Abstract

Rotary dryer are best suited for drying materials that are not easily broken and resistant to heat and require time for rapid drying. The drying process of corn kernels with rotary dryer by using biomass fuels becomes alternative to replace heat sources derived from the burning of fuel oil (BBM), as fuel prices tend to increase. While the availability of which decreased. The changed variable used is the air flow rate of the dryer air (3.5 m/s, 4 m/s, 4.5 m/s, 5 m/s and 5.5 m/s) and drying time (10 minutes, 15 minutes, 20 minutes, 25 minutes, and 30 minutes). The results showed that the moisture content of corn kernels was influenced by the drying air flow rate and the duration of drying time. The result of drying of corn kernels with the lowest water content is 9.66% achieved in the process conditions with drying air temperature 60oC with the air flow rate of the dryer air 5.5 m/s. Meanwhile, the highest rate of drying is 0.00307 kg/second. In testing the variation of drying time, the results of drying corn kernels with the lowest water content are 2.2% achieved at 30 minutes drying time and the highest drying rate was achieved at 30 minutes drying time, which was 0.002448 kg/s.

Abstract

Coal gasification is the process of converting solid into a gas mixture that has fuel value. Coal gasification will produce gas in the form of synthetic gas (syngas) with the main components consisting of carbon monoxide (CO), hydrogen (H2), and (CH4) gas. By converting coal using gasification as a clean energy producer, a blower as a regulator of air flow, cyclones as a tar separator and a gas cooler. The results of this study are the rate of fuel use, the rate of burning ash, the specific gestation rate, the specific gas production rate, the syngas flow rate, the flash point calorific value, and the efficiency of the classification process. The decrease in the combustion air flow rate will tend to make the combustion temperature and the calorific value become smaller so that the efficiency will also decrease. The best efficiency occurs at the largest airflow rate of 3.15 m/s with an efficiency of 84.62%.The increase in the mass of the husk that is filtered will cause an increase in the composition of CH4 and H2, as well as a decrease in CO2 and CO. By filtering the mass of rice husks, the LHV value will increase.

Abstract

Coal gasification is the process of converting low rank coal into syngas which can be used as fuel. One of the factors that affect the quality of syngas is the size of coal particles. Meanwhile, to produce clean syngas, the gas from the combustion reactor is flowed through a packed bed absorber filled with marbles to reduce the incompatible particulate gases that are still contained in the syngas. The variations in the size of the coal used in this study are 3-4 cm, 5-6 cm, and 7-8 cm. While the variation of the height of the packing absorber filling used was 9.75 cm, 19.5 cm, 29.25 cm and 39 cm. The composition of the best combustible gas from the variation of coal size and the variation in the filling height of the absorber packing is found in the coal size 3-4 cm, and the packing filling height is 39 cm. With combustible gases (CO, H2 and CH4) produced by 10.9%, 10.5% and 0.9%, the volume of O2 and CO2 is 0.1% and 10.1%, the syngas volume of the absorber output is 2473.47 m3 and the LHV syngas is 6.932 MJ/kg.

Abstract

Biodiesel merupakan salah satu sumber energi alternatif yang dapat di perbaharui dan mampu untuk mengurangi ketergantungan energi nasional terhadap energi fosil. Biodiesel diproduksi dari minyak tumbuhan atau lemak hewan. Minyak nabati yang dapat digunakan sebagai bahan baku adalah minyak jelantah. Minyak jelantah mengandung asam lemak bebas atau Free Fatty Acid (FFA) yang tinggi. Penurunan kadar FFA dilakukan melalui cara ekstraksi menggunakan DES yang terbuat dari campuran Choline Chloride dan Ethylene Glycol dengan rasio molar 1:2. Dalam penelitian ini dlakukan variasi rasio molar Minyak Jelantah:DES sebesar 1:1, 1:2, 1:3, dan 1:4, variasi kecepatan pengadukan 150 rpm dan 300 rpm, dan variasi waktu selama 60 menit dan 120 menit pada suhu 60oC. Hasil penelitian menunjukkan bahwa rasio molar terbaik adalah 1:4, kecepatan pengadukan 300 rpm, dan waktu selama 120 menit dengan penurunan FFA hingga 0,55%.

Abstract

Global environmental concerns requiring excellent air quality have prompted the development of a variety of eco-friendly energy sources. Hydrogen gas is an environmentally friendly option that may be created using an electrolysis device that converts water into hydrogen (H2) and oxygen (O2). In this study, a dry cell electrolyzer with a polyvinyl alcohol (PVA) membrane was used as a separator between two stainless steel 316 electrodes to generate a high hydrogen yield. The hydrogen gas production from the dry cell electrolyzer was determined using gas chromatography. The results showed that using a KOH electrolyte and a PVA membrane considerably enhanced the hydrogen gas composition. Hydrogen gas compositions after electrolysis using a dry cell electrolyzer without a PVA membrane and KOH electrolyte concentrations of 0 M, 0.04 M, 0.07 M, and 0.11 M being 13.70%, 25.10%, 32.50%, and 15.60%, respectively. With a PVA membrane, the hydrogen compositions were 71.50%, 89.10%, 80.50%, and 84.60%, respectively. The results of these experiments show that the most hydrogen gas was produced utilizing a dry cell electrolyzer with a PVA membrane and a 0.04 M KOH electrolyte concentration. When a PVA membrane and a KOH electrolyte are utilized in electrolysis, the hydrogen gas composition improves significantly compared to when either is utilized.
