| Abstract: | Comprehensive utilization technology of waste carbide slag by-produced in PVC production and alkali waste by-produced in hydrazine hydrate production was discussed. Under specific conditions, caustic soda and calcium carbonate powder that could be recycled and utilizated was obtained after reaction of carbide slage and alkali waste. Caustic soda after concentration was reused in hydrazine hydrate unit for producing sodium;calcium carbonate powder was sent to power plant as desulfurization agent. The technology has fine economic and environmental benefits. |
