Recycling and utilization of calcium carbide slag
The production of CCS can be divided into wet and dry processes. In the wet process, slag is a mixture of the excess water and Ca(OH) 2 after the reaction of CaC 2 and water to produce acetylene. The dry slag is the Ca(OH) 2 powder with less water content after acetylene is produced by CaC 2 powder and water vapor reaction. As a …

The most common processes are air cooling, to yield a crystalline slag, and the granulation process, in which the slag is cooled rapidly, becoming amorphous. By comparison, the granulated slag has more possibilities of reuse due to its capacity to absorb water and its characteristic of hardening after adding water (Polese et al., 2006).
