不停产富油清洗终冷塔的实践研究

Practice and study on “on-stream”cleaning of final cooler by rich oil

针对终冷塔内填料堵塞、煤气阻力增大等问题,采用富油对终冷塔进行不停产清洗,不但有效降低了煤气阻力,解决了生产难题,而且减排大量的有毒有害气体,消除了检修过程中的不安全因素,创造了一定的经济效益。

To solve the problems of packings blockup and increasing resistance in the final cooler, use rich oil to clean the final cooler under ＂on-stream＂ condition. Consequently, the resistance to gas is reduced,and the emission of toxic and harmful gases is largely reduced, which makes maintenance safer. It is economic beneficial to some extent.
