壳牌煤气化装置洗涤塔出口合成气带水原因分析及对策

Analysis of Reason on Water Entrained in Synthetic Gas at Scrubber Outlet in Shell Coal Gasification Plant and Its Counter measure

介绍了壳牌粉煤气化装置中洗涤塔工艺流程;分析了洗涤塔内部结构;阐述了洗涤塔出口合成气带水的现象及危害;找出了引起洗涤塔工艺气带水的原因;采取了相应的技改措施。结果表明,通过调整工况,消除了带液现象。

Autthor has introduced the process flow of scrubber in Shell pulverized coal gasification plant： has analyzed the internal structure of the scrubber; has described the phenomenon and the hazard of water entrained in synthetic gas at outlet of scrubber; has found the reason causing the water entrained in process gas of scrubber ; and has adopted the appropriate technical reformation measure. Result indicates that the phenomenon of liquid en- trained is eliminated by means of adjusting the operating condition.
