摘要
Abstract
The problems of water system in methanol to olefin plant are analyzed. The maj or problems in quench system are the fouling on tower plates and the high solid content. The components with high-melting-point solidify on cold tower plates is the main course of fouling, and pre-spray before tower plate can handle this. PAM was used to decrease solid content of quench water. The maj or problems in washing system are the increase of pressure drop,and the decrease of heat transfer effect. It is analyzed that the gradient solidification of multi methyl benzene in system and blend with catalysts are the main reasons. Hence the washing tower should separate into several segments,and decrease the temperature gradient in segments while increase that between segments. Cyclone before washing tower is able to decrease solid content in washing water.关键词
