Abstract

The utilization from oil palm empty fruit bunches is still limited. One alternative to the utilization of oil palm empty fruit bunches is by extracting potassium hydroxide from the ashes of oil palm empty fruit bunches. This study aims to determine the effect of temperature and extraction time using the single-stage method on the yield of potassium hydroxide. The dry ash from oil palm empty fruit bunches is reashing in the furnace and sieved with a 200 mesh sieve then extracted using water as a solvent at a temperature of 70oC, 80oC, 9 oC and extraction time of 4, 5, 6 hours. Ash extraction of oil palm empty fruit bunches at 90oC and 6 hours resulted in a potassium hydroxide yield of 51.37%. The results showed that the yield of potassium hydroxide increased with increasing temperature and extraction time. Keywords: extraction, oil palm empty fruit bunch, potassium hydroxide, single-stage

Abstract

Palm frond is biomass that has not been widely used as a renewable energy source. Torrefaction is a pretreatment process to improve the quality of the biomass as solid fuel. The aim of this research was to determine the condition of the process to the increase in calorific value torrefaction product. Results of the research is the calorific value and the proximate analysis torrefaction products such as moisture content, ash content, volatile content, and the content of fixed carbon. Torrefaction product calorific value in the range 17.700-19.800 kJ/kg.Key words: biomass, oil palm frond, renewable energy, solid fuel, torrefaction,

Abstract

Biomass gasification is a technology that can be used to convert biomass into gas fuel, chemicals, and energy which is more convenient and usable. The quality of the resulting product depends on the of gasification agents such as air, steam, oxygen, and process parameters such as temperature, type of biomass, and equivalent ratio. The biomass gasification process presents the mathematical model that has been given and solve the modeling with non-stoichiometric thermodynamic equilibrium method. The non-stoichiometric thermodynamic equilibrium model involves minimizing the Gibbs free energy. This model is useful for further research if there are changes in the gasification agent and process parameters.Keywords : biomass gasification, gibbs free energy, non-stoichiometric

Abstract

The non-stoichiometric thermodynamic equilibrium simulation program for the biomass gasification process was developed using the Python programming language. It is featured with a GUI (Graphical Users Interface), to facilitate user interaction. The program is designed to calculate the composition of gas producer with 6 components involved, they are CH4, CO, CO2, H2, N2, and H2O. The design of computational algorithms for calculating non-stoichiometric thermochemical equilibrium models is converted into Python code. The GUI consists of input and output facilities in form of tables and graphs of calculation results. The input facility is designed in such a way that the user can vary the gasification temperature and the equivalent ratio. The calculation results of the simulation program are verified with the calculated data manually to ensure that there are no errors in the algorithm or writing program code. It is also compared with the experimental data from previous studies to see the accuracy of the thermodynamic model in predicting the composition of gas producer. The non-stoichiometric thermodynamic equilibrium simulation program for the biomass gasification process can predict the composition of producer gas with a fairly good level of accuracy and can be used as a learning medium in studying thermodynamic equilibrium.

Abstract

Functioning industrial waste as raw material or as a product is an achievement that will continue to be optimized, especially in industries where the amount of waste is significant. Pulp and paper mills produce waste in the form of solid, sludge, liquid and gas. The objective of this research is to extract the element ferrum contained in one of the solid wastes in pulp and paper mills. By using two fatty amine extractor, lauryl amine and stearyl amine with ethanol and n-hexane as solvents. The results showed that the use of stearyl amine as an extractor and n-hexane as a solvent with operating conditions of 4 hours and a dose of 5 grams gave the best results with an extraction yield of 10,964 mg/kg.

Abstract

The pulp and paper industry continues to grow and produces large amounts of fly ash waste from the biomass combustion process. Alternative waste management besides landfills needs to be developed so that the use of fly ash can be ecologically and economically acceptable, such as for land applications in industrial plantations, especially on peat soils. This paper presents the results of the analysis of micro nutrients from fly ash from pulp and paper mill waste that can be used for agriculture and forestry. The elemental content of boron (B) and zinc (Zn) can be detected in fly ash samples both by lauryl amine extraction and stearyl amine extraction, where the optimum amount is obtained using 15 gram of fatty amine and n-hexane solvent with a processing time of 4 hours. Stearyl amine gives a higher yield than lauryl amine because it has a longer saturated carbon chain.
