| Summary: | PT Indocement Tunggal Prakarsa Tbk is one of the cement producing industries in Indonesia which has 12 factories spread across three regions, namely Palimanan, Citereup and Tarjun with a total production capacity of 20.5 million tons of cement per year. In an effort to meet the cement needs for infrastructure development, production capacity will be increased with similar conditions as in Plant 14, PT Indocement Tunggal Prakarsa Tbk. located in Citereup, Bogor, West Java. The cement production process is inseparable from the waste produced. Particulates are produced through dry production with raw materials used in the process including lime, silica sand, clay, iron sand and gypsum. With increasing production, coal needs will also increase. The recommended air pollution control system (particulate) is in the form of fabric filters and electrostatic precipitators which will be installed in the coal mill which functions as a grinding tool before entering the kiln. The process of selecting alternative controllers is carried out through weighting with the corresponding parameters of the equipment such as gas and particulate characteristics, efficiency, cost, maintenance flexibility and the area needed. Based on this analysis, the chosen air pollution control device is a pulse-jet type filter with an collection efficiency of 99.99%. The final design is also accompanied by ducting, fan and compressor. In addition to technical analysis carried out through the calculation of the system's technical design, non-technical analysis was carried out to assess the feasibility of the project in planning the development of an air pollution control system. Several analysis methods carried out include risk analysis, uncertainty analysis, sustainability analysis and life cycle analysis. A calculation of NPV (Net Present Value) gives the final result of Rp. 194.596.686.985,77 for 10 years operating time. It can be concluded that the air pollution control system at PT Indocement Tunggal Prakarsa, Tbk. is economically feasible. |
