NW-Ⅲ新型分子筛在空分装置上的应用

Application of NW-Ⅲ novel molecular sieve in air separation device

灵石中煤化工空分装置采用立式双层床吸附器作为净化装置,原来吸附剂采用13X-APG型分子筛,吸附时间为4h,在不改变设备结构及工艺的前提下,采用新型分子筛(NW-Ⅲ),将吸附时间延长为6h,不仅节约运行成本,而且对空分装置稳定运行有利。

The vertical bunk bed adsorber is used as the purification device for the air separation device of the coal chemical in Lingshi.The original adsorbent uses a 13X-APG molecular sieve with a adsorption time of 4 hours without changing the equipment structure and process.The new type of molecular sieve(NW-Ⅲ)was used to extend the adsorption time to 6 hours,which not only saves the operating cost,but also facilitates the stable operation of the empty separation device.
