Recovery of Pure Slaked Lime from Carbide Sludge: Case Study of Lagos State, Nigeria | Chapter 05 | Current Perspectives to Environment and Climate Change Vol. 3
Carbide sludge is the by-product of
reaction between calcium carbide and water in the production of acetylene gas
for welding purposes. This by-product is discarded as waste due to high content
of impurities as a result of the reactants and reaction processes. In this
research work an attempt was made at developing an appropriate process
technology for the recovery of pure slaked lime from Nigeria’s automobile
welders’ carbide sludge using solubilisation and evaporation process
technology. The percentage purity of the slaked lime recovered through the
process was 88%. The recovered slaked limes had pH of 11.93, were soluble in
glycerol and dilute acid, insoluble in alcohol, and sparingly soluble in water.
The optimum percentage yield was 78.2% at a ratio of 1:1000(w/v) of sludge to
water held for 24 h at room temperature.
