management of calcium carbide sludge

Carbide sludge management in acetylene producing

Carbide sludge (10.4-11.5 tonnes day(-1)) is generated from the reaction of calcium carbide (900 kg) and water (6,000 L) in the production of acetylene (2,400 m3), in three selected acetylene manufacturing plants. The sludge (of pH 12.2 and containing Cu, Pb, Fe, Mn, Ni and Zn ions whose concentrations exceed the Department of Environment limits for industrial wastewater) was treated by vacuum

Recovery of pure slaked lime from carbide sludge: Case

Calcium carbide sludge is generated during the process of reaction between calcium carbide and water in the pro-duction of acetylene for welding purposes. The reaction of calcium carbide with water was discovered by Friedrich Wohler in 1962 CaC 2 +2H 2O → C 2 H 2 +Ca (OH) 2. → (2) This reaction is the basis for industrial manufacture of

Water Treatment Sludge–Calcium Carbide Residue

09/09/2017· In this research, water treatment sludge (WTS) calcium carbide residue (CCR) geopolymers were evaluated as a sustainable masonry nonbearing unit. The WTS was a by-product from a water treatment plant, whereas CCR was a by-product from an acetylene gas factory in Thailand. Sodium hydroxide solution (NaOH) and sodium silicate solution (Na 2 SiO 3) were used for the

Strength Properties of Remoulded Sludge Stabilized with

calcium carbide residue(CCR) gained from acetylene plants was used for stabilization of remoulded sludge. Based on unconfined compression test and direct shear test, strength properties of remoulded sludge stabilized with CCR were investigated in this paper. Unconfined compressive strength, cohesion and internal friction angle of remoulded sludge improved significantly after adding CCR, and

Calcium Carbide Sludge Scientific.Net

Substituting calcium carbide sludge for limestone is an effective method for CO 2 emission reduction in cement industry and has developed rapidly in recent years in China. The purpose of this study is to determine the life cycle CO 2 emission of cement clinker produced with calcium carbide sludge as secondary raw material. The results show that compared with general cement clinker, the life
