查询词典 causticization

A two-step method of causticization and precipitation technology was used to revive spent caustic of ethylene cracking, and various conditions which affect regeneration efficiency of the reaction were studied.

采用苛化及化学沉淀两步工艺对乙烯裂解废碱液的再生进行了研究，考察了影响再生效果的各种条件因素。

The process waste of making PVC- carbide slag ,its main composition is Ca 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Ca2，将电石渣用于碱回收苛化，试验，结果表明是完全可行的。

The caustic was regenerated from the spent caustic in an ethylene plant which adopted precipitation with a oxide of transition metal and causticization.

采用过渡金属氧化物沉淀法和苛化法处理乙烯裂解废碱液得到再生碱液，考察了再生碱液循环使用的可行性。

When the causticization time was longer than 120min and higher than 80℃ with 1.1:1 of stoichiometric ratio, and the precipitation was longer than 30min at 80℃ with n:n(Na2S) being 1.45:1, the NaOH concentration after reviving was denser than 8%, and the revived caustic approximately had the same physical property and adsorption of CO2 as the new caustic.

结果表明：苛化反应温度大于80℃，反应时间超过120 min，n：n(Na2CO3)为1.1：1， CuO沉淀反应温度为80℃，反应时间30 min，n：n(Na2S)为1.45：1等条件下，再生后的NaOH含量可在8%以上，并且再生碱液的物性以及再生碱液对CO2吸收速率上与新鲜碱基本相同。
