因循环冷却水加药不当,产生大量泡沫,使水夹泡沫进入分子筛吸附器,分子筛失去吸附能力,水分进入空分塔,影响空分设备的正常运行。介绍了故障的处理措施和效果,总结了循环冷却水处理和分子筛纯化系统操作方面的经验。 Due to improper dosing of circulating cooling water, a large amount of foam is generated, so that the water entrained foam enters the molecular sieve adsorber and the molecular sieve loses its adsorption capacity. The moisture enters the air separation tower and affects the normal operation of the air separation plant. The treatment measures and effects of failure were introduced, and the experience of operation of circulating cooling water treatment and molecular sieve purification system was summarized.
