Study on Application of Red Mud Wash Liquor Causticization Technology;
赤泥洗液苛化技术应用研究
The process waste of making PVC-carbide slag,its main composition is Ca(OH) 2,can replaces the lime for causticization on the theoretics.
生产聚氯乙烯的厂家有大量废弃物——电石渣,其主要成分为Ca(OH)2,将电石渣用于碱回收苛化,试验,结果表明是完全可行的。
Causticization was adopted to regenerate spent caustic from ethylene plant, wherein the conversion rate of sodium carbonate was over 80 % and the causticization rate of the equilibrium solution was over 90 %.
采用苛化法对乙烯裂解废碱液进行处理,Na2CO3的苛化转化率在80%以上(平衡反应液的苛化率在90%以上);废碱液的反复再生和利用对碱液的吸收性能没有显著影响,再生碱液可以满足吸收裂解气中CO2等酸性气的要求。
