聚乙烯醇聚合二塔的技术改造

Technical reform of No.2 polymer distillation column of polyvinyl alcohol unit

对生产聚乙烯醇的聚合二塔工艺进行了计算机模拟计算 ,采用高效导向筛板对其进行技术改造 ,达到了节能、降耗、扩产。

The parameters of No. 2 polymer distillation column were calculated and simulated with computer. The flow-guided sieve-trays with high efficiency were applied in the technical reform of the column. The targets of economization of energy, decreasing material consumption, increasing capacity and raising the product quality have been achieved after technical reform.
