Abstract

In this study, the effect of diameter particle and the effect of inter-particle cohesion force due to liquid bridge formation on the minimum fluidization velocity in the fluidized bed have investigated. Also the effect of inter-particle cohesion force on a fluidization condition of the bed has observed by video camera. The investigation results showed bigger diameter can give higher minimum fluidization velocity, and stronger inter-particle force can give higher minimum fluidization velocity, and then make a quality of fluidization of bed lower. Using with this investigation results, the mechanism of fouling and slagging phenomena, which are happen in the coal-fired boiler can be explained.

Abstract

Until now, the use of biogas in Palm Oil Mill (POM) is still limited to use as a fuel for Biogas Power Plant or utilize an additional boiler fuel. The use of biogas to be taken to other places is constrained by the remote location of POM and the transportation method. However, by converting biogas into bio-CNG, it can be used as vehicle fuel. The investment feasibility study of bio-CNG production facilities was carried out for two case studies, in POM with a capacity of 30 t/hr and 60 t/hr. The funding uses 100% of the equity fund and subsidy of the Joint Crediting Mechanism (JCM) scheme. Using the JCM scheme, the value of investment gets 50% funding assistance, and carbon credits from the reduction of Greenhouse Gas (GHG) emissions belong to the Japanese government. As a result of the study, it is known that the development of bio-CNG production facilities with 100% equity, IRR of both POM is below 11.08%, so it is not economically feasible. From the sensitivity analysis, it indicates that the increase in selling price of bio-CNG of +10%, a decrease in the investment of -10%, an increase in biogas input of +10% still cannot increase the Internal Rate of Return (IRR) value. Funding from JCM of 50% of the investment value increased the IRR value of 30t/hr and 60t/hr increasing from 6.54% to 18,29% and from 8.13% to 20.82%, respectively. The values of IRR became higher rather than the benchmark (IRR=11.08%). Carbon emissions reduction of the operation of the bio-CNG production facility and the use of bio-CNG for vehicle fuels in both of POMs are 38,735 tCO2/yr and 77,471 tCO2/yr, respectively. Using subsidy from carbon credits or other incentives will significantly help improve the economically feasible of bio-CNG production facilities in POM.

Abstract

The TKDN (Domestic Component Level) assessment of goods and services is a method to determine local manufacturers/industrie’s capability to create quality products internationally standardized. This study assessed the salt factory's TKDN to increase the NaCl content, based on cost-based analysis stipulated at the Minister Industry Regulation No.16/M-IND/PER/2/2011. Meanwhile, the TKDN of salt production was assessed based on process-based analysis stipulated in Minister Industry Regulation No.16/2020. According to the cost-based analysis results, the goods and services at the pilot project stage had the TKDN value of 27.4%. However, due to an increase in the number of main domestic components at the commercial stage, this value increased to 70.9%. Meanwhile, according to the processed-based analysis results, the salt production had the same processes at the pilot project stage and commercial stages. The TKDN value of 85.5% was obtained for the two stages. The value is relatively high because the raw material is produced locally with the local labor and used work tools owned by the local industry. The cost-based analysis was found to be highly dependent on the equipment component’s origin, while the process-based analysis depends on the origin of labor, works tool, and material owner. Keywords: domestic component level; process-based analysis; cost-based analysis; salt factory; salt product.
