| 제목 | Economic feasibility of nano-porous silica and electricity production from rice husk |
| 초록 | Paddy rice is one of the main crops (sugar can, maize, wheat, etc), with about 500 million tons in 2021. Rice husk is produced as an agricultural byproduct during the milling process of paddy rice. One ton of paddy rice produces 220 kg of rice husk, and 90~176 kWh of electricity can be produced using rice husk. After rice husk combustion, 18-20% of the rice husk remains rice husk ash (RHA) as a by-product. RHA is mainly composed of carbon and silica (>90%), and silica can be used in industrial fields as reinforced rubber additives (tires), adhesives, and adsorbents. In general, silica is produced from silica sand at 1400~1500 ˚C, but rice husk is burned at a relatively low temperature of 650~800˚C to produce RHA. In this study, the techno-economic feasibility of the processes for producing nano-porous silica and electricity from rice husk was investigated. Based on the process simulation using ASPEN Plus, the total capital investment (TCI), total production cost (TPC), return on investment (ROI), and payback period (PBP) were calculated to determine economic feasibility. |
