The comprehensive utilization of calcium carbide slag was released in two groups

Recently, led by the green process and circular economy technology research team of the Institute of Process Engineering of the Chinese Academy of Sciences, China Huaneng Group Co.

Based on the unclear product index standards of calcium carbide slag-based desulfurization materials and the limited applicability of related product analysis methods in the actual application of the product, the project team proposed and promoted the release of two group standards
for the analysis method and product technical indicators of calcium hydroxide desulfurization agent based on calcium carbide slag.

The formulation of the above two group standards can supplement and improve the product standard system and help to achieve industrial interconnection
.

Calcium carbide slag is a bulk solid waste produced by the chlor-alkali industry, with an annual output of 30 million tons, and a large number of piles cause serious environmental pollution
