The purpose of this study was to evaluate the economic feasibility of producing copper oxide (CuO) nanoparticles using the green synthesis method on an industrial scale for 10 years by evaluating from an engineering and economic perspective. Various economic parameters are used to analyze economic viability, including Gross Profit Margin (GPM), Cumulative Net Present Value (CNPV), Payback Period (PBP), as well as economic variations in sales, taxes, raw materials, labor wages, and utilities to ensure project feasibility. Technical analysis to produce 100 kg of CuO nanoparticles per day requires a total production cost of 220,322.850.00 IDR and the gross profit margin is 16,721,250.000,00 IDR per year. PBP analysis shows that the investment will be profitable after more than three years. This project can compete with PBP capital market standards because of the short investment return. The profit is relatively economical, so this project can be run for 10 years under ideal conditions. This research is expected to be a reference for technical and economic analysis of industrial-scale production of CuO nanoparticles

Copper oxide nanoparticles are essential technology materials that are utilized as catalysts in the chemical industry, as well as in photonic and electronic devices and medical applications. Due to their applications in advanced technologies, we have concentrated on the production of CuO nanoparticles using enhanced, cost-effective, and environmentally friendly synthetic techniques. In this paper, we have presented a green synthesis technique to successfully synthesis copper oxide nanoparticles (CuO NPs) utilizing copper (II) sulfate pentahydrate (CuSO4.5H2O) as precursor salt and Mentha Piperita leaf extract as a reducing and stabilizing agent during the synthesis process. The precursor salt solution and reducing agent were mixed in a 1:1 volume ratio at 50 °C. The CuO NPs synthesized were confirmed by the characteristics Surface Plasmon Resonance (SPR) peak in the UV-visible region. Also, the optical direct band gap energy of the CuO NPs determined from the Tauc plot was 3.26 eV. The FTIR spectrum analysis confirmed existence of functional groups of polyphenols from Mentha piperita L. leaf extract, which are responsible for the reduction of Cu2+ ions and effective stabilization of CuO NPs. All the peaks observed in the XRD pattern revealed the production of CuO NPs having monoclinic structure with an average crystallite size of 42.51 nm. The surface morphology of the CuO nanoparticles was detected using SEM analysis. Further, the synthesis mechanism of CuO NPs has also been investigated.

Simulation Results

AbstractThe rubber peptizer 2,2′-dibenzoylaminodiphenyl disulfide is typically synthesized from C7H5NS, NaOH, H2SO4, and H2O2, but these reactants were replaced with C6H4ClNO2, C2H6O, Na2S, S, and N2H4·H2O, and these raw materials effectively improved the synthesis yield, reduced the number of synthetic steps, and made the synthetic process greener. Although the catalyst is difficult to recover, it effectively avoids using ethanol as a volatile organic solvent. The Aspen Plus method was used to simulate the key processes in the synthesis in the experimental conditions as the boundary conditions. The simulation results show that the feed ratio of C7H5NS, H2O2, and C7H5ClO directly determines the yield of the reaction, and the equivalents of NaOH, H2SO4, and Na2CO3 indirectly affect the yield of the reaction by changing the reaction environment and controlling the formation of byproducts. The temperature of the ring-opening reaction and the acylation reaction should be maintained within 110–120°C to maximize the yield. The oxidation reaction temperature also directly affects the reaction yield and should be kept below 40°C. The simulation results are consistent with practical industrial production conditions. Based on the developed green synthesis process and the optimal process parameters obtained from the simulation, the industrial-scale production of 10,000 tons of 2,2′-di benzoyl amino diphenyl disulfide was carried out. Compared with that of o-nitrochlorobenzene, the yield of 2,2′-dibenzoylaminodiphenyl disulfide increased from approximately 72% to more than 90%. Using this method instead of the original synthesis method avoids the use of o-nitrochlorobenzene, which is neurotoxic; Raney nickel as the metal catalyst, which is difficult to recycle with existing environmental protection technologies; and ethanol as the organic solvent, which is associated with environmental problems. The amine tail gas that is easily generated in the original synthesis method is not generated in this system, and the drying step is eliminated.

ABSTRACTReliability of the electric power system and fulfil the certification of sustainable industries in the palm oil industry are offered by utilizing the potential of renewable energy sources as power plants. This research is aimed to analyze the technical and economic aspects of the Solar PV-Biogas power plant at PT. TBS. The method used in this research is hybrid parallel with the off grid network system. In manual calculations showed an optimal generating system consisting of an anaerobic digester with a lagoon capacity of 28,934.81 m3, 1,560 kW biogas generator, 4,040.22 kWp PV array, 2000 kW bidirectional inverter, and 10,125 units of batteries with capacity of 1,547Ah. Then the system is evaluated using HOMER Pro software with project lifetime of 20 years, and the total electricity production obtained during the life of the project is able to supply loads continuously with an average excess electricity about 25.23%/years of total production. Meanwhile, in the economic analysis of hybrid power plants require an initial investment (NPC) of Rp.233,553,169,589.30, with total CO2 emissions of POME 44,073.75 tons/year, then the cost of Certified Emission Reduction is obtained about Rp.6,611,062,500/year. The calculation of economic feasibility results in a Net Present Value of Rp.136.266.578.753, Payback Period of 13,8 years, and an Internal Rate of Return of 9,41%. Based on the result of techno-economic analysis in the research, it can be concluded that this hybrid generating system has the potential to be developed for study that is more detailed if it is to be implemented.Keywords: HOMER Pro, Off-grid, PT.
