Analisa Efisiensi Penyerapan Gas Hydrogen Fluoride (HF) yang di hasilkan Tungku Reduksi Aluminium oleh Alumina (Al2O3)

Abstract

Aluminum smelting electroliysis implement process that have been found by Hall-Heroult. This process requires the anode, cathode and electrolyte solution as the raw material alumina smelter in the can from bauxite refining. in this process of hydrogen fluoride gas (HF) be so byproduct after carbon dioxide (CO2), and this process takes place every time. so that the resulting gas HF always there. HF gas produced is the result of the reaction between the carbon anode chlorine cliorite (Na3AlF6).HF gas is reacted with the alumina which serves as adsorbent inside the reactor by regulating the flow of alumina to the gas HF, This is done to reduce or even eliminate HF gas coming out of the chimney. if HF gas that comes out in a quantity that many will cause poisoning and even death.HF to determine levels of gas coming out of the chimney.necessary to analyze the efficiency of gas absorption by the alumina HF. in this case, the efficiency of absorption in PT Indonesia AsahanAluminium (Persero) is optimal. This is evidenced from the results of absorption, respectively for 99.85% and 99.86% with gas concentration HF disposed of 0.33 mg/Nm3 and 0.20 mg/Nm3.
