Characterization of an industrial calcium hydroxide residue generated in acetylene manufacturing process
Keywords:
acetylene residual , granulometry , calcium hydroxide, neutralizationAbstract
The purpose of the work is to characterize, from the chemical, physical, granulometric and mineralogical point of view, an industrial residue of calcium hydroxide generated in the acetylene manufacturing process. Samples were first analyzed without neutralization; then the same procedure was performed using 98 % purity sulphuric acid. For both cases, the heating temperatures used were 500 °C and 900 °C. To identify the phases, diffraction patterns were obtained using copper radiation source (CuKα, λ = 1.5418 Å). It was determined that residual contains CaO and MgO, which guarantees its purity; heated at 500 °C, and without neutralizing, calcium hydroxide is transformed and there is loss of water and carbonate at 900 °C. In both untreated and neutralized waste, Calcium hydroxide is present.Downloads
