Evaluation of Electrostatic Precipitator Performance at Raw Mill Plant Unit 11 of PT Indocement Tunggal Prakarsa Tbk. Bogor, West Java

Abstract

PT Indocement Tunggal Prakarsa is a cement manufacturing company whose production activities involve grinding and burning materials, resulting in environmental pollution in the form of dust into the air. These particulate emissions originate from the Raw Mill unit. The maximum standard limit applied to PT Indocement is 60 mg/m3. Efforts to minimize dust generated in this unit include installing dust control devices such as Electrostatic Precipitators (EP), preventing dust from being released directly into the atmosphere. Electrostatic Precipitators are devices that function as dust collectors. Their efficiency in capturing dust can reach 99.96%. In other words, almost all dust can be captured by Electrostatic Precipitators. The factor influencing the increase in dust emissions in these devices is the inlet temperature. The higher the temperature, the higher the resistivity of the dust, making it more difficult to capture.
