丙酮氰醇装置自开工以来真空泵一直采用的是蒸汽喷射泵，真空系统一直不稳定，蒸汽喷射泵经常出现氢氰酸聚合现象，导致装置不能长周期、高负荷运行，同时浪费了大量的蒸汽。为了解决这一问题，装置对真空系统进行了彻底改造，保证了装置长周期高负荷运行，针对装置真空系统改造前后的效果进行了分析。

The steam-jet pump was always used in the vacuum system during the operation of the acetone cyanohydrin equipment. But the phenomenon of hydrocyanic acid polymerism was oftentimes encountered in steam-jet pump due to the instability of the vacuum plant, which resulted in the short running period of the equipment and high load to waste a large amount of steam. In other to resolve this issue, the vacuum system was transformed to ensure the long period operation of the equipment under high load. At last, operation effects of the equipment before and after the transformation were analyzed.
