The performance of Electrostatic Precipitator (ESP) is significantly affected by complex flow distribution. Recent years, many numerical models have been developed to model the particle motion in the electrostatic precipitators. The computational fluid dynamics (CFD) code FLUENT is used in description of the turbulent gas flow and the particle motion under electrostatic forces. The gas flow are carried out by solving the Reynolds-averaged Navier-Stokes equations and turbulence is modeled by the k-ε turbulence model. The effect of electric field is described by a series equations, such as the electric field and charge transport equations, the charged particle equation, the charge conservation equation, the mass and momentum equations of gas, the mass and momentum equations of particle and so on. The particle phase is simulated by using Discrete Phase Model (DPM). The simulations showed that the particle trajectory inside the ESP is influenced by both the aerodynamic and electrostatic forces. The simulated results have been validated by the established data.

Pencemaran udara dapat dikategorikan sebagai pencemaran yang sangat berbahaya dan juga memberikan dampak yang cukup besar bagi lingkungan disekitarnya. Cyclone dan electrostatic precipitator (EP) adalah contoh alat yang dapat mengurangi pencemaran udara di industri semen. Studi ini bertujuan untuk mengevaluasi kinerja cyclone dan EP. Perhitungan kinerja cyclone ditinjau dari jumlah putaran dalam gas dan diameter partikel, dan kinerja EP ditinjau dari kecepatan migrasi partikel dan resistivitas. Metode yang digunakan dalam penelitian ini adalah perhitungan evaluasi dengan menggunakan data aktual. Data tersebut berupa laju alir, densitas, diameter partikel, kecepatan gas inlet, data desain EP dan Cyclone, serta emisi partikulat dan kondisi alat pada saat operasi. Hasil evaluasi menunjukkan effisiensi cyclone sebesar 95,5% dan EP sebesar 98,72%. Kedua nilai efisiensi ini masih memenuhi standar efisiensi alat, yang berarti kinerja cyclone dan EP tersebut masih baik.
