摘要
为了提高浓硝酸装置的生产规模,开封晋开化工公司将精馏塔散堆填料改为规整填料,并对改造前后的有关工艺参数进行了对比,经过改造单塔年产量可增加1 500～2 000 t,增加产值300余万元,具有明显的经济效益。
For the production expansion of concentrated nitric acid in Kaifeng Jinkai Chemical Industrial Company, a new high efficient regular packing tower was applied instead of the random packing.Compared with the process parameters between the regular packing and the random packing, it concludes that the output of single tower has increased 1 500-2 000 t annual.This process will earn 3000 thousand yuan per year.
