Abstract

The dual fuel line 2 100MW steam power plant (PLTU) is one of the power plants owned by PT Riau Andalan Pulp and Paper. To produce steam PLTU line 2, PT RAPP used biomass as the main fuel and natural gas as an alternative fuel to achieve the required steam production target. The combination of exergy analysis (second law of thermodinamics) with economic analysis is exergoeconomic. With this exergoeconomic analysis the value of losses in each component of the steam power plant is more noticeable because it is already in the value of the currency. By carrying out this research the value of the cost of loss can be identified specifically, from the highest loss to the lowest loss. At the dual fuel line 2 PT RAPP 100MW steam power plant the biggest cost of the loss was at the boiler at US$ 533.048,48/hour, followed by the HP pre-heater 2 for US$ 262.869,97/hour, the HP pre-heater 1 for US$ 83.153,52/hour, condenser US$44.063,03/hour, pump 2 US$42.846,85/hour, feedwater tank US$34.849,08/hour, steam turbine US$234.05/hour and the smallest was pump 1 US$71,48/hour. With a total value of a loss of US$ 1.011.509,52/hour. Through this research, it was expected that the value of the cost of losses due to exergy destruction can be reduced.

Abstract

Oil palm empty fruit bunches can be used as a renewable energy source made into bio-coal through the torefaction process. The combustion value of oil palm empty fruit bunches is expressed in terms of heating value to indicate the amount of energy obtained. The heating value is also known as the heat value of the fuel, which is one of the important parameters for fuel quality. This study aims to calculate the high heating value of bio-coal theoretically and compare it with experimental results. High heating value is calculated based on the enthalpy of combustion (hC), which indicates the amount of energy released during the combustion process when the fuel is completely burned at a certain temperature and pressure. In other words, the heating value of the fuel is equal to the absolute value of the enthalpy of combustion of the fuel. The theoretical calculation results are different or smaller than the experimental data. Experimentally the high heating value with a sample weight of 0.25 kg, 0.5 kg and 1 kg is 20334 kJ/kg, 23578 kJ/kg, 26346 kJ/kg respectively, while the theoretical high heating value for sample weight 0.25 kg, 0.5 kg and 1 kg respectively amounted to 22053.60 kJ/kg, 22751.66 kJ/kg, 24147.69 kJ/kg. Variability in biomass composition such as chemical elements or components, moisture content, particle size, and volatile matter content can have a significant effect on combustion value

Abstract

Excessive use of fossil energy has negative impacts, which can cause climate change and environmental degradation. Thus, there is a need to find alternative, more sustainable energy sources. Biomass derived from Empty Fruit Bunch (EFB) waste is a newfound renewable energy source. However, its utilization is not optimal due to its low heating value and high chlorine (Cl) and potassium (K) content, which can interfere with combustion. EFB is washed with peat water to reduce potassium and chlorine content, and the torefaction process is used for combustion. This research aims to develop bio-coal production from empty fruit bunches using the torefaction method using fixed beds and continuous tubular reactors. The production process development also aims to obtain a larger production capacity than previous studies. This study uses varying weights of EFB produced into bio-coal, namely 250, 500 and 1000 grams, with a torefaction process temperature of 200°C for 30 minutes. As a result, the peat water flow rate decreased K, Cl and K2O content to the lowest content reduction value, which amounted to 8.31%, 0.42% and 3.96%, respectively. The heating value of bio-coal produced in a fixed bed reactor is 26,166 kJ/kg, while in a continuous tubular reactor, it is 21,720 kJ/kg. Based on these results, the fixed bed reactor shows a higher heating value than the continuous tubular reactor. The heating value obtained from these two types of reactors is comparable to sub-bituminous coal, which is usually used in steam power plants.
