimum adalah 1:4, berdasarkan kondisi optimum variabel lain yang telah diperoleh sebelumnya yaitu waktu tinggal 60 menit, laju alir udara 1,22 liter/menit, pH 6,5 dan ukuran partikel batubara 169 m. Pada kondisi optimum ini kandungan sulfur batubara dapat direduksi dari 3,3% menjadi 0,93% atau recovery sulfur 72% dan kandungan abu dapat diturunkan dari 11,25% menjadi 9,75% dengan nilai kalor dapat dipertahankan 6000 kkal/kg. Batubara hasil desulfurisasi dan deashing ini telah memenuhi kriteria untuk digunakan sebagai bahan bakar di industri. Kata kunci: abu, sulfur, flotasi, nilai kalor, kontinyu, rasio CPO:Batubara The problem related to the utilisation of Indonesian coal is the high sulphur and ash contents of the coal which may defect the combustor units and pollute the environment. Flotation is one of the methods to reduce the inorganic sulphur and ash in coal. Research on desulphurisation and deashing of coal from Mallawa (Sulawesi) was performed in a continuous flotation column. Variables which give maximum desulphurisation were studied and covered in this article, e.g. mixing ratio of crude palm oil (CPO) surfactant to coal. It was found that optimum mixing ratio of CPO to coal was 1:4, based on optimum conditions previously determined, i.e. resident time of 60 minutes, air flow rate of 1.22 l/min, pH 6.5 and coal particle size of 169 m. In these optimum conditions, the sulphur content was reduced from 3.3% to 0.93% or 72% sulphur recovery, while the ash content was reduced from 11.25% to 9.75%, the calorific value was maintained at 6000 kcal/kg. The desulphurised and deashed coal meets the specification criteria of the industrial fuel. Key words: ash, sulphur, continuous flotation, caloric valve, ratio CPO:coal

Abstract

AbstractThe potential amount of coconut sawdust biomass in Indonesia is very abundant, so far it has not been utilized optimally and tends to be wasted as waste. Coconut sawdust with the main composition of carbon contains heat equivalent to light coal, which is around 4400 kcal/kg. Even though its calorific value is still low, it has the potential to be used as a solid fuel source or an alternative energy source. The calorific value of coconut sawdust can be increased through the pyrolysis process. A study has been carried out on the effect of nitrogen inert gas flowing continuously into the pyrolysis reactor of coconut sawdust biomass waste (Cocos nucifera) on the calorific value of the resulting charcoal. The aim of the research is to determine the effect and optimum flow path of nitrogen inert gas which gives the maximum calorific value of charcoal product. From this study it was concluded that the continuous flow of inert nitrogen gas into the pyrolysis reactor had an effect on increasing the calorific value of the charcoal product by up to 4% compared to not using the inert gas. The optimum nitrogen gas flow rate is 2 L/minute giving a maximum effective calorific value of 7200 kcal/kg

Abstract

Research has been carried out on the utilization of biomass waste of coconut trunk sawdust using the pyrolysis method to produce two products simultaneously, namely charcoal and liquid smoke. In order to obtain charcoal products with optimum calorific value, it is necessary to understand the optimum pyrolysis conditions. One of the optimum conditions, namely pyrolysis temperature, was studied in this research. Pyrolysis was carried out in a simultaneous pyrolysis reactor at a flow rate of argon inert gas into the reactor of 2 liters/minute and a pyrolysis time of 2.5 hours with pyrolysis temperature variations of 350, 400, 450, and 500°C, respectively. The study showed that the optimum temperature of 400oC was obtained which gave a yield of 34% charcoal with a calorific value of 7229 kcal/kg. Compared to the calorific value of the raw material for coconut sawdust which is 4400 kcal/kg, there was an increase in the calorific value of the pyrolysis product by 64%. Based on the optimum temperature condition, liquid smoke as a by-product was also obtained with a yield of 45%. Charcoal can be used as a solid fuel or as a bioadsorbent in the treatment of liquid waste or clarification of liquid food products such as virgin coconut oil (VCO). Grade 3 liquid smoke can be used as a biopesticide, while grade 1 liquid smoke can be used as a food preservative. Given the benefits of the two pyrolysis products, both of the products from the current research have a promising market value.
